It carries a 0.03 inch corner radius on a 1\/4 inch diameter cutting head with 4 flutes and a high helix geometry. The AlTiN PVD coating provides thermal resistance and wear protection at elevated cutting temperatures. At 4 inches overall length with a 1-1\/4 inch extended reach, this tool is built for long-reach applications where standard-length end mills cannot access the cut. It is suited for both roughing and finishing operations in a single tool. Licensed machinists and CNC programmers in production and job-shop environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits into the Kennametal UADE series and is sized for use 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 toolholders. The 1\/4 inch straight cylindrical shank accepts standard collet and hydraulic chuck systems in that bore size. It is a single-end, right-hand cut, right-hand flute tool classified for long-length reach work. Material removal type covers both roughing and finishing passes, reducing tool changes in multi-stage operations on hard and exotic workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN PVD coating for heat resistance and extended tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius reduces stress concentration and improves surface finish at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eExtended reach geometry: 1-1\/4 inch reach length and 0.235 inch neck diameter for deep-pocket and long-reach cuts\u003c\/li\u003e\n  \u003cli\u003e4-flute, high-helix spiral flute design supports both roughing and finishing in a single pass\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade substrate for improved edge toughness in hard and interrupted cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use 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.

The machine spindle must be at a complete stop and the control placed in an estop or tool-change state before inserting or removing the end mill. Use the appropriate torque wrench for collet nuts or hydraulic chuck activation per the toolholder manufacturer specifications. Inspect the shank and collet bore for chips or contamination before seating to prevent runout.\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: UADE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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: 4068216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730238505266,"sku":"4068216","price":188.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67864b154ced85566c06aa73e9362e12.jpg?v=1788713879","url":"https:\/\/voomisupply.com\/products\/kennametal-4068216-corner-radius-end-mill-1-4-inch-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
