Built from vanadium high-speed steel and finished with a titanium nitride (TiN) coating, this tap handles demanding threading operations where tool life and chip evacuation are critical. The 45-degree helix angle drives chips up and out of the hole, making it well-suited for blind and through-hole applications in tough materials. Coolant-through capability supports high-production environments where heat buildup shortens tool life. Overall length is 7.87 inches with a shank diameter of 0.896 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use by machinists, tool-and-die makers, and maintenance technicians threading holes in alloy steel, carbon steel, cast iron, aluminum, die steel, hardened steel, and stainless steel. The modified bottoming chamfer allows threading close to the bottom of a blind hole while still providing enough lead to start cleanly. The 3-flute spiral design provides balanced cutting action and reliable chip removal across a range of CNC and manual machine setups in both production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form with 2B class of fit for standard tolerance threaded assemblies\u003c\/li\u003e\n  \u003cli\u003e45-degree right-hand spiral flute for efficient upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces friction when threading abrasive or hard materials\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction provides wear resistance across a broad material range\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-feed production threading operations\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer enables threading close to the bottom of blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 1\/2-13 UNC holes to a 2B class of fit in alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap. Use an appropriate cutting fluid or coolant matched to the workpiece material to prevent galling, especially in stainless steel and hardened steel applications. Do not reverse the tap abruptly in blind holes without verifying chip clearance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.87 inches (110 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.614 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 2.252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.896 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\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.124 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: 2332405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734742401330,"sku":"2332405","price":152.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5aec9459cd10069756330923a7bc2663.jpg?v=1788766456","url":"https:\/\/voomisupply.com\/products\/osg-2332405-spiral-flute-tap-1-2-13-unc-tin-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
