Drill Chamfer Toughness Resistant Tungsten Straight Carbide Spot Drill

Product Description

Solid Tungsten Carbide Spot Drill

Products Description
This is a  point drill bit for drilling pilot holes in hard, brittle materials such as ceramics and quartz glass.

This pilot hole drill bit is for use on hard, brittle materials, so the bit is made with solid carbide, sintered diamond particles with excellent wear resistance. While it is possible to achieve high precision using only the  polygonal angle drill bits we have released, it is possible to further improve the precision and reliability of hole positioning by using our pointed drill bits. The standard sizes for drill bits range from 0.3mm - 3.0mm in diameter in increments of 0.1mm.
