Review on LMT Onsrud 63-701 Uncoated CNC Router Bit - Optimal Diameter by Rob Allen

In my opinion simply the best cutter for cutting acrylic glass. I've tried others and had chips, bird's nests and rough edges. This bit, when run at 15,000 rpm and 80 ipm on my CNC router, gives me peace of mind that I can walk away and eat that sandwich until the cut is done. It leaves what I call anthills of small chips around the cut lines, and when the cut is finished I don't feel any heat build-up. The only complaint I have is that I bought one for $20 with change and a week later when I ordered 2 more the price went up $6 which is over 25% so I'm giving it 4 Stars for price gouging.
