10Pcs Print Circuit Board Carbide Micro Drill Bits Tool 0.1mm To 2.0 Mm NEW 0.11mm

Description:

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: 0.3-1.2mm;
Shank Diameter: 3.175mm
Suitable for circuit boards, electronic, SMT, mold, metal processing, telecommunications and industries
Can be used for drilling iron, glass fiber, etc.

Feature:
① bit space is large: small resistance, and smooth, heat a small drill, drill reduce pollution;
② extraordinary edge sharpness: As a result of nanotechnology and advanced grinding technology, bit more sharp edge than before, can reduce the force, reduce the broken drill rate, improve the hole wall quality; ③ edge strictly symmetrical: beneficial and efficient , avoid offset drilling.
