Unlike cutting taps, thread forming taps displace material rather than cutting it, producing stronger threads with no chips to clear from the hole. Manufactured from high-speed steel with a bright finish, this tap measures 3.375 inches in overall length and carries a 1.5 to 2 thread bottoming chamfer. It is suited for use by machinists, maintenance technicians, and tool-room professionals working with ferrous and non-ferrous materials in production or repair settings.\u003c\/p\u003e\u003cp\u003eThe OSG 2867400 is rated for threading aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. It is specifically designed for blind hole threading, making it a practical choice for applications where a through-hole is not possible and full thread depth near the bottom of the bore is required. Right-hand thread direction and a shank diameter of 0.367 inches make it compatible with standard tap holders and chucks used in CNC and manual tapping operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material for stronger, chip-free threads\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1.5-2P) allows full thread depth in blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across multiple applications\u003c\/li\u003e\n\u003cli\u003eBright finish suitable for use with standard tapping fluids and coolants\u003c\/li\u003e\n\u003cli\u003eRight-hand, 1\/2-13 UNC thread standard with 2B class of fit\u003c\/li\u003e\n\u003cli\u003eRated for aluminum, cast aluminum, low-carbon steel, and medium-carbon steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel workpieces requiring a 1\/2-13 UNC, 2B class of fit thread form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is intended for use by qualified machinists or maintenance technicians operating manual or CNC tapping equipment. Always ensure the workpiece is properly secured and the tap is aligned perpendicular to the bore before beginning the tapping cycle. Use an appropriate tapping fluid or cutting oil for the material being threaded to extend tool life and maintain thread quality. Inspect the tap for wear or chipping before each use and replace if thread quality degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\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: 1.5-2P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.921 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.933 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\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: Aluminum, Cast Aluminum, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.126 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: 2867400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738498957618,"sku":"2867400","price":77.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57ea1b80c27895fbb3e9ab2577c70706.jpg?v=1788800307","url":"https:\/\/voomisupply.com\/products\/osg-2867400-thread-forming-tap-1-2-13-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
