Manufactured from high-speed steel with a bright\/uncoated finish, this tap delivers reliable performance across a range of ferrous and non-ferrous materials. The 4-flute configuration provides stable cutting action and adequate chip clearance for the thread size. With an overall length of 3-13\/16 inches and an H3 thread limit, this tap holds close tolerance for production and maintenance threading operations. Machinists, tool-and-die tradespeople, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bottoming tap is suited for applications where thread engagement must extend to the bottom of a blind hole, or where a preceding taper or plug tap has already started the thread. The 5\/8-20 UNS thread form is used in specialized mechanical assemblies, fluid fittings, and custom-engineered components requiring a finer pitch than the standard UNC series. It is appropriate for bench work, drill press setups, and CNC tapping operations in shops handling both production runs and one-off repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the full depth of blind holes\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes provide stable cutting geometry and chip relief\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent 3B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids in general-purpose threading\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 5\/8-20 UNS 3B class of fit internal threads.

Secure the workpiece firmly before tapping to prevent movement under load. Apply an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Because this is a bottoming tap, use a taper or plug tap first to start and advance the thread before finishing with this tool to avoid tap breakage in blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eOverall Length\u003c\/strong\u003e: 3-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: JY4846150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691812978994,"sku":"JY4846150","price":79.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3e5151b8dc5bcfcda99a7873d0818eb.jpg?v=1788290039","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4846150-straight-flute-tap-5-8-20-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
