Built from powdered metal and coated with a titanium carbonitride (TiCN) finish, it delivers improved wear resistance and tool life compared to standard high-speed steel tooling. The three-flute, spiral configuration runs with a right-hand cut and right-hand flute orientation, with a 42-degree helix angle for efficient chip evacuation. At 0.75 inches in diameter with a 3-inch length of cut and a 5.25-inch overall length, this is a regular-length end mill suited to general-purpose and non-ferrous metal milling operations. It is center-cutting, allowing direct plunge entry into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThe C40351 is designed for milling non-ferrous metals as its primary workpiece material, making it appropriate for aluminum, brass, copper, and similar alloys. The straight-cylindrical shank with a Weldon flat seats securely in standard end mill holders and collet chucks. It is used in CNC machining centers and manual mills across job shops, toolrooms, and production environments where consistent cutting performance in non-ferrous materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal construction for enhanced toughness and edge retention over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e42-degree helix angle promotes effective chip evacuation in non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute with spiral flute design for smooth, consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on straight shank provides positive drive and prevents slippage in the holder\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank replacement end mill for applications requiring a 0.75-inch diameter, three-flute, regular-length tool in any end mill holder or collet system that accepts a 0.75-inch straight-cylindrical shank with a Weldon flat.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat against the set screw in the holder and torque according to the toolholder manufacturer's specification. Confirm runout with a dial indicator before beginning the cut, and verify that cutting parameters are appropriate for the specific 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\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches (3.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003eHelix Angle\u003c\/strong\u003e: 42 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\u003eCenter-Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\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: PM-539R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: C40351\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700012581170,"sku":"C40351","price":258.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa0f15de0e5c6a115cc5d5118580a19c.jpg?v=1788384951","url":"https:\/\/voomisupply.com\/products\/cleveland-c40351-square-end-mill-3-4-in-3-flute-ticn-pm-539r","provider":"Voomi Supply","version":"1.0","type":"link"}
