Spiral Flute Tap: 5/16-24 UNF, 3 Flutes, Modified Bottoming, 3BX Class of Fit, Cobalt, Oxide Coated MPN:BU456011.5044

The Spiral Flute Tap features three flutes for a smoother cutting action and faster removal of chips during thread creation, with modified bottoming design preventing damaging the bottom of the hole when starting a new thread. The 2BX fit class provides improved surface finishes on tapped materials ensuring accurate fitting standards in tight tolerance applications requiring precision machining. This tap is made from cobalt providing superior strength and wear resistance compared to carbon steel alternatives, making it ideal for demanding industrial or aerospace environments where durability under harsh conditions are necessary. Additionally, the oxide coating on its surface reduces friction while cutting threads prolonging tap life significantly and reducing costly replacements over time.
