Built from high-speed steel with a bright, uncoated finish, this tap produces 1-1\/8-7 UNC right-hand threads and carries a 3B class of fit for standard tolerance applications. It runs 4 flutes and an H4 thread limit, making it a practical choice for machining shops and maintenance operations that need reliable, consistent thread quality without specialty coatings.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in general machining environments where UNC coarse-thread fastener holes are required in ferrous and non-ferrous materials. The bottoming chamfer — typically 1 to 2 threads — allows threading to the bottom of blind holes, which is a common requirement in fixture work, tooling plates, and machine component repair. At 5.75 inches overall length, it is compatible with standard tap handles and machine tap holders used in manual or light CNC tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip evacuation in through and shallow blind holes\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for 3B class of fit tolerancing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for use across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup that can affect thread tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style replacement or production tap for use wherever 1-1\/8-7 UNC bottoming taps are specified in manual tapping, drill press, or light machine tapping setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed in an appropriate tap handle or machine holder rated for the shank size before use. Always ensure the workpiece is securely fixtured and use cutting fluid appropriate to the workpiece material to prolong tool life and improve thread finish. Apply consistent, controlled torque when hand-tapping to avoid tap breakage — oversized or misaligned pilot holes are the most common cause of tap failure at this diameter. Dispose of worn taps per shop safety procedures; damaged high-speed steel tools should not be reground without proper equipment.\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\/8-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5-3\/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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 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: MSC-04489316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697671602482,"sku":"MSC-04489316","price":96.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e29c6d551c6b9dcd10ea739b8175b45.jpg?v=1788353981","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04489316-straight-flute-tap-1-1-8-7","provider":"Voomi Supply","version":"1.0","type":"link"}
