It features a 0.5 inch mill diameter, a 1.25 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in interrupted cuts. The four-flute, right-hand spiral geometry with a 36-degree helix angle promotes efficient chip evacuation while maintaining rigidity. An AlTiN PVD coating provides thermal resistance and hardness, making this tool suitable for dry or semi-dry machining. Machinists and tooling technicians install this end mill in CNC milling centers and manual mills for roughing and finishing operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for both roughing and finishing passes in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its center-cutting capability allows direct plunge entry without a pre-drilled hole. The straight cylindrical shank at 0.5 inch diameter fits standard end mill toolholders. The 3.25 inch overall length provides adequate reach for common milling operations without sacrificing rigidity. It is a single-end tool from the KENNAMETAL H1TE series, built around a submicron carbide grade for edge retention in difficult alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces edge chipping and extends tool life in steel and hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides high thermal resistance for dry and semi-dry machining\u003c\/li\u003e\n\u003cli\u003eFour right-hand flutes with 36-degree helix for balanced chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide grade maintains edge sharpness in superalloys and titanium\u003c\/li\u003e\n\u003cli\u003eRoughing and finishing capable in a single tool across multiple material groups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with standard end mill toolholders accepting a 0.5 inch straight cylindrical shank.

Power down and lock out the spindle before mounting or removing the end mill. Seat the shank fully and evenly in the toolholder to the recommended gauge depth and torque the retention mechanism per the toolholder manufacturer specification. Inspect the cutting edges and coating for chips or damage before each use, and confirm runout is within acceptable tolerance before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 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\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\u003eHelix Angle\u003c\/strong\u003e: 36 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\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 End\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\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, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 inches L x 0.98 inches W x 0.98 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 6676424\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741459284274,"sku":"6676424","price":273.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07a49ed9e00b7aa9b89cab4141d7a4b9_e2662e6d-456b-4dad-865f-bc2059b400a8.jpg?v=1788831605","url":"https:\/\/voomisupply.com\/products\/kennametal-6676424-corner-radius-end-mill-0-5in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
