Built from High-Speed Steel-E-PM (powder metallurgy HSS) with a TiN coating, it delivers extended tool life in demanding materials including stainless steel. The tap features a plug chamfer for gradual thread engagement and three flutes for efficient chip evacuation forward through the hole. With an overall length of 2.721 inches and a thread length of 0.709 inches, it fits standard tapping chucks and CNC rigid-tapping setups. Machinists, tool-and-die workers, and maintenance technicians use this tap where precise 2B class of fit threads are required in through-hole configurations.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading in ferrous and non-ferrous materials, with a stated material application of stainless steel. The TiN coating reduces friction and resists built-up edge, making it effective in production environments where tool changes slow throughput. It carries an H3\/H4 thread limit designation, which is appropriate for standard 2B tolerance threading in UNF fastener applications. The 5\/16-24 UNF thread form is common in precision mechanical assemblies, automotive components, and structural fastening applications where fine thread engagement is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, keeping flutes clear during through-hole operations\u003c\/li\u003e\n  \u003cli\u003eHigh-Speed Steel-E-PM substrate provides toughness and wear resistance beyond standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating lowers friction and extends tool life in stainless steel and similar materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3-5 thread lead allows gradual entry and reduced torque at start\u003c\/li\u003e\n  \u003cli\u003eH3\/H4 thread limit ensures consistent 2B class of fit across production runs\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement — compatible with flood coolant or cutting oil at the surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in 5\/16-24 UNF applications.

Always ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap to avoid thread runout or tool breakage. Use an appropriate cutting fluid or tapping compound, particularly when working in stainless steel, to reduce heat and extend tool life. Follow your machine tool manufacturer guidelines and applicable shop safety procedures when setting torque limits and feed rates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\/H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E-PM (Powder Metallurgy HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.721 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.709 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.668 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0417 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9039080079380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728193650994,"sku":"9039080079380","price":46.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8dc58a6102ee0c095303c61539e1162e.jpg?v=1788689291","url":"https:\/\/voomisupply.com\/products\/guhring-9039080079380-spiral-point-tap-5-16-24-unf-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
