I have their 35 degree tool kit set and the threader. I still get rough cut threads even at 70, 110, 190 rpm etc. tried 3 different cutting oils and taking .005-.003 then .001 and still rough. They cut accurate but still need filing & sanding to get a finished product. Also starts to round off after 2 or 3 muzzle threadings. I like the tool but not at the price they are asking. Looking for carbide inserts now for it because Im not spending twenty something dollars for an insert that cuts no better at lower speeds when I can get carbide for half that. If they were closer to ten or 12 then yeah but not 30 shipped for one or even 20 if you buy two!!! Good luck and search other options as they are out there everywhere until these folks get realistic on their pricing!

Even though, in the description, it says: "NUMBER OF PARTS: 3" This is price for ONE piece.
