3M™ General Purpose Depressed Center Wheel, T27, 4-1/2 in x 1/4 in x 7/8 in, 24, 10/Carton, 40 ea/Case

3M™ General Purpose Depressed Center Grinding Wheel is a heavy-duty wheel designed to be used at the beginning of a project; as a grinding wheel, it's often the first step in a sequence. Use this wheel for rough grinding applications like beveling, slag removal, weld grinding and edge work on a variety of metals.

Abrasives made with aluminum oxide mineral which delivers excellent durability, cut and a long service life. Aluminum oxide continually reveals fresh cutting edges on the surface of the disc ensuring extended high performance and real productivity benefits.

Type 27 grinding wheels should be used with an approved grinding wheel guard. it's important the disc not extend beyond the lip of the guard, because the guard helps prevent debris from flying and injuring operators. The depressed center on Type 27 wheels enable flanges or metal attachment systems to recess within the wheel. When depressed center wheels attach to the tool, these attachment systems will not gouge the substrate or inhibit performance.

A grinding wheel must be run on a right angle grinder with a wheel guard that is designed specifically for the size and type of wheel used. The grinding wheel must have a listed maximum operating speed greater than or equal to the maximum listed speed of the grinder used.

Altogether, the 3M™ General Purpose Depressed Center wheel is a durable wheel designed to tackle some of your most aggressive grinding applications.
