About this item

  • PCB Drill Bit: Cutting edge diameter: 0.8mm / 0.031"; 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.

Very fragile because they are so tiny.

These appear to be a quality product. For general purposes I have no problem with them however, I purchased them because I need a precise size for a press fit. I ordered 1.45 mm and they measured undersize. I re-ordered and the replacements measure on size.

I was actually surprised by how well these work. It was kind of a learning curve that resulting in breaking 2 bits . However just a dab of cutting oil, slow speeds and VERY lite pressure on the drill press handle I was able to drill through about 1/2 inch into hardened carbon steel sandwiched between 304 stainless. Impressive for a 1mm drill bit.

These are sized correct and work well so far in softer materials

These cut well but you have to proceed very slow and not deep good for circuit boards only or very thin soft metals
