Manufactured from high speed steel with a titanium nitride (TiN) finish, it offers improved surface hardness and wear resistance compared to uncoated HSS tooling. The 0.25-inch cutting diameter pairs with a 0.375-inch straight-cylindrical shank featuring a Weldon flat, providing positive clamping in standard end mill holders. With a 30-degree helix angle and center-cutting geometry, this tool is suited for slotting, peripheral milling, and plunge operations. It belongs to Cleveland's HG-2 series and is intended for use by machinists and tool-and-die professionals in conventional milling setups.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling cast iron, non-ferrous metals, and steel in both manual and CNC machining centers. The regular-length configuration — 0.5 inch length of cut and 2.4375 inches overall length — makes it a practical choice for general-purpose work where extended reach is not required. The right-hand cut, right-hand spiral flute design produces efficient chip evacuation during climb or conventional milling passes. It is appropriate for use in job shops, maintenance machining, and prototype work where HSS tooling is preferred over carbide for interrupted cuts or tougher setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25-inch cutting diameter with 0.5-inch length of cut for controlled depth engagement\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with TiN coating for extended tool life and reduced friction\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle spiral flute promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003e0.375-inch straight-cylindrical shank with Weldon flat for secure holder retention\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard milling spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with cast iron, non-ferrous metals, and steel workpiece materials as specified by the manufacturer.

Secure the shank in a properly sized end mill holder or collet, using the Weldon flat to seat the set screw for positive drive. Verify runout with an indicator before beginning cuts; excessive runout accelerates tool wear and degrades surface finish. Follow applicable shop safety practices and machine tool manufacturer guidelines for speeds, feeds, and clamping torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: TiN (Titanium Nitride)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: C41552\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716616913202,"sku":"C41552","price":48.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88241de29170949afaee8fc634092d2b.jpg?v=1788528958","url":"https:\/\/voomisupply.com\/products\/cleveland-c41552-square-end-mill-0-25-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
