Built from submicron-grade solid carbide, it delivers the rigidity and edge retention needed for demanding cuts. The 2-flute geometry with a 45-degree right-hand helix provides aggressive chip evacuation and smooth cutting action. A ZrN (zirconium nitride) coating adds surface hardness and reduces friction, extending tool life in abrasive applications. The mill measures 5\/16 inches in diameter with a 2-1\/8 inch length of cut and a 4 inch overall length. Machinists and tool-and-die professionals install this in CNC machining centers and manual mills where tight tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling on a variety of workpiece materials. The centercutting design allows plunge entry, making it versatile for pocketing operations. The 5\/16 inch shank diameter fits standard ER collet chucks and end mill holders commonly found in both vertical and horizontal machining setups. The right-hand flute direction and upcut flute type work well in conventional milling strategies on CNC equipment. It belongs to GWS Series 2010, a line built around submicron carbide stock for applications where tool deflection and edge wear are primary concerns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for high rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and improves wear resistance in abrasive cuts\u003c\/li\u003e\n  \u003cli\u003e45-degree right-hand helix promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting capable  -  supports direct plunge entry for pocketing\u003c\/li\u003e\n  \u003cli\u003e2-flute design balances chip clearance and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 5\/16 inch diameter and 2-1\/8 inch length of cut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/16 inch ER collet chucks and end mill holders in CNC machining centers and manual milling machines.

Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully in the collet or holder and torque the retention nut to the tool holder specification  -  do not overtighten. Inspect the cutting edges under magnification before use; solid carbide is brittle and can chip if dropped or improperly stored.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/8 inches (2.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eFlute Type\u003c\/strong\u003e: Upcut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 313148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51963421688114,"sku":"313148","price":150.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e0ed050d357cd7747e6bc70e2b6be84_ad3f3ed5-1fcc-446c-bcb2-f20d49d2ddbe.jpg?v=1789948418","url":"https:\/\/voomisupply.com\/products\/gws-313148-square-end-mill-5-16-in-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
