Length drill: 10mm
Total length: 38mm
Shank diameter: 3.175mm
PCB drill with carbide (tungsten steel) material, with high hardness, high wear resistance, high strength.

Specification:
Material: Hard alloy (tungsten steel)
Suitable for circuit boards, electronic, SMT, mold, metal processing,PCB, CNC, telecommunications, watch & clock repairs
Can be used for drilling iron, glass fiber, etc.

Feature:
1. bit chip space is large: small chip resistance, chip and smooth, heat a small drill, drill reduce pollution;
2. 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;
3. cutting edge strictly symmetrical: beneficial and efficient cutting, avoid offset drilling.
