Built from powdered metal (PM) and coated with a PVD-applied TiCN finish, it delivers wear resistance and edge retention on materials such as aluminum, brass, and copper alloys. The tool measures 1 inch in diameter with a 0.12 inch corner radius, a 2 inch length of cut, and a 4.5 inch overall length. The 3-flute, right-hand spiral geometry runs at a high helix angle of 42 degrees, promoting efficient chip evacuation and a smooth surface finish. Shank diameter is 1 inch with a Weldon flat configuration for secure toolholder engagement.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC milling operations where a controlled corner radius profile is required on non-ferrous workpieces. Its short-length, coarse-pitch design makes it a practical choice for finishing passes in production environments. The centercutting design allows plunge entry, adding versatility in contour and pocket milling applications. It is intended for use with a compatible Weldon-flat toolholder and is classified under the PM-539R series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal construction with TiCN (PVD) coating for extended tool life in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003e0.12 inch corner radius reduces stress concentrations and improves surface finish at workpiece edges\u003c\/li\u003e\n  \u003cli\u003e42-degree high helix angle promotes aggressive chip evacuation and reduced cutting heat\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and prevents slippage in the toolholder\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cutting and flute direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Weldon-flat toolholders.

Verify toolholder bore size matches the 1 inch shank diameter before installation and torque the Weldon flat set screw to the toolholder manufacturer specification. Confirm runout after installation before beginning a cutting pass. Do not exceed the recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.12 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\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 (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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\u003eSeries\u003c\/strong\u003e: PM-539R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 pounds\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: C40359\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51706936787250,"sku":"C40359","price":356.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e03be9fcb9d8d58908d0742d9e20ed5.jpg?v=1788437509","url":"https:\/\/voomisupply.com\/products\/cleveland-c40359-corner-radius-end-mill-1-in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
