Angle grinder. An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing.Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.
For long straight cuts on sheet metal or for light cut-off work, a standard circular saw is used with a 7 + 1 ⁄ 4-inch cutting wheel. These cutting discs are made just like the smaller wheels of an angle grinder, with resin bonded abrasive material, or are of metal with a diamond-coated edge.
Grinding produces sparks and little fragments of metal, called swarf. To use the grinding wheel it must first be clamped to the grinding machine. The wheel type ( e.g. cup or plain wheel below) fit freely on their supporting arbors, the necessary clamping force to transfer the rotary motion being applied to the wheels side by identically sized ...
A man grinding on metal using an angle grinder, causing a lot of sparks. Grinding is a type of abrasive machining process which uses a grinding wheel as cutting tool. A wide variety of machines are used for grinding, best classified as portable or stationary: Portable power tools such as angle grinders, die grinders and cut-off saws
This allowed the production of flapwheels for use with high speed angle grinders. [note 1] These disks were different in format: flatter, like the original rigid angle grinder disks, and with the flaps arranged in a densely overlapped layout rather than radial. The extra lifetime this gave to the disk allowed their use for stock removal and ...
A surface grinder. A cylindrical grinder. These machines include the: Belt grinder, which is usually used as a machining method to process metals and other materials, with the aid of coated abrasives. Analogous to a belt sander (which itself is often used for wood but sometimes metal).
