Best Angle Grinder Buying Guide

What is an angle grinder?

An angle grinder is an electrically driven machine with a fast rotating round grinding wheel. Since an angle gear is for the drive, explained that the name of the device. In some regions, great nicknames are also given to the angle grinder, such as cut-off grinders, separators, separating worms, grinding wafers, fire wheels or flexes. The name Flex is derived from the first manufacturer. In 1954, the company Ackermann and Schmitt from Steinheim a der Murr introduced the first angle grinder on the market. The name cut-off grinder for angle grinders is not entirely correct, since cutting grinders are usually driven by a gasoline motor and do not have angular or bevel gearboxes. These machines are, in any case, enormous and are mainly used for track construction. For house and garden use, they are oversized and should not be used. They do not occur in our angle grinder test.

The working principle is the same for all separators. Powered by a motor, a cutting wheel rotates with up to 13300 revolutions per minute (with a diameter of 115 mm). The disc is held on an object cut at a cutting speed of 80 meters per second at the time of cutting different materials; it is mainly the cutting disk. A more detailed discussion of the release agents is given in the later sections. To provide you with the essential information on the types of angle grinders, you will be discussed in detail in the later section. To know more about angle grinder you can read here.

What should you consider when purchasing an angle grinder?

Now that there are many manufacturers of angle grinders and the best models cost less, we want to tell you here, what you should pay attention so that a bad buy can be avoided. In our angle grinder test, it has been shown that such inexpensive devices do not have a real cutting performance and usually belong to the scrap after a few working hours. For this reason, we show you the most important criteria for purchasing such a product. First, you should clarify whether you need a large or small flex. If you only want to cut different metal pieces, e.g., a foundation mat for concrete or metal profiles for drywall construction, a single-handed angle grinder is enough. If you want to slash concrete paths or concrete slabs, you should use a two-handed angle grinder. If you have clarified this question, you can compare the technical details.

  1. Power supply

Usually, most models are network operators and have a standard power cable. Here, of course, the use of a longer cable is recommended for easier operation. Ultimately, however, you have to use an extension cable anyway, so that in the end it does not matter. The one-hand operation also offers the possibility of the angle grinder. The advantage is, of course, that you no longer have to take care of a cable that you can even cut. However, a significant drawback with the battery is that the cut-off grinder is heavier. Also, the general problem with batteries is that they are often empty when you need them. Even with a fast charger, the charge takes half an hour. Therefore, the work may be delayed. In our angle grinder comparison, we had excellent experiences with the battery angle grinder from Bosch.

Battery grinder may certainly have advantages in handling. However, their price is quite high. Therefore, we recommend a little discipline at work and rather buy a more inexpensive flex with power cable. If you ever want to use a two-handed angle grinder, we recommend learning the use of cable-operated models.

  1. Disc Diameter

The disc diameter indicates how strong an object can be cut. The 115 mm separators are only suitable for metal and concrete slabs up to 6 cm thick. A fire wheel with 125 mm creates slightly better values of up to 8 cm. This difference can be decisive, especially for lawns for the garden. The best cutting widths can be achieved with 230 mm discs. Even massive limestones can be dismantled relatively easily. It takes a little bit of skill to set it up, and sometimes it can be an advantage if you first cut it with a smaller flex so that the cut of the significant detachment fits properly.

  1. Power

Performance always plays a significant role in technical equipment. Unfortunately, the rate the more, the better is still widespread. In our angle grinder comparison, it has been shown that for a one-hand angle grinder, a power of 700 watts is necessary.

  1. Idle speed

To compare the actual performance, the idle speed is often indicated. The higher the speed, the faster you can cut through an object. In our test, it has been found that the machines should reach at least 10,000 revolutions per minute if they have a cutting disc with a diameter less than 230 mm. If the diameter is above this, 6000 revolutions should still be possible. If this is not the case, the cutting takes very long and becomes a pain.

  1. Extras

The extras in our angle grinder test were mainly a case and the soft start. The soft start is only required for large angle grinders. It is installed as standard with high-quality products so that you can also put the separator in peace.

  1. Vibrations

Just a chattering bears but significantly to heavier use and handling with the device. Moreover, also the results are not convincing in the course of, especially for the still inexperienced user. So if you are to invest one or two dollars more willing, you should opt for a model that is characterized by its low vibration distinguished. This means that the device in question can be operated quietly or evenly without excessive vibrations during idling, as well as during grinding and cutting.

