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.

    1 Flute UP CUT Carbide End Mill (for Plastics)

    Posted by Steven McAllister on 9th Jan 2023

    have used several different end mills for cutting out stencils. But the 1 Flute UP CUT Carbide End Mill (for Plastics) is in a class of it's own. Speed, travel and the correct bit, is what's makes a great stencil.

    Single flute for plastics

    Posted by Barry (Bazzer) Poulter on 11th Dec 2022

    I use these bits for cutting everything from Acrylic; pvc ,foam board and Alupanel. By not going too long with the end mill you can push these to very fast feed rates.

    I love Adam's Bits. When I first found them I was like "oh yeah another *yawn* bit supplier", but I soon saved the Catalog, with all its useful information, to my drive for constant reference. The 'Good For', Great For', etc info is so useful. And the bits themselves, NEVER a problem. They seem to last a lot longer than certain other popular brands I've used, and zero breakage. Can't praise the hardware, or service, enough.

    Cuts Acrylic Like Butter

    Posted by Mick Stone on 17th Oct 2022

    I recently purchased on on these bits because I stupidly broke what I was going to use on a project. The bit arrived in two business days and I must say it cuts like a dream. The edges are not quite laser polished quality, but the cutter did a brilliant job. Remember spindle as slow as you can go (12000 for me) and feed rate 1200mm/m. Looking for a chipload around 0.1. Great bit. If you are cutting acrylic, get one of these.
