Upcut spiral clears chips fast and provides perfect bottom surface. Use on CNC and other automatic routers as well as hand-held and table-mounted portable routers.
After using these Industrial and Scientific router bits, I was thoroughly disappointed. Although they had a decent cutting speed, the build quality was subpar. The bits looked worn out after just a few uses .The only pro is that they come in a variety of sizes. However, the cons outweigh any benefits. Save your money and invest in a higher quality option..
Pros
Durable and long-lasting due to its carbide material
Cons
Not suitable for intricate or detailed cuts due to its larger flute spiral size
I use this on my CNC router, primarily for cutting 1/8" acrylic mirrors. This cutter broke after about 1200" of cutting. I have brand bits Used Onsrud in the same router that has been cutting (maybe 100,000 inch cut) at the same feed rate for months. Very disappointing.
