With a 5\/16-inch (0.3125-inch) mill diameter and a 0.03-inch corner radius, this tool produces accurate edge profiles while reducing stress concentration at corners. The 4-flute, AlTiN-coated design supports both roughing and finishing operations in a single tool, making it well suited for shops running steel, stainless steel, cast iron, and hard materials. The submicron carbide grade and high-helix geometry of the HPHV series deliver thermal resistance and chip evacuation efficiency at elevated cutting speeds.\u003c\/p\u003e\u003cp\u003eThis end mill is built for CNC machining centers running ferrous and hard-material workpieces. It is rated for primary use in steel, stainless steel, cast iron, and hard material (ISO material codes P, M, K, and H). The extended-reach configuration, with a 1\/2-inch length of cut and 2-inch overall length, accommodates deeper pockets and longer reach applications without requiring a stub-reach tool change. Single-end construction and right-hand cutting and flute direction make this a standard drop-in for most right-hand spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03-inch corner radius reduces stress and extends tool life at pocket corners\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides heat resistance for dry and high-speed cutting in ferrous materials\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes support both roughing and finishing in a single pass\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade delivers consistent edge integrity in hard materials\u003c\/li\u003e\n\u003cli\u003eExtended-reach geometry with 1\/2-inch reach length suits deeper pocket milling\u003c\/li\u003e\n\u003cli\u003eCompatible with hydraulic sleeves and ER collet systems for rigid, low-runout setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with HC 1\/2 through HC 1-1\/4 hydraulic sleeves (inch bore, inch shank), HC 20M through HC 32M hydraulic sleeves (metric sleeve, inch bore), and ER single angle standard collets.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tools. Verify collet or hydraulic sleeve bore size matches the 5\/16-inch shank before clamping. Confirm tool projection and runout with a dial indicator before initiating a cut, particularly in extended-reach setups where deflection risk increases.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\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\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\u003eHelix Style\u003c\/strong\u003e: High\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\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\u003eSeries\u003c\/strong\u003e: HPHV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 4047742\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728754540850,"sku":"4047742","price":126.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4d2c371aa097896a385e795d9c1c594_84782c87-16b1-45e3-88eb-665090783d63.jpg?v=1788695868","url":"https:\/\/voomisupply.com\/products\/kennametal-4047742-corner-radius-end-mill-5-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
