PCB Drill BitsDescription: 1.
Long Tool Life: With high hardness, high wear resistance, high strength, resistance to bending, anti-impairment. Long-lasting bits are made from Tungsten Carbide for precise, easy experience. 2.
Spiral Flute Bits: Tip spiral flute drill bits with shaper cutting edge, reduce cutting force and prevent drill broken, improve the drilling accuracy. 3.
High Precision: With sharp cutting edge, milling groove and clean surface, these sets of tool work quickly and cleanly, no glitches or scrap left. 4.
Great Use: Great for PC Boards, Plastics, Fiberglass, Wood, Soft Metals.
Fit for: PCB drilling machines, engraving machine, CNC and high precision special drilling equipment. 5.
Good Replacements: Carbide PCB Drill Bits replace your CNC machines and any hand held tool. Large drill bit chip space, chip resistance, chip smooth, small drilling heat.
Note: The drill bits are too tiny, so it is very fragile for handling. Please be careful and take good control of your CNC speed.
