Abrasive Wheel Illustrations Notes.gov

An abrasive wheel that is similar to a Type 1 wheel, but the center of the wheel around the mounting hole is pushed back (depressed). Sometimes called a "depressed center" wheel. It has diameter (D), thickness (U) and hole size (H) dimensions. The depressed center allows grinding on the flat surface of the wheel without interference

Grinding (abrasive cutting) - Wikipedia

A grinding wheel is an expendable wheel used for various grinding and abrasive machining operations. It is generally made from a matrix of coarse abrasive particles pressed and bonded together to form a solid, circular shape, various profiles and cross sections are available depending on the intended usage for the wheel.

As the size of the wheel radius increases, the rim speed increases, despite the face that the motor rpm is the same. If using an oversized wheel, there is a risk that the speed at the rim (peripheral speed) and any centrifugal force becomes so great, that the wheel comes apart. Only use a grinding wheel that is designed for use at a specific RPM.
