Description:
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 sharper 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 machines, 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.
