I Cut a circular pocket in some acrylic for a part I was making it worked flawless great product

only used one, cut 3 types of plastic pleased with the result

Unfortunately they have a short life. I had a bunch of 0.25" X 24" x 24" ABS plastic sheets to engrave for signs on my CNC machine, I'd tried a bunch of different bits by different makers.. all of them would technically work but would leave so much melted plastic shards at the bottom of the letters that I would spend about an hour on each one cleaning them out with an 1/8" chisel. These produced signs that had smooth bottoms to the letters with NO melting. I got about 2.5 hours of CNC cutting before there was some build up of little melted black plastic shards at the bottom of the letters.. still it won't take take more than about 15 minutes per sheet to clean after 4 hours of cutting (compared to an hour each to clean before).. each takes about 1/2 hour to cut. So it works out to about four dollars to save an hour of additional labor if you don't want to have to cleanup any melted bleach... (technical term) that looked a lot like pellets of mouse poop. For me that's worth it - but I can't help feeling if the quality of steel used was better I should have gotten much longer out of it. but maybe that's just the cost of Zero Flute.. sounds very Zen .. If you run a zero flute in the woods and no one is there to hear it, does it make a sound?

Great bits! Exactly what I ordered. I use them for cutting 1/8" aluminum and they work like a charm.

This work good for cutting vinyl records.

The media could not be loaded. This this thing works great 👍🏼 can’t believe it

Worked perfectly. Great value.

They cut very good. Price is very good

Cut acrylic like butter and leave a smooth edge. 2000/mm min 3mm per pass. No burning or melting.

Works really well on acrylic sheets cuts like butter

Works very well in our shop CNC! No issues to report.

I used to use much more expensive bits but after experimenting with these i am hooked. last about as long but a much better price.
