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.
- Plastics (ABS, acrylic, HPDE etc)
- Wood (MDF, hardwood)
To reduce rewelding, ensure your bit doesn’t heat up by driving your feed rate high and router RPM low.

Very happy with the purchase they work perfectly nice cuts definitely buy them again. Regards Thomas
So I got 2 of these cutters in order to profile cut 40mm Acrylic sheet. I am still using the first. The machine has a Z axis mostly made of licorice so am unable to push this cutter like I would normally on my other milling machines. It is running 10K rpm @ 1300mm/min and has cut over 650 LM to date and the cut on my index finger tells me it is still sharp. With 50mm hanging bellow the collet and making full depth finishing and spring passes the cutter leaves a finish better than I expected Good tool; Highly recommended
These End Mills are great value!
I’ve used this bit to cut corian with some default feeds and speeds (taken from another bit vendor) and it cuts like hot knife through butter. Strongly recommend.
We use these cutters a lot to cut plastics and they perform great!
great for acrylic even in climb milling
Great Bit, did what I had hoped and more.
great finish on polycarbonate excellent service and fast delivery as always from Adam
The bits are super sharp. Cut cleanly and arrived in record time. Thanks
