This is a 2-pack of the Very Fine grade (20 micron/500 grit) of the 3M microfinishing diamond family. Perfect for hard materials such as semi & precious stones, carbides, cobalt, tungsten, chilled iron, etc. For high-polished finishes, follow up with the varying microfinishing diamond grades.
Uses for Microfinishing Diamond Abrasives include:
For Lapidary & Watch Crystal: Ideal for cutting & shaping stones as well as smoothing out chips. Also removes heavy to fine scratches on watch crystals. For a higher polish on your stones or glass, use the higher microfinishing diamond grades afterwards.
For Carbide Tools: Sharpen router bits, forstner bits, shaper cutters and various other tools & remove chips. The sharper-than-factory finish reduces heat build-up during tool operation.
