Built from powdered metal and coated with a PVD-applied TiCN finish, this tool delivers extended wear resistance in demanding machining environments. It features a 1 inch cutting diameter, a 0.12 inch corner radius, and a 4 inch length of cut, making it well-suited for deeper cavity work and long-reach finishing passes. The right-hand spiral flute geometry and high helix angle promote efficient chip evacuation. Licensed machinists and CNC operators are the primary users of this tooling.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for finishing operations on non-ferrous metals, including aluminum, copper, and similar materials. Its long-reach configuration and coarse pitch make it appropriate for applications requiring extended reach into pockets, slots, or contoured surfaces. The 1 inch Weldon flat shank seats securely in compatible toolholders, providing rigid setup on vertical and horizontal machining centers. The PM-539R series is a recognized Cleveland offering for shops that prioritize consistent surface finish and dimensional accuracy in non-ferrous work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating applied via PVD process for improved hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003ePowdered metal substrate provides consistent grain structure and toughness\u003c\/li\u003e\n\u003cli\u003e0.12 inch corner radius reduces stress concentration at cutting edges\u003c\/li\u003e\n\u003cli\u003eHigh helix, right-hand spiral flutes promote clean chip evacuation in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank ensures positive drive and minimal slippage in toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard toolholders accepting a 1 inch Weldon flat shank.

Before mounting, confirm the toolholder bore and set-screw alignment are compatible with a 1 inch Weldon flat shank. Secure the shank to the manufacturer-recommended clamping torque for the specific toolholder in use. Verify spindle direction is set to right-hand rotation before initiating a cut, and confirm tool runout with a dial indicator after mounting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees (High)\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\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\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 pounds\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: C40369\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720748990770,"sku":"C40369","price":484.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22fb71ac6cc4e29ac4b1a6f0638bbf02.jpg?v=1788568589","url":"https:\/\/voomisupply.com\/products\/cleveland-c40369-corner-radius-end-mill-1in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
