Designed for use on steel, stainless steel, cast iron, and hard materials, this single-end tool features a 1\/4 inch cutting diameter with a 0.015 inch corner radius that protects the cutting edge and extends tool life. The 5-flute geometry combined with a high-helix spiral flute design supports both roughing and finishing operations in a single tool. An AlTiN PVD coating delivers thermal resistance and hardness at elevated cutting speeds, making this end mill well suited for dry or near-dry machining environments on submicron-grade carbide substrate.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for CNC machining centers and milling machines used in precision metalworking shops, job shops, and production environments. The 1\/2 inch length of cut and 1-1\/4 inch reach length allow access into cavities and pockets where standard-length tools cannot reach. The straight cylindrical 1\/4 inch shank is compatible with Kennametal HC 1\/2 through HC 1-1\/4 hydraulic sleeves with inch bores and HC 20M through HC 32M hydraulic sleeves metric with inch bores. This tool is appropriate for machinists and CNC programmers working with ferrous and hard workpiece materials in short-to-medium reach setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide substrate for rigidity and wear resistance in hard-material applications\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for thermal protection and extended tool life at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e5-flute design supports both roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eHigh-helix spiral flute geometry promotes chip evacuation and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius protects cutting edge corners and reduces chipping\u003c\/li\u003e\n  \u003cli\u003eExtended reach configuration at 1-1\/4 inch reach length for cavity and pocket access\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Kennametal HC 1\/2 through HC 1-1\/4 hydraulic sleeves with inch bores and HC 20M through HC 32M hydraulic sleeves metric with inch bores.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before inserting or removing the end mill from the holder. Verify runout with a dial indicator after seating the tool in the hydraulic sleeve to confirm proper engagement before beginning a cut. Consult the machining center manufacturer guidelines and applicable shop safety procedures when setting cutting parameters for hard or abrasive workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.2350 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1-1\/4 inch (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (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: Straight Cylindrical\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\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\u003eSeries\u003c\/strong\u003e: UCDE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4048742\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749892751666,"sku":"4048742","price":213.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/918ea443806af0c0abfc31daf8708890.jpg?v=1788911817","url":"https:\/\/voomisupply.com\/products\/kennametal-4048742-corner-radius-end-mill-1-4-in-5-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
