The DZ Spheres are the latest innovation in metal bond diamond tooling.

The unique spherical shape of the diamond combined with the Scientific Polishing Cutter allows us to reach maximum refinement faster than ever before without having to gouge and damage the substrate. Removing stock without having to waste time and money chasing scratches, now that’s smart.

Every slab is different and we should always approach each new slab with a scientific method of measuring the hardness, but through testing and on-the-job studies we have been able to transition from 30# Dz Spheres to 299# Dz Spheres by utilizing Cutter and the unique cutting pattern of the Dz Spheres, taking production to a whole new level while still producing a slab with Ra’s as low as 70 uin.
