It features a TiCN (titanium carbonitride) coating that improves wear resistance and extends tool life compared to uncoated HSS tooling. The cutting diameter is 5\/8 inches with a matching 5\/8 inches straight shank that includes a Weldon flat for secure tool holding. Length of cut is 1-5\/16 inches, overall length is 3-1\/4 inches, and the helix angle is 30 degrees. This end mill is centercutting, allowing plunge entry into the workpiece. It is used by machinists and tool-and-die professionals in CNC and manual milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing cuts on cast iron, steel, and non-ferrous metals. The Weldon flat shank is compatible with standard end mill holders and side-lock holders used in vertical mills and machining centers. The 2-flute configuration and keyway geometry make it appropriate for slotting, keyway cutting, and profiling operations where chip clearance and side-wall finish are priorities. It is part of the CLEVELAND HG-2K series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN finish for improved hardness and wear resistance over uncoated HSS\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilled entry\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting action and chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeldon flat on shank ensures positive grip in side-lock holders\u003c\/li\u003e\n\u003cli\u003e2-flute geometry provides chip clearance for slotting and keyway operations\u003c\/li\u003e\n\u003cli\u003eFinishing grade material removal for tight-tolerance slot and keyway work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 5\/8 inches end mill holders and side-lock Weldon-flat tool holders in vertical milling machines and CNC machining centers.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank fully into the holder and tighten the set screw against the Weldon flat to the holder manufacturer's torque specification. Inspect the cutting edges and TiCN coating for chips or wear before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight with Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-2K\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C38971\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697101209906,"sku":"C38971","price":134.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c18c31185670adeb94c5a45eda319977_ecd7597e-2284-49b1-b093-851aee2816dd.jpg?v=1788349403","url":"https:\/\/voomisupply.com\/products\/cleveland-c38971-keyway-end-mill-2-flute-hss-ticn-5-8in","provider":"Voomi Supply","version":"1.0","type":"link"}
