With a 5\/8-inch (0.625-inch decimal) mill diameter and a 2-1\/2-inch length of cut, it delivers reliable material removal in cast iron, non-ferrous metals, and steel. The 5\/8-inch straight cylindrical shank with Weldon flat provides secure toolholder engagement. A 30-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. This end mill is centercutting, allowing plunge and interpolation operations without a pre-drilled hole. It belongs to the CLEVELAND HG-4C series and ships uncoated and ready to run.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for manual mills and CNC machining centers in job shop, maintenance, and production environments. Its regular-length geometry fits standard toolholders and makes it appropriate for general-purpose profiling, slotting, and pocket milling in cast iron, steel, and non-ferrous materials. Right-hand cut and right-hand flute orientation match the majority of standard spindle configurations. Machinists and tool-and-die professionals working in ferrous and non-ferrous stock will find the HG-4C series geometry effective across a range of common milling tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 flutes with 30-degree right-hand spiral for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge milling and ramp entry\u003c\/li\u003e\n\u003cli\u003e5\/8-inch shank with Weldon flat for positive anti-pullout grip in toolholders\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction suitable for cast iron, steel, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eUncoated finish — ready for use or post-grind coating if required\u003c\/li\u003e\n\u003cli\u003eHG-4C series regular length — compatible with standard milling machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock end mill for general milling applications in cast iron, non-ferrous metals, and steel using machines equipped with 5\/8-inch straight shank or Weldon flat toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and tighten in an appropriate end mill holder or collet chuck before powering the spindle. Ensure the Weldon flat is properly aligned with the set screw in the holder for secure clamping. Follow machine tool manufacturer torque and runout specifications for the toolholder. Inspect the cutting edges for wear or chipping before each use and replace when edge condition degrades to avoid workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches decimal)\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCoating\u003c\/strong\u003e: Uncoated\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-4C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C41338\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695091974450,"sku":"C41338","price":131.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22e7e0cab9991a9b58507ef0d8ed0060.jpg?v=1788331234","url":"https:\/\/voomisupply.com\/products\/cleveland-c41338-square-end-mill-5-8-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
