MACHINTEC PCB drills with carbide (tungsten steel) material with high hardness high wear resistance high strength
Specification: Material: Hard alloy (tungsten steel) Size: Various, use the drop down box above for the size you require Shank Diameter 3.175mm approx Suitable for circuit boards, electronic SMT mold metal processing PCB CNC telecommunications, watch & clock repairs 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
Package include 10pcs PCB CNC drill Bits Please Note The plastic collars can vary in colour but the sizes will be correct
