drills kit for 0.2, 0.3 and 0.4mm， 3pcs in a kit
Description:
PCB drill with carbide (tungsten steel) material, with high hardness, high wear resistance, high strength, anti-bending,
anti-breakage, etc.
Specification:
Model: DB-P1
Material: Hard alloy (tungsten steel)
Size: 0.2mm,0.3mm,0.4mm
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.
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.
