Grinders and polishers

Angle grinders with FUEL ™ motors, created by Milwaukee together with the most powerful REDLITHIUM-ION ™ batteries, can make several times more cuts and also provide several times longer running time. Milwaukee is also the author of the design and manufacturer of POWERSTATE ™ carbonless motors, which offer up to 10 times longer engine life and also provide up to an incredible 60% more machine power and performance . The engines use intelligent REDLINK PLUS ™ technology , which is also from the Milwaukee workshop and is the most modern electronic system on the market, which protects the tool and battery under extreme load against overload and excessive wear and ensures performance optimization.

What is an angle grinder, its use and its history
An angle grinder, also known as a side, disc, carbone grinder, or flex, is a hand-held power tool used for grinding, polishing, but also for cutting. Although the original tools for rigid grinding wheels were originally developed, the availability of a replaceable power source has spurred a revolution in its use with a wide range of cutters and accessories.
Angle grinders can be driven with compressed air, an electric motor, or a gasoline engine. The motor drives the head with a right-angle gear on which a grinding wheel or a thinner cutting wheel, which can be replaced as required, is mounted. Most of the angle grinders usually have an adjustable cover and a side handle for safe, hands-free operation. Depending on the range of their speed, certain angle grinders can be used as grinders using a grinding wheel with a pad or using a wheel. The base system is usually made of hard plastic, phenolic resin, or medium-hard rubber, depending on the required flexibility, which should be carefully considered before starting a specific work.
Angle grinders are a common feature in metal products and construction sites. They are also common in various and countless productions in designs such as mold grinders and table grinders.
Uses: There are many different types of wheels that are used for different materials and operations, such as grinding wheels (diamond wheels), grinding wheels for grinding, grinding stones, grinding wheels, wire brush wheels and polishing pads. The angle grinder has large bearings to counteract the lateral forces generated during cutting, unlike an electric drill, where the force is axial.
Angle grinders are widely used in metalworking and construction work, as well as in emergency rescue work. They are commonly found in workshops, car repair shops and body repair shops. When looking for the right one for the job, there is a large number of angle grinders to choose from. The most important factors when choosing the right grinder are unambiguously the size of the disc and the performance of the motor. Other factors include the power source (pneumatic or electric), revolutions per minute and the size of the mandrel. As a rule, the size of the disc and the power of the hand angle grinder go hand in hand, and with increasing power, the size of the wheel also increases. Disk size is usually measured in inches or millimeters. Common sizes of angle grinders in the United States are 4, 4.5, 5, 6, 7, 9, and 12 inches. As a rule, discs for pneumatic grinders are much smaller. Pneumatic grinders are usually used for light tasks where higher precision is required. It is natural, because pneumatic grinders can be small and light, but still powerful because they do not contain a heavy copper motor winding, while with the design of an electric grinder it is more difficult to maintain sufficient power at smaller dimensions. Electric grinders are more commonly used for larger and heavy work. However, the exception confirms the rule, and as you can choose a smaller and more powerful grinder from some manufacturers from electric grinders, you will also find large-pneumatic grinders on the market.
Safety: Through a study of sound pressure and vibration levels carried out by the National Institute for Safety and Health at Work, the grinders in the unloaded state ranged from 91 to 103 dBA. In addition, angle grinders create sparks when cutting ferrous metals. By-products can also be flying shards cutting other materials. The blades themselves may also break. This poses a great danger, especially to the face and eyes, as well as to other parts of the body. Therefore, it is necessary to wear a full face shield and other protective clothing. Angle grinders should never be used without the cover or handle attached; they are there as a necessary precaution. All machined materials should be securely clamped or held firmly in the vice.
History: The angle grinder was invented in 1954 by the German company Ackermann + Schmitt (FLEX-ElektrowerkzeugeGmbH) in Steinheim an der Murr. For this reason, the angle grinder in German, Dutch, Slovak, Czech, Polish, Croatian, Latvian, Romanian, Hungarian and Bulgarian is colloquially called "flex". It is also known in Polish as "kątówka" or "gumówka" (= rubber thing), as far as the flexibility of certain types of discs is concerned. However, they are never made of real rubber due to the risk of fire. In Russian known as "болгарка" (literally "Bulgarian"), because the first tools in the USSR were made in Bulgaria.
Milwaukee Grinders: Milwaukee®, the market leader in power tools, invests heavily in improving its uncompetitive cordless tools, bringing countless innovations and technologies to make it easier and easier for professionals and avid amateurs alike. about any demanding project.
