With a 5\/16 inch cutting diameter and a 1\/2 inch length of cut, this tool removes material efficiently in profiling, slotting, and peripheral milling applications. The four-flute spiral geometry with a 30-degree helix angle promotes smooth chip evacuation and improves surface finish. A titanium nitride (TiN) coating increases surface hardness and reduces friction at the cutting edge, extending tool life in production environments. Centercutting capability allows plunge entry without a pre-drilled pilot hole, adding versatility to the tool path.\u003c\/p\u003e\u003cp\u003eThis end mill suits CNC machining centers, knee mills, and manual milling machines used in job shops, toolrooms, and maintenance machining operations. It is appropriate for milling aluminum, brass, mild steel, and similar machinable alloys. The right-hand cut and right-hand flute configuration is the standard orientation for conventional milling spindles. The 2 inch overall length and 5\/16 inch shank diameter are sized for standard ER collets and end mill holders commonly found in light-duty machining setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance versus high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eTiN finish reduces cutting friction and extends edge life in production runs\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eFour-flute configuration balances chip clearance with surface finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for use on standard CNC and manual milling spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock solid carbide square end mill for use in ER collet chucks, end mill holders, and similar toolholding systems accepting a 5\/16 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Confirm spindle is fully stopped and machine is in an energy-isolated state before changing tooling. Seat the shank to the full recommended insertion depth in the collet or holder and torque the retention nut per the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches (1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eWeight\u003c\/strong\u003e: 0.08 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754514776370,"sku":"750416","price":42.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d0673630a9d2897b5e0f79e1d3a68f7.jpg?v=1788946217","url":"https:\/\/voomisupply.com\/products\/hertel-750416-square-end-mill-5-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
