It is ground to a 3\/8-24 UNF thread form with an H3 thread limit, which controls tolerance for a precise 3B class of fit. The tap is manufactured from high-speed steel and features a bright, uncoated finish for general-purpose use. With three flutes and a spiral point geometry, it pushes chips forward through the hole rather than backing them out, keeping the cutting zone clear. Overall length is 6 inches, giving extended reach in deep-set or obstructed workpieces. Machinists and maintenance technicians use this tap in production and repair environments where standard-length taps cannot access the thread location.\u003c\/p\u003e\n\u003cp\u003eThis extension tap is suited for threading through holes in steel, aluminum, brass, and similar machinable materials. The plug chamfer — typically 3 to 5 threads of lead — makes it appropriate for starting in a pre-drilled hole and cutting to near full depth. It is commonly used in machine shops, maintenance facilities, and fabrication environments where 3\/8-24 UNF fastener threads must be cut with extended reach. The 3B class of fit is the standard tolerance class for most general-purpose UNF threaded assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging in through-hole threading\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit provides controlled tolerance for a 3B class of fit\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a broad range of machinable metals\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3 to 5 thread lead for standard through-hole starts\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach in deep or obstructed bores\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suited for general-purpose and lower-volume threading operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use tap for cutting 3\/8-24 UNF right-hand internal threads in through-hole workpieces requiring extended tool reach and a 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eUse in a tapping head, drill press, or CNC machine with appropriate tapping fluid for the workpiece material. Ensure the pilot hole is drilled to the correct tap drill size for 3\/8-24 UNF before threading. Power down and secure the workpiece before tool changes. Do not apply excessive axial force — allow the spiral point geometry to advance the tap naturally to avoid flute breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\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: 0.5 pounds\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: JY9975673\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722243932466,"sku":"JY9975673","price":64.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36801e9a8b1809635ff81e20a70c2cf4.jpg?v=1788588069","url":"https:\/\/voomisupply.com\/products\/value-collection-jy9975673-extension-tap-3-8-24-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
