About Lapping Discs
Flat laps for slabbing, flat work, faceting prep and finishing — 6" through 24".
- Nickel bond — hardest cutting action, best for fast flattening and roughing.
- Resin bond — softer, leaves a smoother surface, made for the mid and fine steps.
- Sintered discs for long production life.
- Silicon carbide and Mylar discs as the low-cost route through the grit sequence.
- Magnetic-back and 1/4"-20 screw-back mounting; steel master laps, acrylic laps and organizers to carry them.
- Felt and leather discs for the final oxide or diamond polish.
- 6" and 8" for benchtop laps; 10", 12", 14", 16", 18", 20" and 24" for large machines.
- Discs work as a sequence: coarse to flatten, medium to erase the coarse scratches, fine to polish. Skipping a step costs you time, not saves it.
