It runs a 5\/8-inch cutting diameter with a 1-5\/8-inch length of cut and five spiral flutes for aggressive material removal with strong chip evacuation. The 38-degree helix angle reduces cutting forces and improves surface finish. An AlTiCrN coating delivers excellent heat resistance and wear protection at elevated cutting temperatures. The variable index design reduces chatter and vibration during cuts. This end mill is a single-end tool intended for use by machinists and tool-and-die professionals on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThe 311725 is suited for finish and semi-finish milling operations in steel, stainless, cast iron, and hardened workpiece materials. The micrograin carbide substrate supports edge sharpness retention over extended run times. Its right-hand cut and right-hand flute direction are standard for conventional and climb milling setups. The 5\/8-inch shank diameter matches common ER and side-lock toolholders. At 3.5 inches overall length, it fits standard tool-length reach requirements without extended-reach toolholding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge retention in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiCrN coating resists heat and oxidation during high-speed dry or minimal-lubrication cutting\u003c\/li\u003e\n  \u003cli\u003eFive-flute configuration increases feed rate capability over four-flute designs\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle reduces cutting force and improves surface finish quality\u003c\/li\u003e\n  \u003cli\u003eVariable index spacing dampens chatter in difficult setups\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fitment end mill for CNC machining centers and manual mills using standard 5\/8-inch bore toolholders, including ER collet chucks and side-lock holders.

Ensure the shank is clean and free of chips before seating in the collet or holder. Torque the toolholder to the machine manufacturer's specification. Confirm runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 inches \/ 41.23 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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  \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: 311725\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731152929074,"sku":"311725","price":214.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/786c8cb2129c1785b71d12a0ec86aaa2.jpg?v=1788727634","url":"https:\/\/voomisupply.com\/products\/accupro-311725-square-end-mill-5-8-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
