It features a 5\/8-inch diameter with a 0.03-inch corner radius, six flutes, and a 1-7\/8-inch length of cut. The AlTiN physical vapor deposition coating provides thermal resistance and extended tool life when cutting ferrous and hard materials. The KOR6 series geometry uses a close pitch, high-helix spiral flute configuration that promotes chip evacuation and surface finish quality. This tool is single-end and centercutting, allowing plunge entry when required. It is used by machinists and toolroom professionals on CNC mills and machining centers.\u003c\/p\u003e\n\u003cp\u003eThe 6767678 is suited for finishing applications in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The Weldon flat shank provides secure toolholder engagement, reducing pullout risk under high cutting loads. With a 4-inch overall length and 5\/8-inch shank diameter, it is compatible with standard 5\/8-inch collet chucks, shell mill adapters, and Weldon-style holders. It is also listed for use with EM-CV Form AD and EM IN-HSK Form A toolholding systems. The right-hand flute direction and right-hand cutting direction follow standard CNC mill conventions. The submicron carbide grade substrate supports edge retention in abrasive and high-hardness workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03-inch corner radius reduces stress concentration and improves edge life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides oxidation resistance for dry and semi-dry cutting of hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eSix-flute close-pitch design increases feed rate capability and improves surface finish in finishing passes\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide substrate delivers rigidity and edge retention in steel, stainless, cast iron, superalloys, and hard materials\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank ensures positive grip in side-lock and Weldon-style toolholders\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits plunge milling and ramping entry cuts\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 as specified by the manufacturer.

Ensure the machine spindle is fully stopped and the tool path program is confirmed before loading the tool. Seat the Weldon flat fully into the holder bore and torque the set screw to the toolholder manufacturer specification. Verify runout with a dial indicator before cutting, as excessive runout accelerates wear on carbide end mills and degrades surface finish.\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 inch (0.6250 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: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches (0.7500 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: 5\/8 inch (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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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: No\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 Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KOR6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.527 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 6.3 inches\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: 6767678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734239805746,"sku":"6767678","price":477.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e050ff129daa347d109134ebddcc1c6d_ac411a5c-7e26-4e46-87f4-21c894490eae.jpg?v=1788761477","url":"https:\/\/voomisupply.com\/products\/kennametal-6767678-corner-radius-end-mill-5-8-in-6-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
