With a 0.5-inch mill diameter, a 0.03-inch corner radius, and a 4-flute configuration, this tool delivers both roughing and finishing capability in a single pass. The AlTiN PVD coating provides heat resistance and extended tool life under high-speed cutting conditions. The HPHV series designation indicates a high-performance, high-velocity geometry engineered to maintain edge integrity in difficult workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual mills in job shops, production machining, and toolroom environments. The extended-reach geometry with a 1.625-inch length of cut makes it suitable for slotting, profiling, and shoulder milling in pockets with depth requirements that standard-length tools cannot address. The Weldon flat shank provides positive drive engagement in collet holders and Weldon-style tool holders, reducing pullout risk under heavy cuts. Compatible holder systems noted in product data include EM-CV Form AD and EM IN-HSK Form A toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03-inch corner radius reduces stress concentration and extends tool life versus sharp-corner end mills\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating improves heat resistance for dry or near-dry cutting in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade provides hardness and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eExtended-reach length of cut (1.625 inches) for deep pocket and shoulder milling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank for positive drive engagement and reduced pullout\u003c\/li\u003e\n  \u003cli\u003eSingle-end, centercutting design allows plunge entry and full-slot milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute geometry suitable for standard spindle rotation\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 toolholders as noted in product specifications.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to the toolholder specification before running. Verify runout with a dial indicator after setup and before initiating a cut, particularly given the tight shank diameter tolerance of +0.00000 \/ -0.00043 inches.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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: 1.625 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: 0.5 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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eLength Type\u003c\/strong\u003e: Long \/ Extended Reach\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\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\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\u003ePrimary Workpiece Materials\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\u003eWeight\u003c\/strong\u003e: 0.276 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: 4071924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730324619570,"sku":"4071924","price":350.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5fd943156fd6f7bfd8e884fe97ca1c6.jpg?v=1788715377","url":"https:\/\/voomisupply.com\/products\/kennametal-4071924-corner-radius-end-mill-0-5in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
