Unlike cutting taps, this forming tap displaces material rather than removing chips, producing stronger threads with a superior surface finish. Built from powdered metal high-speed steel and finished with a TiCN coating, it delivers extended tool life in demanding production environments. The H5 thread limit ensures close tolerance control, and the modified bottoming chamfer with 2 to 2.5 chamfered threads allows threading close to the bottom of blind holes. Overall length is 2.375 inches with a tapping depth of 0.866 inches. This tap belongs to the OSG EXOTAP VP-NRT series and is suited for machinists and toolroom technicians working in precision threading operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. It is specifically intended for blind hole threading where chip evacuation is a concern and thread strength is critical. The modified bottoming chamfer makes it well suited for shallow blind holes where a standard plug chamfer would leave insufficient full threads at the bottom of the bore. Typical applications include CNC machining centers, manual tapping operations, and production threading in aerospace, automotive, and general manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, producing stronger threads and eliminating chip removal from blind holes\u003c\/li\u003e\n  \u003cli\u003ePowdered metal high-speed steel construction provides uniform grain structure and superior wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5 chamfered threads) enables threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit ensures precise tolerance control for consistent thread fit\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping attachments and CNC rigid tapping cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Apply appropriate tapping fluid or cutting oil matched to the workpiece material before tapping. For CNC rigid tapping, verify spindle synchronization and use the correct tap holder to avoid tool breakage. Secure the workpiece completely before beginning the tapping operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24\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: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\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: 0.4921 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.866 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.152 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 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\u003eCompatible Workpiece Materials\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\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: 0.02 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: 1405005408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739729527090,"sku":"1405005408","price":77.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/219f7caf0165a9628c75181e385a2c0c_b2feee8e-b353-4e85-82aa-a828f435a8dc.jpg?v=1788818289","url":"https:\/\/voomisupply.com\/products\/osg-1405005408-thread-forming-tap-10-24-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
