Built from high-speed steel with a bright, uncoated finish, it carries a 1\/4-20 UNC thread form at an H6 thread limit and a bottoming chamfer style. The extended 6-inch overall length gives machinists and toolroom technicians the reach needed to tap deep or recessed holes that standard-length taps cannot access. The 2B class of fit makes it suitable for most standard fastener applications requiring a functional thread engagement.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in production and maintenance machining environments where 1\/4-20 UNC internal threads are required in ductile or malleable materials such as aluminum, copper, brass, and low-carbon steel. The bottoming chamfer allows threading to the bottom of blind holes, making it well suited for close-tolerance fixtures, enclosures, and mechanical assemblies where full thread depth is critical. The extension design is commonly specified when a standard tap cannot clear the workpiece setup or fixturing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, producing stronger threads with no chips to clear\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach in deep or obstructed setups\u003c\/li\u003e\n  \u003cli\u003eH6 thread limit supports consistent 2B class of fit across production runs\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers durability in a wide range of shop conditions\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction for standard right-hand thread applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in materials suited to cold-forming operations, including aluminum, brass, copper, and low-carbon steel, where 1\/4-20 UNC internal threads at a 2B class of fit are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require proper lubrication matched to the workpiece material to prevent galling and premature tool wear. Ensure the tap is aligned perpendicular to the workpiece surface before engagement. Use a torque-controlled tapping head or tapping arm where possible to avoid overloading the tap shank. Power down and secure all machinery before changing or inspecting tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Thread Forming\u003c\/li\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\u003eThreads per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.191 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Shank\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: BXEXT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: BALAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12726-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51971161456946,"sku":"12726-010","price":114.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c754195fc94ec740261a520ec726be36.jpg?v=1789953811","url":"https:\/\/voomisupply.com\/products\/balax-12726-010-extension-tap-1-4-20-h6-thread-forming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
