It carries a 12-24 UNC thread form, right-hand thread direction, and is manufactured from powdered metal high-speed steel with a TiCN (V) coating for improved wear resistance and tool life. The overall length is 2.375 inches, with a thread length of 0.4961 inches and a shank diameter of 0.2200 inches. Tapping depth reaches 0.9330 inches, making it well suited for close-tolerance blind holes where a full thread is needed near the bottom. This tap is installed by machinists, tool and die makers, and maintenance professionals working in precision threading applications.\u003c\/p\u003e\u003cp\u003eThis tap is engineered for use in a range of materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. It is best applied in blind hole threading scenarios where a bottoming chamfer of 1 to 1.5 threads is required. The H5 thread limit and Class 3B fit ensure tight dimensional control, making it appropriate for applications where thread quality and consistency are critical. It belongs to the EXOTAP VP-NRT series, which is built around cold-forming rather than cutting, eliminating chips from the threading process.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) design eliminates chip buildup in blind holes\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer of 1 to 1.5 threads for threading close to hole bottom\u003c\/li\u003e\n\u003cli\u003ePowdered metal high-speed steel construction for consistent hardness and toughness\u003c\/li\u003e\n\u003cli\u003eTiCN (V) coating improves surface hardness and reduces friction during forming\u003c\/li\u003e\n\u003cli\u003eH5 thread limit with Class 3B fit for tight tolerance control\u003c\/li\u003e\n\u003cli\u003eCompatible with alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSuitable for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring a 12-24 UNC thread at Class 3B fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a correctly sized forming hole  -  consult published forming tap drill charts for the 12-24 UNC size before drilling. Always power down or de-energize any machine tool before mounting the tap. Use a recommended tapping fluid or cutting oil appropriate for the workpiece material to reduce forming load and extend tool life. Do not exceed the rated tapping depth; overdriving a bottoming tap in a blind hole can fracture the tool or damage the workpiece thread.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4961 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.9330 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1650 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.2813 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\/Finish\u003c\/strong\u003e: TiCN (V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 1405006408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741021634866,"sku":"1405006408","price":80.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7f578c634c35ef27c59a0556a4e8b3b_8338e82a-6905-47aa-b8ce-b3af26879956.jpg?v=1788828923","url":"https:\/\/voomisupply.com\/products\/osg-1405006408-thread-forming-tap-12-24-unc-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
