Narrow Wheel Dressing – How Thin Can I Go?
To determine what wheel to use, under normal conditions, multiply the grain size by 3.
Example: Grain Size of A 100 Grit Wheel is .0068” x 3 = .0204”

Other conditions such as wheel density will affect how thin a wheel can be made.
For example if you use a more open wheel structure a finer grit size will be required to achieve the same thickness.
