Built from vanadium high-speed steel and finished with a titanium nitride (TiN) coating, this tap delivers extended tool life and reduced friction in production and maintenance tapping operations. The three-flute spiral point geometry pushes chips forward ahead of the tap, making it well suited for through-hole tapping. The H7 thread limit provides a controlled fit for standard UNC tolerance requirements. Overall length is 2.5 inches with a thread length of 0.752 inches and a shank diameter of 0.255 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is appropriate for use in both manual and machine tapping setups across job shop, maintenance, and light production environments. It is rated for use in aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, hardened steel, cast iron, high-nickel alloy, and titanium. The plug chamfer style requires a pre-existing hole and is the standard choice when tapping through-holes where chip evacuation in the cutting direction is acceptable. Machinists, tool-and-die makers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces built-up edge on the cutting faces\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel substrate withstands the heat generated in harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit ensures controlled UNC fit across standard tolerance applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual thread lead-in for smooth thread engagement\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies use in standard drill press and hand-tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole tapping of 1\/4-20 UNC threads in aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, hardened steel, cast iron, high-nickel alloy, and titanium workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a tap wrench, tapping head, or CNC spindle rated for the appropriate torque range for the workpiece material and tap size. Ensure the pilot hole diameter is correctly sized per UNC tap drill charts before starting. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve thread finish. Never force the tap if resistance increases sharply — back off to clear chips before continuing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: 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\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 11015\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: 1101510405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733462548786,"sku":"1101510405","price":41.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9e1338af9055b95324be0fb31e8bf9f_23896d57-0e50-49ee-959c-9c04dc601587.jpg?v=1788755648","url":"https:\/\/voomisupply.com\/products\/osg-1101510405-spiral-point-tap-1-4-20-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
