It features a plug chamfer for ease of entry and is manufactured from High-Speed Steel-E (HSS-E) with an oxide coating that improves lubricity and wear resistance during cutting. The tap carries a 2B class of fit and an H5 thread limit, producing threads within close dimensional tolerances. Overall length is 3.375 inches with a thread length of 0.94 inches. This tap belongs to the Kennametal T820 series and is suited for right-hand threading operations performed by machinists, toolroom techs, and maintenance mechanics on manual or CNC equipment.\u003c\/p\u003e\n\u003cp\u003eThis tap is designed for through-hole threading in steel, stainless steel, and cast iron workpieces. The spiral point geometry pushes chips ahead of the tap and down through the hole, making it well suited for production threading where chip evacuation is critical. With a shank diameter of 0.367 inches and a neck length of 0.80 inches, it fits standard tap holders and collet chucks used in vertical machining centers, drill presses, and tapping heads in typical shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole threading applications\u003c\/li\u003e\n  \u003cli\u003eHSS-E construction provides toughness and heat resistance in demanding materials including stainless steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and improves tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit and 2B class of fit for precise, consistent thread geometry\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3 flutes for controlled entry and balanced cutting action\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement, suitable for standard tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in steel, stainless steel, and cast iron.
