At 8-32 UNC with a bottoming chamfer and 1 to 1.5 chamfered threads, this tap is built to thread close to the bottom of a blind hole. The cobalt construction and bright finish give it durability and heat resistance for demanding tapping applications. With an overall length of 2.125 inches and a tapping depth of 0.752 inches, it is sized for precision work in production and job-shop environments. Licensed machinists, tool-and-die makers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading in a range of metallic workpiece materials. Rated for use in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum, it covers the most common materials encountered in machining and fabrication shops. The right-hand thread direction and H5 thread limit make it well-suited for standard UNC threaded fastener fits in tight-tolerance assemblies. It is sold individually and fits standard tap holders and drive chucks compatible with the 0.168-inch shank diameter and 0.131-inch square drive size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces rather than cuts material, producing stronger threads with no chips\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer with 1 to 1.5 chamfered threads allows threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides elevated heat and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit supports close-tolerance UNC thread fits\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 32 threads per inch, 8-32 UNC specification\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup in standard machine tool environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in blind hole threading applications across alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces.

Power down and secure the workpiece before beginning. Use a recommended tapping fluid or cutting oil matched to the workpiece material to reduce friction and extend tap life. A calibrated torque-limiting tap adapter is strongly advised to prevent tap breakage in hard materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\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: 0.015 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: 1400114100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753813606706,"sku":"1400114100","price":30.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/990aec40545ccc967fe0b01b38ab98be.jpg?v=1788940954","url":"https:\/\/voomisupply.com\/products\/osg-1400114100-thread-forming-tap-8-32-unc-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
