Unlike cutting taps, this forming tap displaces material rather than cutting it, producing stronger, burr-free threads. Built from cobalt high-speed steel with a TiN (Titanium Nitride) coating, it delivers extended tool life in demanding production and maintenance applications. The bottoming chamfer style — with 1 to 1.5 chamfered threads — allows threading close to the bottom of blind holes where full thread engagement is required. This tap is part of the OSG HY-PRO NRT series and carries a Class 2B fit with an H5 thread limit.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading operations in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. It is appropriate for both production machining environments and toolroom applications where a right-hand, 10-32 UNF thread must be formed in a blind hole. The bottoming geometry makes it particularly useful in assemblies where fasteners seat near the floor of a drilled or milled pocket. Machinists and toolmakers working with tapping machines, CNC machining centers, or hand tappers will find this tap well-suited to close-tolerance work demanding a 2B fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (cold-forming) design creates stronger threads by displacing material rather than cutting chips\u003c\/li\u003e\n\u003cli\u003eCobalt HSS construction provides heat resistance and durability in tough alloys and stainless steel\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life across high-volume applications\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1 to 1.5 threads) enables threading to the base of blind holes\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and Class 2B fit for precise, consistent thread geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming applications in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring a 10-32 UNF, Class 2B thread form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a specific forming tap drill size — do not use a standard cut-tap drill chart, as the recommended hole diameter differs. Secure the workpiece and use a tapping fluid appropriate for the workpiece material, particularly when working with stainless steel or hardened alloys. Ensure the tap is properly aligned with the hole axis before applying torque to avoid tap breakage or thread distortion. On CNC equipment, verify that the spindle feed rate matches the programmed pitch of 32 threads per inch.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\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: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\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: 2B\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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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: 0.492 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: 0.250 inches\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\u003eMaterial Application\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: HY-PRO NRT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 1400120105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738483228978,"sku":"1400120105","price":38.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90abb4224dce045eff96ac953f9652cc.jpg?v=1788800132","url":"https:\/\/voomisupply.com\/products\/osg-1400120105-thread-forming-tap-10-32-unf-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
