CoCud PCB Drill Bits, 3.9mm Diameter 1/8" Shank, Solid Tungsten Carbide Precision Drilling - (Applications: for Print Circuit Board CNC Engraving), 1-Piece
- ★ PCB Drill Bits Size --- Cutting edge diameter (CED): 3.9mm / 0.154"; shank diameter: 3.175mm / 1/8"; cutting edge length: 12mm / 0.472"; overall length: 38mm / 1-1/2"; tool flute type: spiral; point angle: 165 degree
- ★ Wide Applications --- Widely used for drilling PCB (print circuit board), acrylic, plastics, aluminium, soft metal, fiberglass, wood, etc. Suitable for PCB drilling machines, engraving machines, CNC and high precision special drilling equipment.
- ★ Sharp Cutting Edge --- Sharp cutting edge provides smooth drilling, low cutting force and drilling accuracy to prevent tool breakage. Large chip removal space, smooth chip removal, and low drilling heat.
- ★ Solid Tungsten Carbide --- It has high hardness, wear resistance, high strength, resistance to bending and heat resistance, providing a precise and easy experience. With good milling and engraving performance, carbide materials can ensure high work efficiency.
- ★ Useful Tips --- The mini drill bit is too tiny and easily twisted off. Be careful and control your CNC speed. The longer the chuck clamps, the better. If the clamping length is short, the feed rate and cutting speed should be reduced to reduce vibration and increase tool life.
