It cuts a 1\/2-13 UNC thread profile using a three-flute, right-hand spiral point geometry that pushes chips forward ahead of the cutting zone, keeping the flutes clear and reducing the risk of chip packing. Built from high-speed steel with a bright, uncoated finish, this tap suits manual and machine tapping applications where a standard H3 thread limit and 2B\/3B class of fit are required. The plug chamfer provides a moderate lead-in, making it well suited for through-hole work where the tap can exit the workpiece completely.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for general-purpose through-hole threading operations in ferrous and non-ferrous metals, plastics, and similar materials. It is used in machine shops, maintenance and repair environments, and production settings where 1\/2-13 UNC fastener threads are common. The 3.375-inch overall length and 0.367-inch shank diameter fit standard tap holders and CNC rigid-tapping chucks. It is appropriate for manual tapping with a tap wrench or power tapping with a drill press, tapping machine, or machining center running at appropriate feed and speed for the material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing chip packing in through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides moderate lead-in suitable for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers durability across general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 2B\/3B class of fit meet standard fastener thread tolerances\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish provides a baseline surface suitable for use with cutting fluid\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap holders, quick-change tapping chucks, and manual tap wrenches that accept a 0.367-inch shank diameter.

Ensure the workpiece is securely fixtured and that the correct pilot hole diameter for 1\/2-13 UNC has been drilled before tapping. Apply an appropriate cutting fluid for the material being threaded to extend tap life and improve thread quality. Do not reverse the tap under power without confirming the tapping machine or CNC control supports synchronized reversing.\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\/3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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: 1.656 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\u003eThread Pitch\u003c\/strong\u003e: 0.0769 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TT91085\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51749388812594,"sku":"TT91085","price":27.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d647337713659ef348df282bcb7e8920_1d9a3614-febf-46a6-ab89-af6b78dff144.jpg?v=1788905446","url":"https:\/\/voomisupply.com\/products\/titan-usa-tt91085-spiral-point-plug-tap-1-2-13-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
