Made from high-speed steel with a bright, uncoated finish, this tap uses a forming action rather than cutting flutes to displace material and create clean, strong threads without producing chips. The bottoming chamfer allows threading close to the bottom of blind holes. With an overall length of 4 inches, it provides the reach needed for recessed or deep-set workpieces. The H3 thread limit ensures consistent fit tolerance for 3B class of fit assemblies.\u003c\/p\u003e\u003cp\u003eThis extension tap is suited for use in machining, fabrication, and maintenance applications where an 8-32 threaded hole must be formed in a location inaccessible to standard-length taps. It is commonly used in precision metalworking on ductile materials such as aluminum, mild steel, and similar alloys. The thread forming design produces no chips, making it a practical choice for blind holes where chip evacuation is a concern. Machinists, tool and die makers, and maintenance technicians are the typical installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting, eliminating chips in blind-hole applications\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer allows threading to the bottom of shallow or blind holes\u003c\/li\u003e\n\u003cli\u003e4-inch overall length provides extended reach for recessed workpieces\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction offers durability across a range of ductile metals\u003c\/li\u003e\n\u003cli\u003eH3 thread limit with 3B class of fit for consistent, controlled thread tolerance\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction with reduced-shank-free design for standard chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming extension tap for 8-32 UNC applications requiring a bottoming chamfer and extended reach in the BXEXT series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician familiar with tapping operations on metallic workpieces. Ensure the workpiece is securely fixtured and the pilot hole is sized correctly for thread forming prior to tapping. Use appropriate tapping fluid for the base material to extend tool life and improve thread quality. Do not exceed the recommended speed for the material being tapped, and back the tap out periodically if resistance increases unexpectedly.\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: 8-32\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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\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: 11703-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52059191836978,"sku":"11703-010","price":107.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da7b9deac3864fd8cc41a6c8ae51c18f.jpg?v=1790040194","url":"https:\/\/voomisupply.com\/products\/balax-11703-010-thread-forming-extension-tap-8-32-h3","provider":"Voomi Supply","version":"1.0","type":"link"}
