Compatible with: PCB drilling machines, engraving machine, CNC and special high precision drilling equipment.

Carbide rods and tungsten steel rods, with high hardness, high wear resistance and great strength, bending resistance, no deterioration, long service life.
Large bit chip space, chip resistance, smooth chip, little heat when drilling, reduce smudging.
The drill has a large space for fragments to come out, offers little resistance and is no problem with removing fragments.
The use of high-quality materials and fine grinding offer a cutting edge, reduce the cutting and breaking force of the drill, and improving the quality of the entire wall.
Strict symmetry cutting tip: beneficial and effective cuts that avoid having to perform other drills.