  1. Cable length

At the time of buying check, the cable length is sufficiently designed. (This point is irrelevant when purchasing a battery-operated model, of course.) In this way, you will benefit the works of more flexibility. Almost every high-quality unit has a so-called spindle, which helps to ensure that the required tool can replace easily and without additional tools manually or with a particular key.

Angle Grinder Accessories

Angle grinders are a good tool to make inappropriate things suitable. But an angle grinder alone is of no avail to you. You need a cutting wheel or grinding wheel. This is the only way to work properly. But which cutting wheel or grinding wheel is now the right one for you?

Angle Grinder Grinding wheel/ Blades/ Discs

The choice of the right disc depends on the application area. Must be something to be separated, then you should by a blade look. There are also different models. For example, conventional cutting discs are used. Do you have to, cut stone or tiles, then one is diamond blade better. This is more resistant and does not cause the stone to burst so much. This allows for finer cuts.

The choice of angle grinder battery is not always easy. Each angle grinder needs electricity. Since it is not connected to the mains, the current must come from the battery. This makes the battery angle grinder portable. Furthermore, handling is improved. This is because no cable can hang around.Unfortunately, a rechargeable battery has not been included with all angle grinders. Therefore you must buy this separately. However, choosing the right battery is not always easy.


  1. The appropriate voltage for the angle grinder 

First of all, you must know the appropriate voltage from the angle grinder battery. This is usually the case with the respective angle grinder on the device. Most batteries are 18 V have. If there is nothing on the angle grinder, you can read the correct voltage in the manual or the packaging. However, manufacturers of angle grinders and accumulators usually pay attention that everything is compatible. That is, for example, a battery of Makita very likely to most Makita fits angle grinders.

  1. Choose the same manufacturer

For the above reason, you will be recommended to choose the battery with the same brand. If you have a Bosch angle grinder, then you should buy a battery from Bosch. First, the search is simplified. Secondly, guarantee claims can be made easier.

Many manufacturers design their accumulators and battery angle grinders so that all batteries are exchanged under the angle grinders. It can no longer happen that, for example, an Einhell battery is no longer suitable for an Einhell angle grinder. This company has a line called Power X-Change invented. Within this family, you can exchange all batteries as you like. All will fit. In Ryobi, these batteries “called One + .”

  1. The suitable angle grinder battery size

How big will be the angle grinder battery? There are many different sizes, but not everyone knows what it means. We from the Angle grinder battery test clear you up. The size of the angle grinder battery is not the dimension, but the load capacity. In short, this means how much of the battery can store energy. This is measured at the angle grinder battery in ampere-hours (Ah). The larger the number, the more power the battery can store. A reasonable size for occasional work is between 2.0 Ah and 3.0 Ah. There are also smaller batteries, but with these, you cannot operate long. If you have to charge the battery all the time, you will quickly lose your motivation. For longer work, we recommend the angle grinder battery test a capacity of at least 4.0 Ah. Only with this size, you can grind for a longer time at a time. Remember, however, that a larger battery also results in more weight. For this reason, you require thinking carefully about which one you want to buy.

  1. The charger for the angle grinder battery

The choice of a charger is quite simple. Each battery has a unique charger that fits. There will be a charger for the Power X-Change batteries, which provides all batteries. Order a charger as soon as you order an angle grinder and battery. You will always need all three components so you can work successfully. Below we have listed some of the most modern battery chargers for you.

How does an angle grinder work?

Comparing the Flex with the traditional grinding wheels or even a “good old” surface grinder, the grinder is not only much faster but also much more flexible. The slices of Flex are a precaution and stocked to (or “intending to”) stability with robust fabric inserts as well as highly elastic resin compounds so that they do not burst at the highest speeds. This high stability in combination with the remarkable flexibility can be sanded or severed by the rapid rotation of different materials. At all, a Flex can master different tasks “in turn.” So You can use it, for example, natural stone, concrete, or metal separation with the so-called grinding discs, most of which are also included modern appliances, welds are cleaned. The polishing of metal surfaces can also be carried out in the same way as the cleansing of surfaces or even the rusting of metals. For most devices, the desired speed.

How to use an angle grinder (Tutorial)

What can be done with an angle grinder?

An angle grinder is designed for different tasks. More expensive units with various disc types are equipped, for example, diamond blades, sanding disc, fur discs and so on. As different as the disc types, the materials that can be machined are so varied. Even the rusting of metal, removing layers of paint, the cutting of stone or the cleaning of welds is possible with modern separation witches readily. Even metal or stone can be “cut” using special corundum discs. Of course, a high quality of the respective grinding wheels must always be taken into account. If these are worn out or even damaged, it is essential to replace them immediately.

For whom is an angle grinder suitable?

