Fit and compatibility
This 4-inch cup wheel mounts with 7/8-5/8 arbor, so check that your grinder matches before ordering. It is the single-row version of the 504 turbo family. MK Diamond publishes sister cup wheels in other diameters and mountings under separate part numbers.
Getting the most from the cup wheel
Confirm that your grinder has the matching thread or arbor and that its maximum RPM is within the wheel rating, keep the guard in place, and let the segments cut with light, even pressure. Move the wheel steadily across the surface instead of pressing hard in one spot. Wear eye, hearing and respiratory protection, and follow the grinder maker and MK Diamond safety guidance.
