Review on CMT 191 007 11 Carbide Spiral Diameter by Gerald Hill

Works very well on my home made CNC router. I use it in a Dewalt 611. I thought I screwed up when I accidentally programmed the machine and it cut a piece fast enough that the wood smoked as it cut. (I didn't notice it until after 15 minutes, so I let it run out.) Aside from the discoloration, however, it hasn't suffered from wear at all. It still looks as sharp as before.
