Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance in general-purpose threading operations across ferrous and non-ferrous materials. The spiral point geometry pushes chips ahead of the cut, making it well suited for through-hole work where chip evacuation is critical. With an H3 thread limit and a 3B class of fit, it produces threads that meet standard tolerance requirements for most mechanical fastening assemblies. A reduced shank allows use in standard tap holders and extension holders, and the 6-inch overall length provides reach in deep or obstructed workpiece locations.\u003c\/p\u003e\n\u003cp\u003eThis extension tap is used in machining and fabrication environments where standard-length taps cannot reach the work. Typical applications include tapping recessed bores, deep fixtures, or workpieces mounted in setups that require additional clearance between the tool holder and the part surface. It is appropriate for right-hand threading in production and maintenance machining on manual mills, drill presses, and CNC equipment with rigid tapping capability. Machinists, tool and die makers, and maintenance technicians working in metal fabrication and industrial maintenance settings are the primary installers.\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\u003e1\/2-13 UNC thread size with H3 thread limit for consistent 3B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach in deep or obstructed setups\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles general-purpose threading in a range of materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows visual wear inspection during service\u003c\/li\u003e\n  \u003cli\u003eReduced shank design compatible with standard tap and extension holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use extension tap for any application requiring a 1\/2-13 UNC right-hand thread in through-hole configurations with standard 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension taps should be installed and operated by qualified machinists familiar with tapping speeds, cutting fluid requirements, and tap holder alignment for the specific workpiece material. Always secure the workpiece and ensure the tap is properly aligned to the drilled pilot hole before engagement to prevent tap breakage. Cutting fluid appropriate to the workpiece material should be applied throughout the tapping cycle. Follow all applicable shop safety procedures and equipment manufacturer guidelines when operating tapping equipment.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Shank\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.0844 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4704136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704206917938,"sku":"JY4704136","price":61.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5183dc1749207e40b6f3547410421137.jpg?v=1788421264","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4704136-extension-tap-1-2-13-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
