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.

Great performing plastics bit
After trying a large single flute upcut on acrylic I knew I had to get a smaller plastics upcut for the acrylic letters we produce. It did not disappoint at all, producing nice chips, not melting or welding the acrylic The smaller size meant the table had a better chance at keeping the small shapes held down and the edge finish is perfectly acceptable for jobs. I did a small test flame polishing which came up great and would expect it to come up perfect with a tiny bit of wet sanding prior.

Plastics bit
I ordered this bit to see if it would improve the finish I was getting on acrylic panels. I was so impressed by the quality of the finish I've ordered more plastic bits in various sizes. Very happy.
