It features a 0.500 inch diameter, a 1.000 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentrations and extends tool life at the cutting edge. The 6-flute, close-pitch geometry combined with a 38-degree high helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN PVD coating provides thermal resistance and hardness at elevated cutting temperatures, making this tool well suited for dry or semi-dry machining. Licensed machinists and CNC operators working in job shop or production environments install and run this tool in standard end mill toolholders.\u003c\/p\u003e\u003cp\u003eThis end mill is built for finishing cuts in steel, stainless steel, superalloys, and hard materials. The extended reach configuration, with a 1.325 inch reach length and 3.000 inch overall length on a 0.500 inch straight cylindrical shank, allows access to features with moderate depth requirements. It is a single-end, centercutting design with right-hand flute direction and right-hand cutting direction. The submicron carbide grade supports cutting in difficult-to-machine materials where edge stability and wear resistance are critical. It is part of KENNAMETAL Series HA3R, designed for precision finishing operations on CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300 inch corner radius reduces edge chipping and improves surface finish on finished workpiece corners\u003c\/li\u003e\n\u003cli\u003e6-flute close-pitch design increases feed rates and productivity in finishing applications\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating delivers high-temperature hardness and oxidation resistance for steel and superalloy cutting\u003c\/li\u003e\n\u003cli\u003e38-degree high helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade provides superior edge toughness in hard and abrasion-resistant workpiece materials\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry, increasing application flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill toolholders.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 0.500 inch straight cylindrical shank fully into the toolholder to the recommended gauge length before tightening. Verify runout after clamping, as excessive runout accelerates wear on this close-pitch, multi-flute geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.325 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: 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\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium, Hard Material\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\u003eSeries\u003c\/strong\u003e: HA3R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 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: 7077618\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743313330482,"sku":"7077618","price":252.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28bb9bc7e8d526b80c22559ac2b1a867_2bca4cc5-f13d-4b80-bff2-d68a70a95926.jpg?v=1788845508","url":"https:\/\/voomisupply.com\/products\/kennametal-7077618-corner-radius-end-mill-1-2-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
