With a 0.5 mm (0.0200 inch) cutting diameter and a 4-flute geometry, this end mill delivers fine surface finishes and efficient chip evacuation in hardened and abrasive materials. The 30-degree helix angle balances cutting efficiency with edge strength at small diameters. An AlTiN (aluminum titanium nitride) coating increases surface hardness and thermal resistance, extending tool life in ferrous metals, stainless steel, and high-temperature alloys. The shank diameter is 0.125 inches, and overall length is 2.5 inches.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and high-speed spindles performing slot milling, profiling, and fine-detail work in mold-making, die work, aerospace component finishing, and medical device manufacturing. The 0.1-inch length of cut makes it appropriate for shallow passes in dense or hardened workpieces. It is a single-end, right-hand cutting tool with a right-hand flute direction. This tool is not centercutting and should not be used for direct plunge operations. Machinists and CNC programmers working with micro tooling in production or prototype environments are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 mm cutting diameter for precision micro-milling applications\u003c\/li\u003e\n\u003cli\u003e4-flute design supports improved surface finish and chip removal\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated hardness and heat resistance for ferrous and alloy steels\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances edge strength with cutting efficiency\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single-end configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production end mill for CNC machining centers and high-speed spindles accepting a 0.125-inch shank diameter collet or toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and the tool changer or spindle is at rest before inserting or removing the tool. Use a precision collet or end mill holder rated for the 0.125-inch shank diameter and verify runout with a dial indicator before beginning cuts. Because this tool is not centercutting, do not program direct axial plunge moves — use ramping or helical entry toolpaths instead.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 mm (0.0200 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 0.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\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\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 834120-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51747228811570,"sku":"834120-C3","price":77.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8812d2b2470bfaa489e415e80bcb36_d8a7017b-11bc-4209-9f41-d3eb4c9d9573.jpg?v=1788877759","url":"https:\/\/voomisupply.com\/products\/harvey-tool-834120-c3-square-end-mill-0-5mm-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
