Built from high speed steel with a bright, uncoated finish, this tap delivers consistent thread form across production and maintenance environments. The spiral point geometry pushes chips forward ahead of the cutting edge, reducing clogging and allowing reliable performance in through-hole work. At 4 inches overall length, the extended reach makes it well suited for threading recessed or hard-to-access bores where standard-length taps cannot engage. The H3 thread limit and 2B class of fit ensure dimensional accuracy within standard tolerance requirements for 8-32 fastener assemblies.\u003c\/p\u003e\u003cp\u003eThis extension tap is used in metalworking applications where 8-32 UNC threaded holes are required in steel, aluminum, or similar machinable materials. The plug chamfer, with its gradual lead-in, is the standard choice for through-hole tapping in production machining, maintenance and repair operations, and general fabrication. The 2-flute configuration provides adequate chip clearance for soft to medium-hardness metals. Machinists, tool and die workers, and maintenance technicians working on assemblies requiring 8-32 fastener points will find this tap appropriate for both CNC and hand-tapping operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides gradual lead-in for standard through-hole applications\u003c\/li\u003e\n\u003cli\u003eH3 thread limit with 2B class of fit for accurate 8-32 UNC thread production\u003c\/li\u003e\n\u003cli\u003e4 inch overall length for extended reach into recessed or deep features\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles a wide range of machinable metals\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 8-32 UNC internal threads in through-hole configurations across general metalworking and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and operated by machinists or maintenance technicians using a tap wrench, tapping head, or CNC tapping cycle. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Ensure the tap is properly aligned with the bore centerline before applying torque to prevent tap breakage. Secure the workpiece firmly before tapping operations begin.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Spiral Point Extension Tap\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: 2B\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eReduced Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: G837631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730346180914,"sku":"G837631","price":72.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86ec2ccaec8552c4b32bcf562ae4d63b.jpg?v=1788715746","url":"https:\/\/voomisupply.com\/products\/hertel-g837631-extension-tap-8-32-2-flute-h3-spiral-point","provider":"Voomi Supply","version":"1.0","type":"link"}
