Unlike cutting taps, thread forming taps displace material rather than remove it, producing stronger threads with no chips to clear. This tap features a bottoming chamfer for threading close to the bottom of blind holes. Built from high-speed steel with a bright uncoated finish, it is suited for use in ductile metals including aluminum, brass, and mild steel. Machinists and toolroom technicians install this tap in CNC machining centers, drill presses, and tapping machines requiring extended reach.\u003c\/p\u003e\u003cp\u003eThe 13148-010 is engineered for production and maintenance applications where deep or recessed hole locations demand additional clearance between the spindle and workpiece. The 4 inch overall length provides the extension needed in confined or deep-cavity setups. The bottoming chamfer allows threading to within a few threads of a blind hole floor. This tap fits the BALAX BXEXT series and is appropriate for both production runs and low-volume toolroom work on ductile ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material for chip-free, stronger threads\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer enables threading close to the base of blind holes\u003c\/li\u003e\n\u003cli\u003e4 inch overall length provides extended reach for recessed or deep-cavity applications\u003c\/li\u003e\n\u003cli\u003eH8 thread limit for consistent fit in 2B class of fit applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ductile metals\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction, standard right-hand thread orientation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production tap for use in 5\/16-18 UNC tapping applications requiring an extension-length tool.

Thread forming requires adequate cutting fluid or tapping compound formulated for the workpiece material. Ensure the tapping spindle is properly aligned to avoid tap breakage, particularly in blind hole applications. Always secure the workpiece firmly and confirm correct spindle speed before engaging the tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H8\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: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.375 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: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 13148-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51972295065906,"sku":"13148-010","price":109.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c754195fc94ec740261a520ec726be36_350ed530-c567-4a04-b6bc-158cdbc9e25e.jpg?v=1789965664","url":"https:\/\/voomisupply.com\/products\/balax-13148-010-extension-thread-forming-tap-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
