Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. Made from cobalt high-speed steel with a TiN coating, this tap handles demanding materials including alloy steel, stainless steel, and hardened steel. The bottoming chamfer — 1 to 1.5 chamfered threads — allows threading close to the bottom of a blind hole. Overall length is 2.375 inches with a shank diameter of 0.194 inches. It carries a Class 3B fit and H4 thread limit for precision thread production.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for machining and fabrication applications requiring tight-tolerance 10-32 UNF threads in blind holes across a range of materials: alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Typical applications include component manufacturing, tooling fabrication, and precision assembly work where thread integrity and pull-out strength are critical. The right-hand thread direction and bottoming chamfer profile make it appropriate for short blind hole depths where a plug or taper chamfer would leave unthreaded material at the bottom.\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\u003eCobalt HSS construction provides heat and wear resistance in tough materials including hardened and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life across repeated use\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (1 to 1.5 threads) allows threading to near full depth in blind holes\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit and Class 3B fit for precision, close-tolerance thread production\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 32 threads per inch UNF form compatible with standard 10-32 fastener applications\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 workpieces requiring 10-32 UNF internal threads.

Apply appropriate tapping fluid or cutting oil for the workpiece material before tapping. Secure the workpiece fully before operation and use a calibrated torque-controlled tapping driver or CNC tapping cycle to avoid tap breakage. This tap is intended for use by qualified machinists or toolroom personnel familiar with thread forming processes.\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 Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5\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: 0.492 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\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\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 (14001)\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: 1400120005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737112379698,"sku":"1400120005","price":38.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f0ad0ad7ebc65e5f103c1c012e655ae.jpg?v=1788784441","url":"https:\/\/voomisupply.com\/products\/osg-1400120005-thread-forming-tap-10-32-unf-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