The Flex is suitable for almost anyone that has a little technical skill and edits individual surfaces or wants to separate materials. Whether in private or in commercial areas: grinders are for the handyman as designed, as for hobbyists who want to do some grinding or separate activities. Moreover, they are in plastic case professional artisans indispensable. However, non-specialists do well to work carefully and closely and, above all, to take into account the applicable safety regulations.Although the new Flex characterized by their high degree of functionality and the associated considerable workload. However, the related risk of injury is also underestimated.

Advantages and disadvantages of using an angle grinder


  • The processing of various materials is therefore easily and quasi “in no time” possible.
  • Anders, as in the use of the good old grindstone far more is at this moment flexibility and security offered.
  • Also, the work is done quickly.
  • Thanks to the artistic creativity of renowned manufacturers, more and more tasks with the appropriate discs can be achieved with the Flex.


  • A disadvantage of older devices, however, is that gives the high number of rotations of the turntables, wood cannot be machined or only conditionally processed. This is because, during the grinding process, scratches would develop on the surface, which would in some circumstances make the material unusable for further processing.
  • Also, when working with the Flex arise partly high centrifugal forces. Accordingly, care must be taken with the appliance to avoid damage to the machine. Without a particular device holder, especially inexperienced users should not handle it.

What types of angle grinders are available and which one is perfect for you?

When purchasing an angle grinder, you must first choose the right product. You can choose between mini-angle grinders with a 115 mm cutting wheel, regular one-hand angle grinders with a disk size of 125 mm and a two-hand angle grinder with a disc diameter of 230 mm. In the end, you need to know exactly what you want to use your new tool before you buy it.

  1. Single hand angle grinder

The single-handed angle grinders have their names because they have been optimized for use in one hand. One can choose here between mini angle grinders, which have only a 115 mm cutting disc, and regular one-handed flexes slightly larger discs. The latter is more useful from our point of view since even thin concrete slabs can be cut without the need for a great separating hunter. In the course of use, the cut-off wheels become smaller by themselves, so that smaller cut-off wheels must be used automatically at any time. The idle speed is, of course, dependent on the size of the disc. With 115 mm separators, up to 13300 revolutions per minute are achieved. Larger separation hexes produce only 12200 revolutions per minute. In this category, there are now battery angle grinders. While a few years ago the battery power of the devices was rather low, there are now professional models from Makita or Bosch. You can keep up with the network-powered devices. However, they are at least 400 g heavier. It sounds like little, but in the long run, it is quite a big difference. In spite of this, they are much easier to handle because no power cable is required. The manufacturers also use quick-charging devices to guarantee a smooth working day.


  • Small, light and handy
  • Easily cut iron and smaller concrete slabs
  • Relatively cheap


  • Big problems with stronger concrete pieces
  • Turning on should work with both hands since first jerk is relatively strong
  1. Two-handed angle grinder

The two-hand grinders are significantly larger and heavier. Their principle of operation is the same as the one-hand angle grinder. The only difference is the cutting disc with a diameter of 230 mm. The weights of the separation hexes should be between 4 and 5 kg. A slow start also referred to as soft start, is highly recommended for correct positioning. The separators are mainly used in larger construction works. If a concrete floor has to be cut for a shower rail or underfloor heating, they are ideal. Even thicker concrete slabs or masonry stones can be easily cut with them. The significant drawback of the devices is, of course, that they are massive. For this reason, handling and clean-up require little skill.


  • Easily cut iron, stone, and concrete
  • Very much performance
  • Easier start, if soft-start available


  • Difficult and unwieldy

Safety precautions when using an angle grinder

At this point, we would like to tell you the most important safety precautions when dealing with an angle grinder as short as possible so that you do not injure yourself during use.

  • The use of a protective goggle is highly recommended to protect your eyes from sparks and dust.
  • The wearing of flame-resistant cotton clothing is also obligatory so that you do not end up in flames.
  • For protection against falling work, you should wear work shoes with a steel cap.
  • Angle grinders should be held with both hands if possible. One-hand angle grinders should also be used with both hands.
  • For longer periods, and ear protection should be worn due to noise.
  • The protective cover of the appliance must never be removed, as this may lead to increased risk of injury. Do not underestimate the protection of the cutting blade.
  • Rough grinding should only be carried out with special washers and not with simple cut-off wheels.
  • All cutting discs have a shelf life. After expiry of this date, the discs should not be used as they could break or crack.
  • The sparking off an angle grinder should not be underestimated. Unsuitable clothing quickly catches fire. Also, you should look at the place of use carefully. In the case of tiles, there is a risk of burning the sparks. In the bathroom, you should always use a standard iron saw.

