About this item

  • PCB Drill Bit: Cutting edge diameter: 3.175mm / 0.13"; shank diameter: 3.175mm / 1/8"; overall length: 38mm / 1-1/2". High hardness, good toughness, wear resistance, high strength, resistance to bending.
  • Wide Applications: Suitable for drilling PCB, acrylic, plastics, fiberglass, wood, aluminium, soft metals. Used on PCB drilling machines, engraving machine, CNC lathes, machining center. Use vertically and take good control of your CNC speed.
  • Sharp Cutting Edge: 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. The tool set can work quickly and cleanly, no glitches or scrap left.
  • Tungsten Carbide Tool: Long-lasting bits are made from tungsten carbide for precise and easy experience. Carbide can run at higher speed than high-speed steel. Carbide material with good milling and cutting performance, can ensure high work efficiency.
  • Tips: 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.


Product Description

Tungsten Carbide Material

Made from tungsten carbide for precise and easy experience. Features high hardness, good toughness, wear resistance, high strength, resistance to bending and heat resistance.

Sharp Cutting Edge

Sharp cutting edge provides smooth cutting, reduces cutting force, prevents drill broken, and improves the drilling accuracy.

Spiral Flutes

Spiral chip space design for fast and clean chip removal. Can work quickly and cleanly, no glitches or scrap left. The positioning rings reduce machine adjustment time and increase efficiency.

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.

The mini drill bits is easily twisted off. Use vertically and take good control of your CNC speed.

Tips

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.

Was hoping these would drill better through 8mm bolts , but these were only marginally better than reg Cobolt HSS bits. Snapped 3 on one bolt, others did OK.
