With a 5\/8-inch mill diameter, a 0.015-inch corner radius, and four flutes in a right-hand spiral configuration, this tool delivers both roughing and finishing capability in a single pass. The AlTiN PVD coating provides thermal resistance and hardness at elevated cutting temperatures. At 3.5 inches overall length with a 3\/4-inch length of cut, this short-length geometry reduces deflection and supports aggressive feed rates in steel, stainless steel, cast iron, and hard materials. It belongs to the HPHV series and features extended reach geometry with a Weldon flat shank for positive drive in the spindle.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers in job shops, production facilities, and tool rooms working primarily with ferrous and hard materials. The centercutting design allows plunge entry as well as conventional peripheral and slot milling. It is appropriate for applications requiring a controlled corner radius to reduce stress concentrations at workpiece corners, particularly in die and mold work, aerospace components, and precision part machining in steel and stainless steel. Compatible toolholding interfaces noted in supplier data include EM-CV Form AD and EM IN-HSK Form A holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for high-temperature cutting in steel, stainless steel, cast iron, and hard material grades P, M, K, and H\u003c\/li\u003e\n  \u003cli\u003e0.015-inch corner radius reduces chipping at workpiece edges and extends tool life versus sharp-corner end mills\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive rotational drive and minimizes slippage under heavy load\u003c\/li\u003e\n  \u003cli\u003eHPHV series high-helix spiral flute design promotes chip evacuation and smooth surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with EM-CV Form AD and EM IN-HSK Form A toolholding systems.

Confirm the Weldon flat is properly aligned with the toolholder setscrew before tightening to the holder manufacturer's specified procedure. Inspect the AlTiN coating and cutting edges for chips or wear before mounting; a damaged edge on carbide tooling can fracture under load. Follow the machine tool manufacturer's runout tolerance specifications and verify tool projection length before initiating a new program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 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\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\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 \/ -0.00043 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HPHV\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: 1.087 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: 4067239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737984827698,"sku":"4067239","price":555.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4d2c371aa097896a385e795d9c1c594_e711b5ad-65b6-43a3-a257-6484494ff762.jpg?v=1788795453","url":"https:\/\/voomisupply.com\/products\/kennametal-4067239-corner-radius-end-mill-5-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
