  • Product Details

Grinding Wheels with a depressed center design allow the flange/lock nut to recess within the grinding wheel so that it can be used for various grinding and cutting applications. Depressed center wheels are designed to handle the most severe right angle grinding applications from heavy stock removal to rough blending. More recently, depressed center wheels have been designed to increase the utility of the right angle grinder for cut-off applications. While large right angle grinders in 7" and 9" have been around for many years, small or mini grinders that use 4", 4-1/2" and 5" wheels making this machine, and wheel category, one of the most popular in power tool applications.


1111.jpgThe wheels are generally made from a composite material consisting of coarse-

particle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding whe

el terminology) to form a solid, circular shape. Various profiles and cross sections are available depending 

on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with pa

rticles bonded to the surface. Today most grinding wheels are artificial composites made with artificial ag

gregates, but the history of grinding wheels began with natural composite stones, such as those used for 


The manufacture of these wheels is a precise and tightly controlled process, due not only to the inherent 

safety risks of a spinning disc, but also the composition and uniformity required to prevent that disc from

 exploding due to the high stresses produced on rotation.

Grinding wheels are consumables, although the life span can vary widely depending on the use case, fro

m less than a day to many years. As the wheel cuts, it periodically releases individual grains of abrasive, ty

pically because they grow dull and the increased drag pulls them out of the bond. Fresh grains are expos

ed in this wear process, which begin the next cycle. The rate of wear in this process is usually very predict

able for a given application, and is necessary for good performance.
