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.

Excellent Products and Excellent Service

I recently came across Adam's Bits and was elated to finally find a quality supplier of router end mills not only in Australia but just around the corner! The single flute 1/8" upcut end mill has definitely improved my aluminium processing and I am now getting nice chip sizes on my small hobby machine passes. I have also purchased some downcut and straight edge bits and the downcuts have revolutionised my acrylic machining. He even personally drove to my house and delivered me some bits on a public holiday which allowed me to get a head start on a project. He didn't even mind that I answered the door in my underwear and was hungover to within an inch of death as he laughed and handed me the bits. Very happy to have found Adam and will continue to utilise his wonderful products and services.
