With 6 flutes and a bottoming chamfer, this tap is suited for threading holes that require threads cut close to the bottom of a blind bore. Constructed from high-speed steel (HSS) with a bright\/uncoated finish, the JY4874061 offers reliable cutting performance in general machining applications. The H5 thread limit provides the controlled oversize tolerance required for plated or close-tolerance threaded assemblies. Installation is performed by machinists and toolroom technicians using standard tapping equipment.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, maintenance, and production environments where 1-1\/2-8 UNS bottoming threads are required. The straight flute design makes it appropriate for threading short-chipping or brittle materials. With a thread length of 3 inches and an overall length of 6-3\/8 inches, the tap fits standard tapping heads and CNC machine spindles configured for large-diameter threading operations. Right-hand thread direction is standard for conventional fastener and fitting assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e6-flute design provides even cutting load distribution on large-diameter threads\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction supports use across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit maintains controlled oversize tolerance for close-fit threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish for general-purpose tapping without coating compatibility concerns\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — compatible with flood or manual lubrication setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose straight flute tap for 1-1\/2-8 UNS right-hand threaded applications in standard tapping heads, drill press setups, and CNC machining centers capable of accommodating the 6-3\/8-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and operated by machinists using appropriate tapping heads, tapping attachments, or CNC rigid-tap cycles. Always ensure the workpiece is securely fixtured and the spindle speed is set to a value appropriate for the workpiece material and tap diameter before beginning the threading operation. Apply cutting fluid or tapping oil to reduce heat and extend tool life. Do not force a bottoming tap into a hole without first clearing chips, as chip packing in blind bores can cause tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4874061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690291036466,"sku":"JY4874061","price":257.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e34e15cb3891c33bbc69d9446b88b84.jpg?v=1788268225","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4874061-straight-flute-tap-1-1-2-8-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
