Adding to cart… The item has been added

There is only really one bit that you would want to attempt on plastics and that is the 1 flute up cut. Also know and single or “O” flute, the one toothed up cutter allows for maximum chip ejection compared to any other bit and generates the least amount of heat. The combination of the two means that when cutting plastics, you avoid the nasty occurrence of “chip rewelding” where plastic upon cutting heats up to the point it solidifies behind the cutter, rather than ejecting nicely. As these bits are purposely aggressive, using these bits on laminated woods like ply or softwoods would tear up your material and leave a heavily burred finished.

Suitable for

  • Plastics (ABS, acrylic, HPDE etc) 
  • Wood (MDF, hardwood)

Adam’s Tips

To reduce rewelding, ensure your bit doesn’t heat up by driving your feed rate high and router RPM low.

    Good for Polycarbonate

    Posted by Jason on 2nd Apr 2024

    I've been using a variety of sizes in this bit to cut and machine polycarbonate sheets up to 12mm thick. Ramp up the speed and get great chip ejection with very little heat.
