Diamond Lapping Film

Diamond cuts more quickly, lasts longer, and leaves a finer finish than other lapping grains. Lap without the mess of pastes and slurries—abrasive is embedded in the surface of this waterproof film. Grit and microns are approximate.

Lapping Film for Aluminum and Soft Metals

This film quickly smooths out soft metal without clogging thanks to its silicon carbide abrasive. And since the abrasive is embedded in the film, there’s no mess like with lapping paste and slurries. Film is waterproof. Grit and microns are approximate.
