The plug chamfer — typically 3 to 5 threads — allows the tap to start easily in through-holes and blind holes with adequate clearance. Four straight flutes provide chip clearance and cutting stability at this large thread diameter. Overall length is 6-3\/8 inches with a 3-inch thread length, giving machinists and maintenance technicians sufficient reach for standard-depth UNS threaded holes.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for machine shops, maintenance and repair operations, and industrial fabrication environments where 1-1\/2-8 UNS threads are required. The UNS thread form is common in specialized fastener, pipe flange, and heavy equipment applications where unified standard pitches do not apply. The H5 thread limit designates a ground tolerance class appropriate for general-purpose tapping where a moderate class-of-fit is needed. Installation is performed by hand with a tap wrench or by a low-speed machine tap holder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-8 UNS right-hand thread form with H5 ground thread limit for consistent tolerance control\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (approximately 3-5 leading threads) eases entry in both through and blind-hole applications\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute geometry provides chip clearance and cutting stability at large diameters\u003c\/li\u003e\n  \u003cli\u003eBright uncoated high speed steel finish suitable for use with cutting fluids on a wide range of materials\u003c\/li\u003e\n  \u003cli\u003e6-3\/8 inch overall length with 3-inch thread length accommodates standard-depth UNS threaded holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct application tap for any operation requiring a 1-1\/2-8 UNS right-hand plug tap with H5 thread limit in high speed steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by a machinist or maintenance technician using a properly sized tap wrench or a low-speed machine spindle with a floating tap holder. Always apply cutting fluid appropriate for the workpiece material before and during tapping to extend tool life and improve thread quality. Secure the workpiece fully before starting the tap to maintain alignment and prevent tap breakage. Worn or damaged taps should be replaced rather than reused to avoid thread damage in the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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: 6-3\/8 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 87026\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731896828210,"sku":"87026","price":296.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db3895372cdf0f53e9b62459a0884247.jpg?v=1788736237","url":"https:\/\/voomisupply.com\/products\/hertel-87026-hand-tap-1-1-2-8-uns-plug-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
