Built from powdered metal high-speed steel (PM-HSS) with a TiCN coating, it produces 5\/16-24 UNF right-hand threads using a bottoming chamfer with 1 to 1.5 chamfered threads. The bottoming profile allows threading close to the bottom of blind holes. An H8 thread limit provides controlled tolerance for precision thread production. Machinists and toolroom technicians use this tap in CNC machining centers, drill presses, and tapping machines where chip-free internal threading is required.\u003c\/p\u003e\n\u003cp\u003eThe 1405009808 is suited for blind hole threading applications across a broad range of workpiece materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. Its cold-forming action displaces material rather than cutting it, which typically results in stronger thread forms and longer tool life compared to cut taps. This makes it a practical choice for production threading in automotive, aerospace, and general machining environments where thread integrity and cycle time matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer with 1 to 1.5 chamfered threads for threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003ePowdered metal high-speed steel construction for improved wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eH8 thread limit for consistent, tolerance-controlled 5\/16-24 UNF thread production\u003c\/li\u003e\n  \u003cli\u003eCold-forming process eliminates chips, reducing tap breakage risk and improving thread strength\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Use a suitable tapping fluid or cutting oil appropriate to the workpiece material; forming taps generate higher torque than cut taps and lubrication is critical. Secure the workpiece firmly and ensure the tap is driven perpendicular to the work surface to avoid thread distortion. Verify tapping machine or driver torque limits before use to prevent tap breakage.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.719 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.6654 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.126 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\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: EXOTAP VP-NRT (Series 14050)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1405009808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739446477106,"sku":"1405009808","price":90.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7f578c634c35ef27c59a0556a4e8b3b_b243ae57-8a95-4357-bdc1-5d071a7ff337.jpg?v=1788814695","url":"https:\/\/voomisupply.com\/products\/osg-1405009808-thread-forming-tap-5-16-24-unf-bottoming-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
