It carries a 3\/4-inch cutting diameter, a 1-inch length of cut, and a 37-degree right-hand helix. The three-flute geometry balances chip evacuation and surface finish across a broad range of metalcutting applications. The ZrN coating adds heat resistance and lubricity, extending tool life in ferrous and non-ferrous materials. This tool is centercut and configured for extended-reach setups where standard-length tools cannot reach the workpiece.\u003c\/p\u003e\n\u003cp\u003eThe 315664 is suited for milling operations in machine shops, production environments, and toolroom applications. Its solid carbide construction and submicron grain structure make it appropriate for side milling, slotting, and peripheral milling in steel, aluminum, and similar materials. The extended-reach 6-inch overall length allows access to deep pockets, tall workpiece features, and setups where clearance is limited. It is installed by machinists and CNC operators running vertical or horizontal machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch cutting diameter with 1-inch length of cut for solid material removal in a single pass\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN coating improves lubricity and heat resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003e37-degree right-hand helix promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eThree-flute design balances chip clearance and finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercut geometry allows plunge entry; 6-inch OAL provides extended reach capability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 2032 solid carbide square end mill compatible with standard 3\/4-inch collets, end mill holders, and milling chucks used in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before loading or unloading the tool. Seat the 3\/4-inch shank fully into a clean, properly sized collet or end mill holder and torque the retention mechanism to the toolholder manufacturer specification. Inspect the cutting edges and coating for chips or damage before each use, and verify runout with a dial indicator after setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2032\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.76 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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 315664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":52051953549618,"sku":"315664","price":469.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e3e5f660cf19e8f2b626180c6fb8eea_31c17e88-2191-4cb9-a766-65549c7173a5.jpg?v=1790035215","url":"https:\/\/voomisupply.com\/products\/gws-315664-square-end-mill-3-4-in-3-flute-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
