Micro Drill Bit for PCB, Acrylic, Plastics

Tungsten Carbide Tip

Made from ultra-fine grain carbide material for precise and easy experience, high hardness, good toughness, wear resistance, high strength, resistance to bending.

Spiral Flutes

Sharp cutting edge provides smooth cutting, reduces cutting force, prevents drill broken, and improves the drilling accuracy. Spiral chip space design for fast and clean chip removal.

High Precision

With sharp cutting edge, milling groove and clean surface. PCB drill bits have good milling and cutting performance. Can work quickly and cleanly, no glitches or scrap left.

Features

  • Can ensure high work efficiency.
  • Carbide can run at higher speed than high-speed steel.
  • High speed steel shank provide high hardness and good toughness for wear resistance.

Wide Applications

Suitable for drilling and engraving PCB, acrylic, plastics, fiberglass, wood, aluminium, soft metals. Used on PCB drilling machines, engraving machine, CNC lathes, machining center.

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.

Tips

The drill bits are too tiny, so it is very fragile for handling. Use vertically and take good control of your CNC speed. The longer the length of the tool clamped by the chuck, the better. If the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life.

Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
