Built from high speed steel, it delivers consistent cutting performance across cast iron, non-ferrous metals, and steel. The tool measures 3\/8 inch in diameter with a 2-1\/2 inch length of cut and a 4-1\/4 inch overall length, placing it in the extra-long category. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The centercutting geometry allows both plunge and peripheral milling operations. This end mill is uncoated and fits straight-cylindrical or Weldon flat toolholders.\u003c\/p\u003e\n\u003cp\u003eThe C41386 is suited for general-purpose milling on manual mills, CNC machining centers, and knee mills found in job shops, production facilities, and maintenance shops. Its extra-long length of cut makes it well suited for deep-pocket machining, slotting, and side milling where standard-length end mills cannot reach. The 3\/8 inch shank allows use in collet chucks, end mill holders, and side-lock holders with matching bore sizes. Applications include ferrous and non-ferrous workpieces where uncoated HSS tooling is the appropriate choice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch cutting diameter with matching 3\/8 inch straight shank, compatible with Weldon flat toolholders\u003c\/li\u003e\n  \u003cli\u003e4 flutes with spiral geometry and 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch length of cut rated for deep-pocket and slotting operations\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction suitable for cast iron, non-ferrous metal, and steel workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in straight-cylindrical and Weldon flat toolholders with a 3\/8 inch bore.

Ensure the machine spindle is fully stopped and locked out before inserting or removing end mills from the toolholder. Verify holder bore size and setscrew engagement to the Weldon flat before starting the cut. Do not exceed the recommended depth of cut for the workpiece material and machine rigidity.\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 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/4 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\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\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eSeries\u003c\/strong\u003e: HG-4C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: C41386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700112556338,"sku":"C41386","price":78.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d415cd54b387e49d035ab38b1b8ae07.jpg?v=1788386163","url":"https:\/\/voomisupply.com\/products\/cleveland-c41386-square-end-mill-3-8-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
