PCB drill bits are made of cemented carbide (tungsten steel) material, which has the characteristics of high hardness, high wear resistance, high strength, bending resistance, and fracture resistance.

It is suitable for circuit board, electronics, SMT, mold, watch repair, metal processing, telecommunications and other industries, and can be used for drilling iron, glass fiber, etc.

Extraordinary cutting edge sharpness: Thanks to nanotechnology and advanced grinding technology, the cutting edge is sharper than before, which can reduce cutting force, reduce drilling rate, and improve hole wall quality
