With a 5\/8-inch diameter and 7-flute geometry, this tool delivers aggressive metal removal rates while maintaining surface finish quality. The 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces. An AlTiCrN coating provides high-temperature oxidation resistance and extended tool life in abrasive and hard materials. This end mill is a single-end tool with a right-hand cut and right-hand flute direction. It is installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous metals, hardened steels, and high-temperature alloys where heat generation and tool wear are primary concerns. The 1-5\/8-inch length of cut accommodates moderate-depth slotting and peripheral milling operations. The 5\/8-inch shank diameter fits standard ER collet chucks, shrink-fit holders, and hydraulic toolholders used on vertical and horizontal machining centers. The Series HS designation indicates it is engineered for high-speed machining strategies with consistent dimensional repeatability across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute design increases feed rate capability and improves finish in semi-finishing and finishing passes\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating resists heat and wear in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes smooth chip flow and reduced radial cutting forces\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flutes for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end construction with non-centercutting geometry — not suited for direct plunge operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 5\/8-inch shank toolholders including ER collet, shrink-fit, and hydraulic chuck systems used on CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine power isolated before tool changes. Ensure the shank is clean and fully seated to the recommended gauge-line depth in the toolholder before tightening. This tool is not centercutting and must not be used for direct plunge entry into solid material. Verify runout with a dial indicator after installation to confirm proper seating and minimize premature edge wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches \/ 15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.625 inches \/ 41.23 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.5 inches \/ 88.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 312679\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738719093042,"sku":"312679","price":184.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58451c07ae9d568ca346a0ce676a0525.jpg?v=1788803368","url":"https:\/\/voomisupply.com\/products\/accupro-312679-square-end-mill-5-8-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
