10pcs Set of carbide Tungsten Steel Drill Bit CNC PCB

0.35mm carbide Tungsten steel Drill Bit CNC PCB Drill Micro Bit

PCB drill with carbide (tungsten steel) material, with high hardness, high wear resistance, high strength, anti-bending,
anti-breakage, etc.

Specification:
Material: Hard alloy (tungsten steel)
Size: 0.35mm
Suitable for circuit boards, electronic, SMT, mold, metal processing, telecommunications and other industries
Can be used for drilling iron, glass fiber, etc.

Feature:
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.

Package include:
10 x  0.35mm PCB CNC drill Bit
