Specifications: Cutting edge diameter (CED): 4.4mm / 0.173"; shank diameter: 3.175mm / 1/8"; overall length: 38.1mm / 1-1/2"; angle point: 165 degree.
Long Tool Life: Made from tungsten carbide, high hardness, high wear resistance, high strength, resistance to bending, anti-impairment, long service life.
Spiral Flute Bits: Spiral flute drill bits reduce cutting force and prevent drill broken, improve the drilling accuracy. Large drill bit chip space, chip resistance, chip smooth, small drilling heat.
Precision: With sharper cutting edge, milling groove and clean surface, the carbide PCB drill bits can work quickly and cleanly, no glitches or scrap left.
Applications: Great for PC boards, plastics, fiberglass, wood, soft metals. Suitable for PCB drilling machines, engraving machine, CNC and high precision special drilling equipment.
