Built from high-speed steel with a bright\/uncoated finish, this tap delivers reliable thread cutting in a range of workpiece materials. The taper chamfer eases entry and distributes cutting load across the leading threads, making it well suited for through-hole applications. With 4 flutes and an H3 thread limit, it holds tight dimensional tolerances consistent with a 3B class of fit. Machinists and toolroom professionals rely on this style of tap for production and maintenance threading operations where left-hand thread orientation is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, toolroom, and maintenance environments where left-hand 5\/8-11 UNC threads must be cut. Left-hand taps are specified when the application demands reverse-thread fastening to prevent loosening under rotational loads, such as in rotating shaft assemblies, specialized fixtures, and certain mechanical linkages. The taper chamfer style makes it appropriate for through-holes where full thread engagement is needed along the usable thread length of 1-13\/16 inches. It is typically run in a drill press, tapping head, CNC machining center, or by hand with a tap wrench.\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 for reverse-thread applications\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes cutting forces across multiple leading threads for smooth entry\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides good chip clearance and tap rigidity\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures dimensional accuracy for 3B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers toughness across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluid in standard threading operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production tap for any application requiring a left-hand 5\/8-11 UNC straight flute taper tap with a 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by qualified machinists or toolroom technicians using appropriate tapping equipment. Always secure the workpiece firmly and ensure the tap is aligned perpendicular to the drilled hole before engagement. Use a suitable cutting fluid for the workpiece material to extend tap life and improve thread quality. Because this is a left-hand tap, rotation direction must be reversed relative to standard right-hand tapping procedures.\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 UNC\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\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\u003eChamfer Type\u003c\/strong\u003e: Taper\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 (OAL)\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\u003eOversize\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: MSC-04916136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722183344434,"sku":"MSC-04916136","price":54.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5ee7c1314fe896556568896e926a1a5.jpg?v=1788586954","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04916136-straight-flute-tap-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
