- Petrograd Diamond Lap - 150 Grit
Designed for lapping, grinding and finishing polishing of products made of hardened, case hardened and alloyed steels, glass, stone, superhard ceramic and other hard materials.
The densely packed industrial diamonds are vacuum welded to the surface of the bar for maximum service life.
As always with diamonds, plenty of water based cutting fluid, light pressure and lots of movement are the key to good results. Avoid using on soft materials like brass, bronze, aluminium or soft iron which will gum up the surface.
