Built to Series PM-538R specifications, it features a 1-inch cutting diameter, a 2-inch length of cut (LOC), and a 4.5-inch overall length (OAL). The tool uses a TiCN (Titanium Carbonitride) coating to reduce friction and extend tool life in abrasive materials. With 3 spiral flutes and a 42-degree helix angle, it delivers efficient chip evacuation and smooth surface finishes. The centercutting design allows plunge milling operations. The 1-inch shank diameter provides rigid tool holding in standard end mill holders.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining operations in metalworking environments including job shops, production floors, and tool rooms. The coarse pitch and right-hand cutting and flute direction make it appropriate for conventional and climb milling on ferrous and non-ferrous metals. The TiCN coating performs well in materials such as alloy steels, cast iron, and hardened workpieces where tool wear is a primary concern. It is installed by machinists and CNC operators in vertical and horizontal machining centers as well as manual knee mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating reduces wear and friction for extended tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e42-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003e3 spiral flutes with coarse pitch suited for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eSeries PM-538R construction for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fit for 1-inch end mill holders and collet chucks used in CNC machining centers and manual milling machines requiring a 1-inch shank.\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 into a clean, properly sized end mill holder or collet chuck and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the tool for runout with a dial indicator before machining. Never exceed the recommended depth of cut or feed rate for the workpiece material and machine spindle rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eSeries\u003c\/strong\u003e: PM-538R\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: C40021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51721025290546,"sku":"C40021","price":445.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/503d6778a3981be5a4541bf4e694ae20.jpg?v=1788572442","url":"https:\/\/voomisupply.com\/products\/cleveland-c40021-corner-radius-end-mill-1-in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
