Built from high speed steel (HSS) with a titanium carbonitride (TiCN) finish, it delivers improved surface hardness and lubricity compared to uncoated HSS tooling. The 3\/8 inch cutting diameter pairs with a 3\/4 inch length of cut and a 2-1\/2 inch overall length, making it well suited for standard-depth slotting, profiling, and peripheral milling. The 30-degree spiral flute geometry promotes smooth chip evacuation and reduces cutting forces. Licensed machinists, tool and die makers, and CNC operators are the primary users of this end mill in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThe C33256 is rated for use in cast iron, non-ferrous metals, and steel. Its centercutting design allows plunge entry directly into a workpiece without pre-drilling. The straight cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw-style collet chucks, which are common in both manual milling machines and CNC machining centers. The regular-length body keeps overhang short, supporting rigidity in tight-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and extends tool life compared to bare HSS\u003c\/li\u003e\n\u003cli\u003e4 flutes with 30-degree right-hand spiral helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eStraight shank with Weldon flat for secure clamping in set-screw holders\u003c\/li\u003e\n\u003cli\u003eRated for cast iron, steel, and non-ferrous metal workpiece materials\u003c\/li\u003e\n\u003cli\u003eSeries HG-4C regular-length configuration minimizes deflection at standard depths of cut\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard addition for 3\/8 inch end mill holders and ER collet chucks used in manual knee mills and CNC machining centers.

Always power down and lock out the spindle before changing tooling. Seat the shank fully into the holder and torque the set screw against the Weldon flat per the tool holder manufacturer's specification. Inspect the cutting edges for chips or wear before each use and replace the end mill when surface finish or dimensional accuracy degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\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\u003eFinish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical with Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C33256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51701915615538,"sku":"C33256","price":58.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b37c16cfe6bce743d06959f7ed1671b5.jpg?v=1788406835","url":"https:\/\/voomisupply.com\/products\/cleveland-c33256-square-end-mill-3-8-inch-4-flute-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
