Review on TEMO Double CARBIDE ROTARY Diameter by Larry Lackings

Fantastic - had to increase the plasma cut hole stack slightly from 3/8 to 1/2 in 1/4 of the panel. Tried a drill press with HSS-Ti coated step drill bits and they did nothing with the hardened edge after plasma cutting. Put this cutter in a Rotozipper set at 15,000 RPM and it will rip out hardened material with very little force, and once it's past the heat affected zone it'll cut through mild steel REALLY fast! Doesn't even sound stupid, worked just as well on the 40th hole as it did on the 1st hole. Great product at a great price.
