In order to improve the wear resistance of drill bits, we coat them with diamond.

 The detailed specification of Diamond coated PCB drill bits

Advantages of diamond-coated PCB drill bits

1.  Raw materials are international famous brand tungsten carbide rods and steel bars, or Solid carbide, which will be long tool life and high hardness and high wear resistance and high strength and anti-bending. 

2.  With high precision grinding technology, the cutting edge of the bit is sharper than other bits, which can reduce cutting force, reduce drill breakage rate and improve the quality of the hole wall.

3. The high wear resistance nanodiamond coating ensures that the life of the drill bit is 2-5 times that of the ordinary tungsten steel drill, usually, it can drill more than 10000 holes.
