Grinding and Polishing Laps for the CutKit (6 inch laps)

These are cutting and polishing laps for the CutKit™.  These are 6 inch diameter toppers which are placed on the master lap and locked down.

100 grit laps are good for extra-coarse roughing of very large stones like dice.

240 grit laps are good for coarse shaping of a stone.

600 grit laps are used for placing facets close to their final position.  These laps should be broken in with a piece of corundum, as they will typically cut a little too aggressively when fresh.

Copper laps are charged with diamond grit (best of all, Gearloose™ Diastiks) and used for prepolish and polish.  These sometimes arrive with scratches--don't be concerned, they come from the factory that way.  Copper laps tend to perform best when scored, putting intentional scratches into the surface to help retain diamond and increase surface complexity.  Here is a video on the topic by Justin K Prim.
