Spiral Flute Tap: 7/16-20, UNF, 3 Flute, Semi-Bottoming, 2B & 3B Class of Fit, Powdered Metal, Steam Oxide Finish MPN:TT97567

This spiral flute tap with dimensions of 7/16-20 UNF is an efficient tool for cutting through hard metals such as steel or stainless steels while producing minimal chips, thanks to its triple chip design that ensures faster chip evacuation and less resistance when cutting. The tap's semi-bottoming feature allows it to leave a smaller chamfer in blind holes for increased accuracy with assembly requirements . Being made of powdered metal increases the strength of the taper allowing it to stay sharp longer and have superior wear resistance during use, while its 3B finish ensures smooth threading operation with minimal scratches that may harm the surface finish of mating threads.
