Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger, smoother threads with no chips to clear. This tap is manufactured from powdered metal high-speed steel and finished with a TiCN (titanium carbonitride) coating to extend tool life under demanding conditions. It carries a 10-32 UNF thread form with a bottoming chamfer of 1 to 1.5 threads, making it suitable for tapping close to the bottom of a blind hole. Class of fit is 3B with a thread limit of H4. Machinists and tooling technicians in production and job shop environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading blind holes in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces. The bottoming chamfer design allows thread engagement very close to the bottom of a drilled hole, which is critical in applications where thread depth is constrained by part geometry. It is part of the OSG EXOTAP VP-NRT series, engineered specifically for form tapping in difficult-to-machine materials. Right-hand thread direction is standard. Typical applications include precision machined components in aerospace, automotive, and industrial manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and increases wear resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003ePowdered metal high-speed steel construction provides toughness and hardness uniformity\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (1 to 1.5 threads) allows tapping close to the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit and 3B class of fit for precise thread 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\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Apply appropriate tapping fluid or cutting oil for the workpiece material; dry tapping is not recommended. Secure the workpiece firmly and use a calibrated torque-controlled tapping attachment or CNC rigid tapping cycle where possible to avoid tap breakage. Inspect the pilot hole depth before tapping to confirm adequate clearance beyond the required thread depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 0.8660 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1940 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1520 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.2500 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 (Titanium Carbonitride)\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 (14050)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 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: 1405005708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746513879346,"sku":"1405005708","price":77.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96d3e1d5d11f5b878bc10aacbc3260c6.jpg?v=1788870954","url":"https:\/\/voomisupply.com\/products\/osg-1405005708-thread-forming-tap-10-32-unf-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
