Carbide Micro Drill Bit Set 1 Perfect tool

10Pcs PCB Print Circuit Board Carbide Micro Drill Bits Tool

0.3 to 1.2mm for SMT CNC 10pcs/set

Drill has a large scraps discharge space, little resistance and smoothly during the scraps discharge.
Use high quality materials and fine grinding process makes bit more sharp cutting edge, reduce cutting force and broken drill, improve the quality of hole wall.
The cutting edges strictly avoid partial hole, ensure the quality.

Long life, it can drill 2000-5000 pcs under normal working conditions, also can return grinding 4-5 times
Shank diameter : approx. 1/8” (3.175mm)

-Adopt with carbide (tungsten steel) material, with high hardness, high wear resistance, high strength, anti-bending, anti-brea

-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.

Specification:
Material: Hard Alloy (Tungsten Steel)
0.1 to 1.2mm for SMT CNC 10pcs/set
Suitable for: Circuit Boards, Electronic, SMT, Mold, Metal Processing, Telecommunications and Other Industries
Can be used for drilling iron, glass fiber, etc.
