Built to the HPHV series specification, it carries a 0.625 inch mill diameter with a 0.03 inch corner radius and four right-hand spiral flutes with a high helix angle of 38 degrees. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting hard and abrasive workpiece materials. At 4 inches overall length with a 2.125 inch length of cut, this is a long-reach, single-end centercutting tool suited for deep-cavity and profiling operations. It installs in standard 5\/8 inch tool holders and accepts Weldon flat shank clamping. Machining professionals in job shops, production facilities, and aerospace or moldmaking environments rely on this geometry for both roughing and finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use with steel, stainless steel, cast iron, and hard materials, corresponding to material application codes P, M, K, and H. The extended reach and long flute length make it well-suited for machining deep slots, pockets, and contoured walls where shorter tools cannot reach. It is compatible with EM-CV Form AD and EM IN-HSK Form A tooling systems as specified by the manufacturer. Normal pitch and a right-hand cutting direction provide consistent chip evacuation across supported workpiece materials. This tool is sold individually with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03 inch corner radius reduces stress concentration at cutting edges and improves surface finish on profiled walls\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides elevated-temperature hardness for cutting steel, stainless steel, cast iron, and hard materials\u003c\/li\u003e\n  \u003cli\u003eFour right-hand spiral flutes with 38-degree high helix angle for aggressive chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry and ramp-in moves without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with 5\/8 inch diameter shank ensures secure clamping and reduced tool pull-out risk\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 2.125 inch length of cut supports deep-pocket and long-reach machining operations\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade construction provides uniform hardness and fracture resistance across the cutting zone\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems per manufacturer specification.

Power down and lock out the machine spindle before loading or removing the end mill. Seat the Weldon flat fully in the holder and torque the set screw to the toolholder manufacturer specification before engaging the spindle. Do not exceed the tool overhang or depth-of-cut parameters recommended for the HPHV series for the target workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 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: 2.125 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: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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\u003eWeight\u003c\/strong\u003e: 0.265 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: 4067266\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732054245682,"sku":"4067266","price":585.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4d2c371aa097896a385e795d9c1c594_42ca43e9-eb7d-4186-a979-77bf2db6aaaa.jpg?v=1788738701","url":"https:\/\/voomisupply.com\/products\/kennametal-4067266-corner-radius-end-mill-5-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
