Built from high speed steel (HSS), it features a 0.4375 inch mill diameter, a 0.8125 inch length of cut, and a 30-degree right-hand spiral helix. The double-end configuration provides two usable cutting ends, extending tool life between changes. With 2 flutes and an uncoated finish, this end mill is suited for controlled material removal where surface finish matters. It belongs to the HD-2B series and is intended for use by machinists and tool-and-die professionals on manual or CNC milling equipment.\u003c\/p\u003e\n\u003cp\u003eThe C42197 is rated for use on cast iron, non-ferrous metals, and steel. The 0.5 inch shank diameter fits standard collets and end mill holders commonly found in both manual knee mills and CNC machining centers. The regular-length designation and 4.125 inch overall length make it appropriate for general-purpose setups without extended reach requirements. This end mill is a finishing tool, not intended for heavy roughing passes. It is commonly used for ball-radius profiling, 3D contouring, and slot finishing where a precise hemispherical tip geometry is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, reducing per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction suited for cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral helix for efficient chip evacuation during finishing cuts\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry provides clearance for finishing passes and contour work\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no coating degradation concerns when regrinding or using with cutting fluids\u003c\/li\u003e\n  \u003cli\u003eHD-2B series regular-length design for standard milling setups without extended reach\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 0.5 inch collet chucks and end mill holders used in milling operations on cast iron, non-ferrous metals, and steel workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist with the machine fully powered down and spindle locked. Ensure the collet or end mill holder is clean and free of debris before seating the shank to the correct depth. Torque the drawbar or collet nut according to the machine manufacturer specifications for the holder type in use. Verify runout with a dial indicator before beginning cuts, as excessive runout will shorten tool life and degrade 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: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eChipbreaker\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: C42197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697949802802,"sku":"C42197","price":146.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7c5f7a5f60fa094fd1c3d359598de3d.jpg?v=1788356217","url":"https:\/\/voomisupply.com\/products\/cleveland-c42197-ball-end-mill-0-4375-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
