Descriptions about Angle Grinder

Angle grinders may be used for removing excess material from a piece. There are many different kinds of discs that are used for various materials and tasks, such as cut-off discs (diamond blade), abrasive grinding discs, grinding stones, sanding discs, wire brush wheels and polishing pads.

The Angle grinder, also known as the grinder or disc grinder, is a type of grinding tool used for cutting and grinding glass steel. Angle grinder is a portable electric tool for cutting and grinding glass steel, mainly used for cutting, grinding and brushing metal and stone.
Common models of Angle grinding machines are divided into 100 mm (4 inches), 125 mm (5 inches), 150 mm (6 inches), 180 mm (7 inches) and 230 mm (9 inches) according to the specifications of the accessories used, and the small-size Angle grinding machines used in Europe and the United States are 115 mm.

Types of Angle Grinder: Angle grinders Compact Angle grinders and large Angle grinders, compact Angle grinders: ultra-light, some with safety rebound switch configuration – to meet the requirements of novice diagonal mill operation; Large Angle grinder: Powerful and suitable for difficult grinding and cutting operations.

The main distinction between the two is that an angle grinder is a handheld, portable tool, whereas a disc grinder is a sturdy piece of machinery. A disc grinder is typically used for precision work on smaller workpieces, whereas an angle grinder is used for rough cutting and grinding.

A cut off tool can only be used for cutting, whereas an angle grinder provides you with cutting, shaping, sharpening, grinding, and other functions. A cut off tool can be easily operated with one hand, while the angle grinder requires both hands.

Angle grinders get their name from the disc’s placement at a right angle to the handle’s axis. A safety guard casing is placed around the grinding discs to protect the worker’s eyes and prevent grinding sparks from striking his face.

The appropriate speed for Angle grinder drilling is usually between 3000 and 7000 RPM. The specific speed should be selected according to the hardness of the material to be drilled and the specifications of the drill. Select a higher speed when the material is soft, and reduce the speed when the drill is large.
First, the choice of Angle grinder drilling speed
As a multi-functional power tool, Angle grinder is widely used in metal processing, building decoration and other fields. When drilling, choosing the right speed is the key to ensure the quality and efficiency of the drilling. Generally speaking, the speed range of the Angle mill is between 3000 and 7000 RPM, which can meet the needs of most workplaces.
The choice of the specific speed should be determined according to the hardness of the material being drilled and the specifications of the drill bit. If the drilling material is soft, such as wood or plastic, the speed can be appropriately accelerated to improve the drilling efficiency of the drill bit. For materials with higher hardness, such as metal or stone, a lower speed should be selected to reduce the wear of the drill and prevent overheating during drilling.
In addition, the size and shape of the drill will also affect the choice of speed. In general, the larger the drill bit, the slower the speed should be to ensure the stability and accuracy of the drilling. For ultra-fine drill bits, the speed should also be reduced as much as possible, so as not to damage the bit due to high-speed rotation.
Second, the Angle grinder drilling precautions
Before using an Angle grinder to drill holes, ensure that the rotational speed is stable. Generally speaking, it is necessary to wait 40 to 60 seconds after starting the grinding wheel, so that the speed is stable before grinding or drilling.
When drilling, stand on the side of the grinding wheel, avoid facing the grinding wheel, to prevent the grinding wheel pieces from breaking and flying out. At the same time, the use of Angle mill should keep hands operation, take protective measures to ensure personal safety.
Due to the high speed of the Angle grinder, the saw blade and the cutting blade can not be pressurized, nor can the hard material exceeding the specified thickness be cut. Otherwise, once stuck, it will cause the saw blade and cutting blade to break and splash, and may even cause the machine to lose control, resulting in serious consequences.
In short, when selecting the drilling speed of the Angle grinder, it should be flexibly adjusted according to the actual situation, and strictly abide by the operating procedures and safety precautions. This ensures efficient, safe and smooth drilling operations.
