With a 1.8 mm (0.0710 inch) cutting diameter and a 4-flute geometry, it delivers smooth chip evacuation and fine surface finishes in ferrous and non-ferrous materials. The AlTiN coating provides heat resistance and extended tool life at elevated cutting temperatures. A 30-degree helix angle balances cutting efficiency with edge stability. This tool is installed and operated by machinists and CNC programmers working in precision manufacturing, tool-and-die, mold making, and aerospace component production.\u003c\/p\u003e\u003cp\u003eThis end mill suits small-feature milling applications where tight tolerances and fine detail are required. The 0.213 inch length of cut and 1.5 inch overall length make it well suited for shallow pocket milling, slotting, and contouring in compact workpiece geometries. The 0.125 inch (1\/8 inch) shank diameter fits standard ER collets and other common toolholding systems used on CNC machining centers and high-speed spindles. Center-cutting geometry allows plunge entry without a pre-drilled starting hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability at high feed rates\u003c\/li\u003e\n\u003cli\u003eAlTiN coating enhances heat resistance and reduces built-up edge in hard materials\u003c\/li\u003e\n\u003cli\u003e4-flute design improves surface finish and allows higher feed-per-tooth values\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix balances axial cutting forces with chip flow\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 1\/8 inch (0.125 inch) collet toolholding systems on CNC machining centers and high-speed milling spindles.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before inserting or removing the tool from the collet. Ensure the shank is fully seated and the collet nut is torqued according to the toolholder manufacturer specifications. Verify runout at the tool tip with a dial indicator before beginning a production run to prevent premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.8 mm (0.0710 inches)\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: 0.213 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 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\/Finish\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\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: 0.01 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: 73071-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51736969740594,"sku":"73071-C3","price":49.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b439e4d9750d2d519b94c7aaf8826d59_6f3ea8a7-fda7-4b88-a78f-488cf9f26bb0.jpg?v=1788782495","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73071-c3-square-end-mill-1-8mm-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
