Spiral Flute Tap: 5/16-24, UNF, 3 Flute, Bottoming, 2B Class of Fit, High Speed Steel, Oxide Finish MPN:030082TC

The spiral flute tap is designed for precision threading of metal workpieces with UNF thread size using the 5/16-24 size range. The bottoming style ensures that it creates mating threads suitable for holding fasteners securely in place while minimizing slippage or damage to the threads. With three flutes, it enhances chip evacuation from the cutter, reducing friction and allowing the tap to perform more efficiently by cutting smoothly without binding or overheating. Made of high speed steel, it offers durability and wear resistance suitable for various metal materials including stainless steel, aluminum or steel while its 2B class of fit ensures precision threading results without compromising accuracy. The oxide finish provides a protective layer that reduces friction between the tap and workpiece for smooth cutting action, making it ideal for machinists, toolmakers or hobbyists seeking high-quality, precise threading in spiral flute taps applications.
