Sized for 5\/16-24 UNF threads with a bottoming chamfer of 1 to 1.5 thread pitches, this tap is suited for blind hole threading applications where full thread depth close to the bottom of the bore is required. Constructed from powdered metal high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, it delivers extended tool life and improved wear resistance across a range of workpiece materials. Right-hand thread direction, Class 3B fit, Thread Limit H5.\u003c\/p\u003e\u003cp\u003eThis tap is used in production and maintenance machining environments where blind hole threading is performed in materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The thread forming process displaces material rather than cutting it, resulting in stronger thread forms and no chip evacuation concerns. It is well suited for CNC machining centers, drill presses, and tapping fixtures in both job shop and manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) design eliminates chip evacuation issues in blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal high-speed steel construction for improved toughness and wear resistance over conventional HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1 to 1.5 thread pitches) allows threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eClass 3B fit with H5 thread limit ensures precise, consistent thread tolerance\u003c\/li\u003e\n\u003cli\u003eCompatible with alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading applications in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the pilot hole diameter is sized for thread forming, which typically requires a larger hole than a cutting tap of the same thread specification. Secure the workpiece and use a tapping fixture or floating tap holder to maintain alignment and prevent tap breakage. Power down or de-energize any machine spindle before manually inspecting or changing the tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5 pitches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: 0.059 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1405009508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732908310834,"sku":"1405009508","price":82.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/219f7caf0165a9628c75181e385a2c0c_c3d8d464-7b93-404d-ba9d-f9e632b9ab13.jpg?v=1788748675","url":"https:\/\/voomisupply.com\/products\/osg-1405009508-thread-forming-tap-5-16-24-unf-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
