PCB drill with carbide (tungsten steel) material, with high hardness, high wear resistance, high strength, anti-bending,anti-breakage, etc.
Material: Hard alloy (tungsten steel)
Size: 0.1-1mm; 0.3-1.2mm; 1.1-2.0mm
Shank Diameter: 3.175mm
Suitable for circuit boards, electronic, SMT, mold, metal processing, telecommunications and other industries Can be used for drilling iron, glass fiber, etc.
- 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.
