With a 0.0550-inch cutting diameter and a 0.165-inch length of cut, this tool handles tight-tolerance profiling, slotting, and contouring in small-part applications. The four-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating increases surface hardness and thermal resistance, extending tool life in ferrous and hardened materials. This end mill is used by machinists and tool-and-die professionals in CNC milling operations where small diameters and precise geometry are critical.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision CNC milling of small features in ferrous metals, hardened steels, and similar materials where tool rigidity and coating performance are essential. The 0.125-inch shank diameter fits standard collets and end mill holders commonly found on vertical machining centers and CNC routers. With a 1.5-inch overall length and a non-extended-reach design, it maintains rigidity during light finishing and fine detail passes. Typical users include machinists, mold makers, and precision fabricators working in job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0550-inch cutting diameter for small-feature and micro-milling applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating enhances thermal resistance and extends tool life in hardened materials\u003c\/li\u003e\n  \u003cli\u003e4-flute design with 30-degree helix angle for efficient chip evacuation and finish quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration standard for CNC milling setups\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry into workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 0.125-inch (1\/8-inch) collets and end mill holders on CNC vertical machining centers, CNC routers, and manual mills equipped for small-diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or tool holder to the recommended engagement depth and torque the collet nut according to the holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as small-diameter end mills are sensitive to even minor tool holder runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.0550 inches (1.4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.165 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\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\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73055-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51740236710194,"sku":"73055-C3","price":46.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b439e4d9750d2d519b94c7aaf8826d59_50191c69-6082-4c10-9550-913439dc4ae6.jpg?v=1788823677","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73055-c3-square-end-mill-0-0550-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
