Built from powdered metal and finished with a TICN (Titanium Carbon Nitride) coating, this tap is engineered for demanding threading operations in harder and more abrasive materials. It features a modified bottoming chamfer, allowing threads to be cut close to the bottom of blind holes. The 3-flute spiral design ejects chips upward out of the hole, reducing clogging and improving thread quality in deep or interrupted cuts. Overall length is 2.125 inches, and the shank diameter is 1.21 inches. This tap belongs to the OSG EXOTAP VC-10TI series, known for performance in high-heat and high-wear applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. It is commonly used in precision machining, aerospace fabrication, tool-and-die work, and industrial manufacturing environments where thread integrity and tool life are critical. The modified bottoming chamfer makes it the correct choice when thread depth must extend near the base of a blind hole. A right-hand helix angle of 10 degrees aids chip evacuation in the materials listed above. Machinists and CNC operators working in job shops or production environments will find this tap appropriate for both manual tapping operations and machine tapping with appropriate toolholding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-32 UNC thread form with 2B class of fit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral design promotes upward chip ejection, reducing chip packing in blind holes\u003c\/li\u003e\n  \u003cli\u003eTICN coating increases surface hardness and wear resistance for use in tough materials\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides uniform grain structure and improved toughness over HSS\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent fit in 2B tolerance applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute and thread direction; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. Part of the OSG EXOTAP VC-10TI series (Series 313TI).

Before tapping, verify that the pilot hole diameter and depth are correct for the 8-32 UNC thread specification and the 2B class of fit. Use appropriate tapping fluid or cutting oil for the work material, particularly with stainless steel, titanium, and high-nickel alloys, to reduce heat buildup and extend tool life. Never exceed the recommended spindle speed for the work material, and ensure the tap is properly supported to prevent deflection or breakage.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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\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: 10 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\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 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\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TICN (Titanium Carbon Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Stainless Steel, Hardened Steel, Titanium, High-Nickel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOTAP VC-10TI (313TI)\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: 1305710808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740162752818,"sku":"1305710808","price":74.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_a56b5b3c-4e24-4394-9253-632dda3aa46f.jpg?v=1788823047","url":"https:\/\/voomisupply.com\/products\/osg-1305710808-spiral-flute-tap-8-32-unc-2b-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