The history and development of the angle grinder

Since developing the grindstone, a lot has happened in the tools or machinery industry, in fact. Thus, said grindstone is extremely useful and functional when it comes to grinding various surfaces. However, given its flexibility and stability, it is not particularly well-ordered. Since the invention of this tool already known in ancient times, it was only a matter of time that a further development had to be conceived. The so-called surface grinding was “born.” However, with this device, for example, particularly about the ever-changing world of materials, it was the case that grinding had to be made more and more frequently regarding speed, efficiency, and longevity. The tougher the materials to be processed, the more robust and flexible course also need the wheels to be. Old equipment only partially fulfilled this old requirement. Thus, it was necessary to invent machines which in contrast were characterized by the following factors:

  • A more powerful engine
  • Stable, tear-resistant and break-proof discs
  • More flexible components
  • The ability to process different materials
  • The property, not only to grind but also to separate

Thus, the angle, which is incidentally also known as Schleifhexe, Trenn jager, separating it in 1954 by the company Ackermann and Schmitt, today Flex Power Tools GmbH develops, headquartered in Steinheim a der Murr and brought to market.

The inventor Flex

The name Flex is therefore closely linked to the manufacturer name. Since the invention and the establishment of the Flex, a lot has been done to this day – which one can rightly assert. The stability and fracture resistance of the wheels were almost continuously increased; Additional reinforcements have been introduced, and new connections made of a durable synthetic resin are integrated, changes to the engine reduce the weight, and the handiness is increased. Also, it could be enforced over the years, the resulting in rotating the disks to minimize vibrations to the course of continuously further improved results. These created the best angel grinder for grinder users.

Frequently Asked Questions

For some hurried users, we try to answer the most important questions about the angle grinder as briefly and concisely as possible.

  1. Why are angle grinders used?

Angle grinders are used for cutting stone, concrete, and iron. They have an angular gear that sets a grinding wheel in motion. With the right attachment, walls and floors made of concrete or plaster can also be scraped off. For this purpose, you should use a particular roughing disc. For the processing of rough wood, there are also sanding discs. However, they are usually rarely used.

  1. When was the angle grinder invented?

In 1922 the first grinding machine was developed by the company Flex. The first model was still called MS 6 hand sanding machine. A flexible shaft still drove these first models. It is only at the end of the 1920s that there are angular gearboxes which ensure the rotation of the cutting disc.

  1. What can angle grinder be used to handle claws?

For cuddles such as goats, sheep, and cows, the work can be very strenuous and force-screwed. Especially with mouth disease and foot rot -combating Veterinarians recommend the use of angle grinders. Traditional models with outputs of 600 – 750 watts are used. From our angle grinder test, we can support the price-performance winner of Bosch. He has enough power to cut the claws, but not so much that the animals could become unpleasant from the volume.

  1. What positive aspects does the angle grinder purchase on the Internet?

Many (hobby) artisans still choose to buy an angle grinder at a well-stocked specialist dealer around the corner. However, still turns out repeatedly that the online purchase but in this context substantial benefits offer. Taking only the selection that the regionally based provider in the range, it can be seen quite soon that the web has to offer compared to a huge variety and therefore for each claim, for every need and every budget the right Flex offers. Also, the local supplier is not always specialized in angle grinders and therefore has only a broad range of know-how. Especially with modern appliances but is profound, the in-depth knowledge required – both regarding construction quality, materials, the performance as well as on the areas accessories and spare parts.

In contrast, the whole thing looks different when the Flex is purchased directly on the Internet:

  • In this way, not only does a highly impressive range of offers await you, but also a wide range of additional possibilities (which one might not have considered before).
  • Overall, it is considerably less stressful to shop on the web and to decide for customization of the best device in question thereby calmly. Although you also have to do without the aspect of (personal) advice.

Benefit from cheap rates on the internet

A key advantage when buying online is also the price. Because due to the diversity of providers and the high number of now on the market existing provider it is easy to save money. Namely, while the local dealer is usually considerably more expensive (since overhead expenses, financial expenses for warehousing, rental fees and so on apply), online products are known to be cheaper multiples. Last but not least, the world wide web is usually easier to order accessories or spare parts. Not always these are namely offered locally in stock so that in the search may even longer waiting times and possibly also send to the additional customer costs.

  1. Is the second handle essential?

A second-hand grip is included in the scope of delivery of many cutting grinders. This can be screwed to the side of the angle gear. Even though sanding is often easier with one hand, I find it much safer to hold my machine with both hands when cutting work pieces.

