With a 0.0393-inch (1 mm) cutting diameter and a 0.1575-inch (4 mm) length of cut, this tool is built for fine detail work and tight-tolerance slotting, profiling, and contouring. The TiAlN coating extends tool life in high-temperature cutting environments by reducing heat transfer into the substrate. Three flutes provide a balance between chip evacuation and edge strength at small diameters. The 0.1181-inch (3 mm) shank diameter fits standard collet chucks used on CNC machining centers and high-speed spindles. Material grade KC633M identifies this as part of a formulation suited for demanding cut conditions.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous metals, hardened steels, and similar materials where a small-diameter, high-performance tool is required. The centercutting geometry allows plunge milling in addition to peripheral cutting. Right-hand cut with right-hand spiral flutes makes it compatible with standard spindle rotation on conventional and CNC vertical mills. It is typically used in tool rooms, production shops, and precision machining environments where small-feature work demands tight runout control and consistent edge geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0393-inch (1 mm) cutting diameter for fine-detail and small-feature milling\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for extended tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry balances chip clearance with cutting edge strength\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction in grade KC633M for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill replacement for CNC machining centers and manual mills using a 0.1181-inch (3 mm) shank collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully in a properly sized collet or end mill holder and torque the drawbar or collet nut according to the spindle manufacturer specifications. Verify runout with a dial indicator before cutting to protect the tool and workpiece at this diameter. Inspect the cutting edges for chips or wear before each use, as small-diameter carbide tools are brittle and sensitive to side loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.0393 inches (1 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1575 inches (4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1181 inches (3 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: KC633M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01543 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 6146906\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744976077106,"sku":"6146906","price":61.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7397c69f4df5719569970a13ba36ae31_cda9f513-700a-424f-933c-63ede6240001.jpg?v=1788862859","url":"https:\/\/voomisupply.com\/products\/kennametal-6146906-square-end-mill-0-0393in-3-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
