Cuts well on my Grizzly G0765 (7x14) mini lathe. I almost got 1 star for not having torx screwdrivers, but I already had the correct (very small - T8, IIRC) screwdriver so there wasn't much loss. From the factory they all require a .024" center cut spacer. with a standard tool rack, but I've since switched to a Little Machine Shop quick change tool rack so shims are no longer needed. clean finish (using Tap Magic and WD respectively -40 as coolant.) These are very small insert bits though, so don't try to pull the stuff out.
