Angle Grinder

Angle grinder is also called side grinder or disc grinder. It is a portable hand-held power tool used in grinding, cutting and polishing, for metal, wood, stone, tile. Angle grinders use high-speed rotating thin-slice grinding wheels (grinding disks) to grind, cut, rust, and polish materials. It is also a common woodworking tool. Some special angle grinders can be used as sanders once equipped with a sanding disc with a backing pad or disc. It depends on their speed range.

The Difference between Angle Grinder and Die Grinder

The main difference between angle grinder and die grinder is function, size and power. Angle grinders are mainly used for cutting and rough grinding, while die grinder is a rotating tool used for precision machining.

Angle Grinder Selection

• Grinding Disk Size

When buying an angle grinder, the head and grinding disk is one of the first factors to consider. The higher the motor power, the larger the disk diameter should be. Choose a disk with appropriate size according to the material to be polished and the required work accuracy. Common disk size is 4 inch or 4-1/2 inch, and the larger one can be up to 9 inch.

• Rotation Speed

Rotation speed of the angle grinder is measured by revolutions per minute (rpm). Most angle grinder discs rotate 5,000 to 10,000 revolutions per minute. The higher the rotation speed, the higher the work efficiency.

• Handle

Since the angle grinder is a small electric machine, safety must be considered when using it. An angle grinder with an adjustable handle may be the best choice, which facilitates grinding and cutting with both hands. In addition to handle, angle grinder should also have an adjustable protective cover to protect the human body from debris and sparks.
