Built from micrograin solid carbide, it delivers the hardness and wear resistance required for demanding cutting conditions. The tool features a 5\/8-inch cutting diameter, a 1-1\/4-inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and reduced cutting forces. A ZrN (zirconium nitride) coating provides enhanced surface hardness and lubricity, extending tool life in ferrous and non-ferrous materials. Installed by machinists and CNC operators, this end mill suits both manual mills and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling operations in production and job shop environments. The centercutting geometry allows plunge entry, adding versatility for pocketing operations. Right-hand cut and right-hand spiral flute configuration is standard for conventional milling setups. The 5\/8-inch shank diameter fits directly into standard ER collets, side-lock holders, and shrink-fit tooling. The 3-1\/2-inch overall length provides adequate clearance for most workholding setups without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eZrN coating improves wear resistance and reduces built-up edge in non-ferrous and ferrous cuts\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes smooth chip flow and reduces cutting pressure\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry for pocketing operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry for consistent chip evacuation throughout the length of cut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting a 5\/8-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with toolholder torque procedures and runout verification. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Verify tool projection and runout with a dial indicator before commencing cuts to prevent premature tool failure. Follow the machine manufacturer and toolholder manufacturer guidelines for proper collet or chuck seating depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches (3-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 313370\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747640639794,"sku":"313370","price":193.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16cc8356e40a3be7a73f89f847b8c9c1.jpg?v=1788883919","url":"https:\/\/voomisupply.com\/products\/accupro-313370-square-end-mill-5-8-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
