Built from high speed steel (HSS), this end mill features a 5\/16-inch cutting diameter, a 9\/16-inch length of cut, and a 3\/8-inch straight-cylindrical shank with a Weldon flat. The 30-degree helix angle promotes smooth chip evacuation, and the centercutting geometry allows for plunge milling as well as conventional side milling. With a 2-1\/2-inch overall length and regular length classification, this tool fits standard end mill holders and collet chucks used in manual and CNC milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining cast iron, non-ferrous metals such as aluminum and brass, and steel. The uncoated HSS construction makes it a practical choice for general-purpose roughing and finishing passes where re-sharpening is preferred over coated carbide tools. It is commonly used in job shops, maintenance facilities, and production environments on knee mills, vertical machining centers, and similar equipment. The Series HG-2 designation indicates a standard general-purpose geometry optimized for a broad range of workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCentercutting design allows plunge cuts and slot milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute promotes efficient chip removal and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction supports re-sharpening to extend tool life\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank with Weldon flat provides positive tool retention in set-screw holders\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for general-purpose machining across cast iron, steel, and non-ferrous stock\u003c\/li\u003e\n  \u003cli\u003eSeries HG-2 regular-length geometry balances rigidity and reach for typical milling depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on cast iron, non-ferrous metals, and steel workpieces.

Secure the Weldon flat against the set screw in the tool holder to prevent axial pullout under cutting loads. Inspect the shank and holder bore for chips or damage before seating the tool. Follow the machine manufacturer's recommended RPM and feed rate guidelines for HSS tooling in the workpiece material being cut.\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 inch (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\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-2\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C41609\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51701460861234,"sku":"C41609","price":43.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86defdd418ca230117bd969cd4b6d415.jpg?v=1788400664","url":"https:\/\/voomisupply.com\/products\/cleveland-c41609-square-end-mill-5-16-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
