Built from high-speed steel with a bright uncoated finish, this plug chamfer tap drives chips forward ahead of the cutting edge, making it well suited for use in through-holes where chip ejection is critical. The H3 thread limit provides a controlled tolerance fit for 3B class thread production. With 3 flutes and right-hand thread direction, this tap is a standard choice for production and maintenance machining environments where consistent thread quality is required.\u003c\/p\u003e\u003cp\u003eThis tap is used in metalworking and machining operations where 5\/8-18 UNF threads are required in through-holes. Typical applications include fabrication shops, maintenance and repair operations, and production machining where controlled thread tolerance is necessary. The plug chamfer makes it appropriate for general-purpose tapping where the tap can pass fully through the workpiece. It is handled by machinists, tool and die makers, and maintenance mechanics working with ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point design pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer allows progressive thread engagement for general-purpose use\u003c\/li\u003e\n\u003cli\u003eH3 thread limit ensures consistent 3B class of fit tolerance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for standard tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 5\/8-18 UNF internal threads in through-hole applications requiring a 3B class of fit with H3 thread limit tolerance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a compatible tap holder or tapping chuck rated for the shank size. Secure the workpiece firmly before beginning the tapping operation and use an appropriate cutting fluid to extend tap life and improve thread finish. Always back the tap out periodically to break and clear chips even in through-hole applications. Follow standard machining safety practices including eye protection and proper spindle speed selection for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: K008578AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749002445106,"sku":"K008578AS","price":82.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b838acec80b61daeb5ac6e8f1ece97a2.jpg?v=1788900918","url":"https:\/\/voomisupply.com\/products\/hertel-k008578as-spiral-point-tap-5-8-18-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
