Built from high-speed steel with a bright, uncoated finish, this tap is suited for threading operations where a standard spiral-flute tap is not required and chip evacuation can be managed by the operator. With 4 flutes and an H3 thread limit, it holds tight dimensional tolerances for a 3B class of fit. The 1-13\/16-inch thread length and 3-13\/16-inch overall length make it appropriate for through-holes and shallow blind holes where full thread depth near the bottom of the hole is the goal. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in manual tapping operations or rigid tapping setups on machine tools where left-hand thread production is required. The bottoming chamfer — typically 1 to 2 thread leads — allows threads to be cut to within a few threads of the bottom of a blind hole. It is well suited for ferrous and non-ferrous materials in general machining environments. The bright, uncoated finish makes it a cost-effective choice for lower-volume production runs or toolroom use where coated tooling is not warranted.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread form with left-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for rigidity and stability during tapping\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for 3B class-of-fit tolerance control\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 — no additional coating to affect thread tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom tap for any machining application requiring a 5\/8-11 UNC left-hand bottoming tap with a 3B class of fit and H3 thread limit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and used by machinists and toolroom professionals following standard tapping procedures. Before tapping, ensure the workpiece is securely fixtured and the correct drill size for a 5\/8-11 UNC thread has been used to prepare the hole. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Left-hand taps require counterclockwise rotation to advance — confirm machine or tap wrench direction before starting to avoid tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-13\/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: 0.45 pounds\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: MSC-04916128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716113039666,"sku":"MSC-04916128","price":56.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e76da6b3432fb4df7d3089be73190106.jpg?v=1788521930","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04916128-straight-flute-tap-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
