Straight Flutes Tap: 5/16-24, UNF, 4 Flutes, Bottoming, 3B, High Speed Steel, Bright/Uncoated MPN:TT90389

A straight flutes tap featuring a 5/16-24 thread and UNF (Unified National Fine) designation in High Speed Steel construction with four spiral flutes, it comes coated in a standard 3B finish suitable for many different metal applications. The bright and uncoated finish makes it ideal for professional use across multiple industries, while its superior strength ensures a perfect fit on threads each time without fear of wobble or damage during tapping. The four spiral flutes facilitate smoother cuts by continuously clearing away debris whilst providing improved grip within the material being drilled - preventing it from spinning within the workpiece or walking out from underneath. The bottoming feature reduces thread strippage when starting with a pilot hole, resulting in accurate holes for assemblies and increased longevity due to less wear on tap's cutting edge. Overall, this versatile Tap makes light work of a range of materials and tasks requiring precise, repeatable accuracy at an affordable price point.
