It features a 1\/4 inch diameter with a 0.06 inch corner radius, a 4-flute spiral geometry with right-hand cutting direction, and a high-helix design that promotes efficient chip evacuation. The AlTiN PVD coating provides thermal and wear resistance, making this tool well-suited for dry or semi-dry cutting in hard and abrasive workpiece materials. With a 2.5 inch overall length and a 3\/4 inch length of cut, it is designed for both roughing and finishing operations. Machinists and CNC operators in production and job shop environments install this tool using standard collet or hydraulic toolholding systems.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It performs in applications where a sharp corner break or radius blend is required at the bottom of a feature. The single-end, centercutting configuration allows plunge entry and full slot cutting. Extended reach geometry supports access to deeper pockets while maintaining rigidity. It is compatible with HC 1\/2 through HC 1-1\/4 hydraulic sleeves with inch bores, HC 20M through HC 32M hydraulic sleeves metric with inch bores, and HC-CV Form AD toolholding systems as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade construction for hardness and edge retention in difficult materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e0.06 inch corner radius reduces stress concentration and improves part surface finish\u003c\/li\u003e\n\u003cli\u003e4-flute, high-helix spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC spindle operation\u003c\/li\u003e\n\u003cli\u003eExtended reach geometry provides access to deeper features without sacrificing stability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with HC 1\/2 through HC 1-1\/4 hydraulic sleeves with inch bores, HC 20M through HC 32M hydraulic sleeves metric with inch bores, and HC-CV Form AD toolholding.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before inserting or removing the end mill. Use the appropriate collet or hydraulic sleeve matching the 1\/4 inch straight-cylindrical shank diameter and verify runout with a dial indicator before production cutting. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth-of-cut parameters specific to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: UADE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.276 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4079288\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727848571186,"sku":"4079288","price":114.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4d2c371aa097896a385e795d9c1c594_9e8ab92e-3bfc-45fb-9c11-10830f24a158.jpg?v=1788683473","url":"https:\/\/voomisupply.com\/products\/kennametal-4079288-corner-radius-end-mill-1-4-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
