Manufactured from high speed steel with a bright uncoated finish, it is built for use in hand-tapping operations where controlled torque and clean thread form are required. The plug chamfer (3-5 thread lead) makes it suitable for starting and completing threads in most standard tapping setups. Overall length is 6-1\/16 inches with a 3-inch thread length. Four flutes provide adequate chip clearance for the thread size. This tap is a right-hand, H5 thread-limit tool intended for machinists, maintenance trades, and industrial fabrication professionals.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading operations in ferrous and non-ferrous materials where a UNS 1-3\/8-8 thread form is required. Typical applications include maintenance and repair of heavy equipment, industrial machinery, and structural fabrication. The plug chamfer style makes it versatile for both through-hole and open blind-hole work. It is commonly used in machine shops, field maintenance environments, and industrial facilities where non-standard UNS coarse-pitch threads are specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-3\/8-8 UNS thread form — non-standard coarse pitch for specialized industrial applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3-5 thread lead for versatile through-hole and shallow blind-hole tapping\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — suitable for use with cutting fluids and tapping compounds\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for controlled fit tolerance on internal threads\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute geometry provides chip clearance and thread form consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any application requiring a 1-3\/8-8 UNS internal thread.

Always secure the workpiece before tapping and use an appropriate cutting fluid or tapping compound for the workpiece material. Apply steady, consistent torque with a properly sized tap wrench — avoid side loading, which can cause tap breakage at this diameter. Inspect the tap for wear or chipping between uses, especially in harder materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-8\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 Style\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: 6-1\/16 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\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: 87024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730371903794,"sku":"87024","price":271.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e289d121e7659015e748756b2f28191.jpg?v=1788716242","url":"https:\/\/voomisupply.com\/products\/hertel-87024-hand-tap-1-3-8-8-uns-plug-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
