Unlike cutting taps, thread forming taps displace material rather than cut chips, producing stronger threads with no swarf to remove. The tap is constructed from cobalt high-speed steel with a steam oxide coating, giving it good thermal resistance and lubricity for demanding materials. The bottoming chamfer — 1.5 to 2 threads — allows threading close to the bottom of a blind hole. Right-hand thread direction and an H3 thread limit produce a Class 2B fit suitable for general fastener applications.\u003c\/p\u003e\u003cp\u003eThis tap is suited for precision machining operations in job shops, tool rooms, and production environments where small-diameter blind hole threading is required. The cobalt construction supports use in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. Its compact geometry — an overall length of 1.6913 inches — makes it appropriate for use in CNC machining centers, drill presses, and tapping heads where limited clearance is a factor. No coolant-through capability is required, making it compatible with standard tapping setups using flood or hand-applied cutting fluid.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (cold-forming) design produces chip-free, stronger threads in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating enhances lubricity and reduces galling during the forming process\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1.5 to 2 threads) enables threading to near the bottom of a blind hole\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for consistent Class 2B fit\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, standard for the vast majority of threaded fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Secure the workpiece and ensure the tap is driven square to the hole axis to avoid thread misalignment or tap breakage. Use an appropriate tapping fluid or cutting oil for the workpiece material, especially with stainless and hardened steels. When using in a manual tapping handle, apply steady, consistent pressure without forcing the tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0-80\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: 80\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: 1.5 to 2P\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: H3\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\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6913 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3173 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.3500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 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\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 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: 1400100101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733686714674,"sku":"1400100101","price":35.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc60f433ab4d687d909592988f64b852.jpg?v=1788758174","url":"https:\/\/voomisupply.com\/products\/osg-1400100101-thread-forming-tap-0-80-unf-bottoming-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
