Built with three flutes and a right-hand cutting direction, it delivers efficient chip evacuation and a clean square shoulder profile. The 0.375-inch shank diameter and single-end configuration make it a standard fit for CNC machining centers and manual mills alike. Manufactured to the K600 material grade specification, this end mill is supplied in a bright, uncoated finish — suitable for applications where coating-induced dimensional buildup is a concern or where the base carbide substrate performs best without an additional layer.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose milling, slotting, and profiling tasks in machine shops, production environments, and toolrooms. The center-cutting capability allows direct plunge entry into a workpiece, giving machinists flexibility for both plunge and ramping operations. The fixed helix geometry and standard index configuration provide predictable cutting performance across a range of milling applications. It is typically installed and used by CNC machinists, tool-and-die makers, and production machinists working in light to medium-duty cutting conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThree-flute solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e0.375-inch shank diameter for compatibility with standard toolholders\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — K600 material grade solid carbide substrate\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration for straightforward toolholder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers, knee mills, and manual milling machines equipped with toolholders accepting a 0.375-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with end mill toolholder torque procedures and runout verification. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing end mills. Seat the shank fully into the toolholder collet or end mill holder before tightening to manufacturer specifications. Verify runout with a dial indicator before beginning cutting operations to avoid premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: K600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 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: 3870469\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733025358130,"sku":"3870469","price":133.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50afcd3c9ef7f9f7abcbaa8b7442d485.jpg?v=1788750721","url":"https:\/\/voomisupply.com\/products\/kennametal-3870469-square-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
