Spiral Point Tap: #4-40 UNC, 2 Flutes, Plug, 2B/3B Class of Fit, High Speed Steel, Oxide Coated MPN:1206401

The spiral point tap is an essential tool for machinists, providing the ability to create threads with precision and accuracy. Its #4-40 UNC size ensures compatibility with a wide range of applications across multiple industries. Made from high speed steel, this tap offers superior strength and durability when cutting through hard materials such as stainless steel or hard alloys. The spiral point design allows for smooth entry into the workpiece, minimizing chip buildup while producing cleaner cuts and better threads quality. Furthermore, the 2B/3B class of fit enables excellent mating surfaces finishing by providing consistent tolerance control over component parts alignment to avoid slippage or back-out during assembling. Finally, the oxide coated surface treatment delivers improved wear resistance, increasing this tap's longevity and ensuring that it will stand up to rigorous use.
