Customers find the diamond lap disc effective for sharpening tungsten, working well on standard 4-1/2" grinders and being better than a bench grinder.

Center hole is very loose for an angle grinder.
Anthony P.—May 29, 2025✓ Verified purchase
The center hole is not the standard angle grinder hole, it's bigger and does not mount tightly. The material looks decent but I have not used much to know if it will last. Read more

Disk is part of Lathe tooling carbide sharpener
Joe M.—February 17, 2024✓ Verified purchase
Disk is part of Lathe tooling carbide sharpener (on homemade motorized system). The disk plate is steel with what appears to be a chrome coating, upon which the diamond abrasive is applied/fused to one side only. The disk works well with my magnetic retention method and allowed custom enlargement of center hole and notching peculiar to my setup - and still runs true. The diamond surface is holding up well after touching up all my carbide bits, I'm happy. (400 grit tested, 800 grit have but not tested, will try 200 grit next) Yes, I would order again. Read more
