Drill bit set for PCB boards 0,3 - 1,2 mm

PCB drill bits with carbide (tungsten steel) material, with high hardness, high wear resistance, high strength.

Bit chip space is large: small chip resistance, chip and smooth, heat a small drill, drill reduce pollution;

Extraordinary cutting edge sharpness: As a result of nanotechnology and advanced grinding technology, bit more sharp cutting edge than before, can reduce the cutting force, reduce the broken drill rate, improve the hole wall quality

Cutting edge strictly symmetrical: beneficial and efficient cutting, avoid offset drilling.

Suitable for: circuit boards, electronic, SMT, mold, metal processing, PCB, CNC,  telecommunications, watch & clock repairs

Can be used for drilling iron, glass fiber, etc.
