It carries a 0.75-inch mill diameter, a 1.5-inch length of cut, and a 0.03-inch corner radius that protects the cutting edge and reduces chipping at the tool tip. The AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and extended tool life at elevated cutting temperatures. With five flutes and a high-helix spiral flute geometry, it supports both roughing and finishing operations in a single tool. Licensed machinists and CNC programmers working in job shops, aerospace, and precision manufacturing will find this tool well matched to tight-tolerance applications in hard and exotic alloys.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits into standard toolholders accepting a 0.75-inch shank with a Weldon flat. The 4-inch overall length and short length-type classification make it suitable for rigid setups with minimal overhang. Compatible toolholding systems listed by Kennametal include the EM-CV Form AD and EM IN-HSK Form A holders. It is cataloged under the UCDE series, which targets high-performance finishing and semi-finishing in production environments where surface finish and edge integrity are critical. Right-hand cutting direction and right-hand flute orientation are standard for conventional CNC machining center setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03-inch corner radius reduces edge chipping and extends tool life in hardened materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating delivers thermal and oxidation resistance for dry and semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003eFive-flute, high-helix spiral geometry supports both roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and prevents tool pullout under heavy cuts\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade maintains edge sharpness in steel, stainless, cast iron, and hard materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end construction; not centercutting  -  requires a pre-drilled entry point or ramping strategy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible toolholding systems specified by Kennametal include EM-CV Form AD and EM IN-HSK Form A holders. Designed for CNC machining centers using 3\/4-inch bore toolholders with Weldon flat drive. Intended workpiece materials are steel (P), stainless steel (M), cast iron (K), and hard materials (H) per ISO material classification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Confirm the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the Weldon flat against the setscrew in the toolholder and torque the setscrew per the toolholder manufacturer specification. Because this end mill is not centercutting, do not plunge directly into solid material  -  use a pre-drilled hole, helical interpolation, or a ramping entry to begin the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: UCDE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4048738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744434127154,"sku":"4048738","price":900.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/daadb2cd38e98818b8d41f2339b62296_93197d54-8ffe-458f-b9c0-664431ed030e.jpg?v=1788856452","url":"https:\/\/voomisupply.com\/products\/kennametal-4048738-corner-radius-end-mill-3-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
