It is manufactured from powdered metal and coated with TiCN for extended tool life in tough applications. The plug chamfer provides a gradual cutting action suitable for through-hole threading operations. With 3 flutes and an H5 thread limit, this tap maintains consistent thread geometry and holds tight tolerances for 2B class of fit threads. It is used by machinists and maintenance technicians across metal fabrication, aerospace, and industrial repair applications where conventional high-speed steel taps wear too quickly.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole threading in hardened steel, stainless steel, high-nickel alloys, titanium, and alloy steel. The TiCN coating reduces friction and heat buildup, making it effective at higher cutting speeds compared to uncoated alternatives. The spiral point design pushes chips forward through the hole, making it well-suited for production environments and CNC tapping operations where chip evacuation is critical. The right-hand thread direction and standard UNC form make it a direct fit for most general-purpose 1\/4-20 fastener applications in industrial and precision machining settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating extends tool life in hardened steel, stainless steel, titanium, and high-nickel alloys\u003c\/li\u003e\n\u003cli\u003ePowdered metal substrate provides greater wear resistance than standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips ahead of the tap, improving chip evacuation in through-hole applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer allows gradual thread engagement suitable for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and 2B class of fit for consistent, precise thread production\u003c\/li\u003e\n\u003cli\u003eRight-hand, 3-flute design compatible with standard tapping heads and CNC machine tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 1\/4-20 UNC through-hole tapping applications in hardened steel, stainless steel, high-nickel alloys, titanium, and alloy steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by qualified machinists or toolroom technicians using a standard tapping head, tap wrench, or CNC machine tool holder. Ensure the workpiece is securely fixtured and the tap is properly aligned with the drilled hole before engagement. Use an appropriate cutting fluid or tapping compound for the workpiece material to reduce heat and extend tool life. Follow applicable shop safety procedures and machine guarding requirements when operating tapping equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\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: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 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: Hardened Steel, Stainless Steel, High-Nickel Alloy, Titanium, Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 312TI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 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: 1105611408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743736332594,"sku":"1105611408","price":76.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/411efcc9c022e687d1f2b696677d7d5c_b7f64023-0c87-4616-869d-6b327a636ebe.jpg?v=1788849432","url":"https:\/\/voomisupply.com\/products\/osg-1105611408-spiral-point-tap-1-4-20-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
