With a 5\/16 inch cutting diameter and a 1 inch length of cut, this tool delivers efficient material removal and fine surface finishes in a single-end configuration. The AlTiN coating provides thermal resistance and extended tool life in dry or high-speed cutting conditions. A 41-degree variable helix angle reduces chatter and harmonics during the cut, improving both finish quality and tool stability. This end mill is installed and operated by CNC machinists and toolroom professionals working in job shops, production facilities, and precision machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling applications in ferrous and hardened materials where tool life and cutting stability are priorities. The right-hand cut and right-hand flute configuration is standard for conventional CNC vertical and horizontal machining centers. With a 5\/16 inch shank diameter matching the cutting diameter, it seats directly into standard ER collets or end mill holders of the appropriate size. The non-centercutting geometry means this tool is intended for peripheral and side milling rather than plunge operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute geometry increases feed rates and improves surface finish compared to lower-flute-count tools\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high-temperature hardness and oxidation resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e41-degree variable helix reduces vibration and chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for use in standard CNC machining setups\u003c\/li\u003e\n\u003cli\u003eNon-centercutting design optimized for side milling and peripheral passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNC machining centers with ER collet systems or end mill holders accepting a 5\/16 inch shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut to the tool holder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear on a 7-flute tool at this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes, 41 degrees\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57920-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728425550130,"sku":"57920-C6","price":120.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0b206c08658414209a6c13a8955e33d_fa750b2f-a2f9-4449-80e1-9a43b4af4bf7.jpg?v=1788691011","url":"https:\/\/voomisupply.com\/products\/harvey-tool-57920-c6-square-end-mill-5-16-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
