Spiral Point Tap: 5/16-18 UNC, 2 Flutes, Plug Chamfer, High-Speed Steel, Bright/Uncoated MPN:TT91761

The LISHUI High Speed Steel (HSS) spiral point tap offers users a 5/16 - 18 UNC thread form with the benefit of having two flutes to facilitate efficient chip removal from deep holes for improved hole finish. Designed for use on soft to medium hard materials such as iron brass bronze, aluminum, and other nonferrous metals this tap can achieve both internal external threads in blind holes. Being made of HSS ensures long lasting durability against wear tear compared to carbon steel while its uncoated condition allows better resistance in cutting oily applications thus perfect fit in automotive aerospace hydraulic equipment repair maintenance settings where threads must look good stay clean throughout heavy use without requiring constant honing/re-tapping processes hence enabling operators achieve faster turnarounds cost savings without compromising on precision.
