Built from powdered metal (PM) with a TiCN PVD coating, this tool delivers wear resistance and edge retention on materials such as aluminum, brass, and copper alloys. It measures 3\/4 inches in cutting diameter with a 1-5\/8 inches length of cut and a 0.09 inches corner radius that reduces stress concentrations at pocket floors and shoulders. With a 3.875 inches overall length and a 3\/4 inches Weldon flat shank, the C40348 is designed to seat securely in compatible toolholders. Licensed machinists and CNC operators in production and job-shop environments are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finishing passes in milling applications involving non-ferrous metals. The high-helix, three-flute geometry promotes chip evacuation and surface finish quality at elevated feed rates. The coarse pitch and right-hand spiral fluting support consistent cutting action in both conventional and climb milling setups. The Weldon flat shank provides positive drive and reduces the risk of pull-out in standard side-lock toolholders. The PM-539R series designation indicates Cleveland's powdered metal substrate line, which offers improved toughness compared to standard high-speed steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.09 inches corner radius reduces notching and stress at workpiece corners during finishing passes\u003c\/li\u003e\n  \u003cli\u003eTiCN PVD coating improves surface hardness and wear resistance on non-ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePowdered metal substrate provides enhanced toughness and grindability over conventional HSS\u003c\/li\u003e\n  \u003cli\u003e3-flute, high-helix geometry promotes efficient chip evacuation in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank ensures positive engagement in side-lock and set-screw toolholders\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Weldon flat toolholders accepting a 3\/4 inches shank diameter.

Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the Weldon flat fully against the set screw in the toolholder before tightening to manufacturer torque specifications for the holder. Confirm runout with a dial indicator after installation to protect edge life and surface finish quality.\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 inches (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\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (0.3543 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eHelix Style\u003c\/strong\u003e: 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\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\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: 0.4 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: C40348\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698935529778,"sku":"C40348","price":213.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c3233d5d4e33c2fef398e87f3616753.jpg?v=1788370046","url":"https:\/\/voomisupply.com\/products\/cleveland-c40348-corner-radius-end-mill-3-4-in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