  1. What should I look for when cutting tiles?

When cutting tiles and stoneware, I can only recommend a Flex. With this power tool, cutting work is done very quickly and efficiently. I just have to pay attention to the spark. You should not function the tiles in the bathroom with a flex because the sparks can burn in the remaining tile surfaces due to the high heat. It is better if you go outside to separate.

  1. What are the advantages of a storage case?

I bought a suitable toolbox for my Flex. For some suppliers, this is already included in the scope of supply. Securely safely. A tool or storage case offers the advantage that I can transport my Flex safely securely, but also have the right accessories at hand. In such a case, I can also store a large selection of replacement discs at the same time.

  1. Why is the vibration poor?

A strong vibration characterizes some very inexpensive cutting grinders during the work. This can result from poor transmission quality or a turbulent engine running. This can make the work tough and tiring. Good cut-off grinders are particularly low-vibration. The occurring forces are also derived, among other things, via the private handle holders.

Best Angle Grinder Brands

  1. Flex

The company Flex is the name of the “Flex” or the angle grinder and at the same time as the inventor of this almost indispensable device. Here, it is above all the years of experience that make the products of this manufacturer so unique. However, It should also be that the devices made by Flex are not always particularly small. In contrast to other manufacturers, the original equipment is characterized by a rather high price level. But the fact is that you get an excellent quality for the money, and you will enjoy the Flex for many years.

  1. Metabo

Even devices made by Bosch or Metabo are known for their outstanding quality texture. Even if you also have to squeeze a little deeper into angle grinders for these companies, they are always convinced by the best product quality,

innovations and improvements, customer-oriented service and remarkable guarantees.

  1. Hitachi and Ryobi

Of course, standing Hitachi or Ryobi after facing quality, robustness and durability in nothing. Ryobi is still not very well-known in comparison to the rest of the manufacturers so that the “makers” still strive to “polish” their reputation also regarding angle grinders and, in the course of this, convince by a particularly good customer service.

  1. Makita

Makita is a Japanese Angle Grinder, and in this test, it is provided on this list without question the exotic among the angle grinder manufacturers are. But just because the products come from the Far East, does not suffer the quality. On the contrary, Makita machines are among the best products among connoisseurs. Founded in 1915, Makita is the first company to manufacture and sell power tools. This company targets its products both at home improvement, as well as artisans. Often, the attractive additional equipment at Makita speaks for purchase. So are many products with suitcases and diamond discs sold. The Makita brand was and still is a guarantee of quality. This is also the above-average good ratings at Amazon.

  1. Bosch

Robert Bosch GmbH is an international company of Angle Grinder with more than 130,000 employees. The Group is particularly well-known as an automotive supplier; This share accounts for almost 60% of sales. However, Bosch is characterized precisely by its diverse portfolio of, which also includes power tools such as angle grinders include. Despite the bad headlines around the exhaust scandal of VW, was responsible for its technology Bosch, this company is still for qualitative quality and durable products. In the field angle the brands Bosch and Skil to consolidated. From Bosch, there is only blue angle, but you should not win the Einruck here that all products for professional use are intended. If you are watching for a device for use in crafts, make sure you take the appropriate performance and disk size eighth. The cheap Bosch devices have just a nominal power of 720 watts. This is completely sufficient for use at home, but when cutting hard materials such as metal or iron, the rotational power can subside at increased pressure. Robert Bosch is an innovative company in the cordless field angle right up there. The market for cordless power tools has grown rapidly over the last few years since working with a battery angle grinder is much more comfortable, and the lithium-ion technology is very advanced.

  1. Einhell

The German company Einhell already exists since 1964, when it was founded in Landau. While in the beginning, the company limited itself to electrical engineering, it later devoted itself to the construction of garden tools and instruments. Typical for Einhell are the well-known welding and battery chargers as well as garden grills. The company expanded sharply in the 1970s and 80s and moved its production to Asia in the 80s and 90s. Einhell units are particularly easy to use and possess the highest security measures. Cordless deemed relatively robust so that their power scarcely inferior to grid-connected devices. The delivery is often generous, and spare parts can be obtained quickly and without problems. In particular, the battery units are considered durable and are easy to operate, the battery technology is high and corresponds to the latest generation. Despite these advantages, Einhell products are relatively inexpensive to purchase.


An angle grinder is the thousand among the electrical appliances. Before buying an angle grinder, you should decide for which reason you need to buy an angle grinder. Also, try to match the necessary features that must exist in an angle grinder. If you see all the factors matched well, then you can buy your desired angle grinder.
