The new Sapphire burnishing tool SBT-120 is indispensable for delicate burnishing of fine instrument parts such as miniature pivot points, shafting, probes etc. Materials can be hard steel, carbide, glass and ceramics. May also be used for deburring of soft and hard materials.

The precision ground Sapphire (ground on all 5 exposed surfaces) is mounted in a non-rolling (won't roll off bench) hexagonal gold anodized aluminum holder. It is sold in a plastic storing and shipping container, one tool per container.
