It features a 3\/8 inch diameter cutting edge, seven flutes, and an AlTiCrN (aluminum titanium chromium nitride) coating that improves heat resistance and extends tool life at elevated cutting speeds. The 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With a 1\/2 inch length of cut and 2 inch overall length, this end mill is well suited for shallow-to-moderate depth passes in demanding machining environments. It is installed by machinists and tool-and-die professionals in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits applications requiring tight tolerances and smooth surface finishes in hardened steels, stainless steels, cast iron, and similar difficult-to-machine materials. The seven-flute geometry increases the number of cutting edges in contact with the workpiece, allowing for higher feed rates at reduced chip loads per tooth. It is appropriate for finishing and semi-finishing operations in production machining, toolroom work, and die and mold applications where tool rigidity and coating durability are priorities. The 3\/8 inch shank diameter matches standard collet and end mill holder sizes common to most machining setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiCrN coating provides high-temperature hardness and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eSeven flutes allow higher feed rates compared to four- or five-flute designs\u003c\/li\u003e\n  \u003cli\u003e38-degree right-hand spiral helix promotes efficient chip flow and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard CNC and manual milling spindle configurations\u003c\/li\u003e\n  \u003cli\u003eSingle-end design — 3\/8 inch shank diameter matches cutting diameter for direct collet clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill compatible with standard 3\/8 inch collets, end mill holders, and shrink-fit tooling systems used in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Secure the shank fully within the collet or holder to the recommended engagement depth before torquing the retention hardware. Confirm spindle runout is within acceptable limits before cutting, as excessive runout accelerates carbide tool wear. Always follow shop safety protocols, including proper guarding and chip containment, when operating end mills at high RPM.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches \/ 9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches (0.5 inches \/ 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\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)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiCrN\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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: 0.03 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 312575\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730410570034,"sku":"312575","price":70.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a31418f96d88f50ea71b0508fafa937.jpg?v=1788716979","url":"https:\/\/voomisupply.com\/products\/accupro-312575-square-end-mill-3-8-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
