With a 0.0310-inch cutting diameter and a 0.125-inch length of cut, this tool is built for fine-detail work in tight geometries. Three flutes and a 30-degree helix angle deliver a balance of chip evacuation and surface finish quality. The AlTiN coating provides thermal resistance and extended tool life when cutting hard or abrasive materials. At 2.5 inches overall length and a 0.125-inch shank diameter, this end mill fits standard collet systems found on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill suits precision CNC milling operations in aerospace, medical device, die and mold, and general metalworking environments. The small diameter makes it appropriate for fine-feature slotting, profiling, and pocketing in ferrous and non-ferrous metals. Centercutting capability allows for direct plunge entry. Right-hand cut and right-hand flute geometry are standard for conventional milling setups. The 0.0310-inch diameter falls within the 0.100- to 0.200-inch length-of-cut range class, making it well suited for micro-milling tasks requiring tight tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0310-inch cutting diameter for fine-feature and micro-milling work\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances chip flow and finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute geometry for standard CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-installation end mill for standard 0.125-inch collet or end mill holder systems on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC setup technicians using an appropriate collet or end mill holder sized for the 0.125-inch shank. Ensure the machine spindle is fully stopped and locked out before tool changes. Confirm runout with a dial indicator after seating to avoid premature wear or breakage on this small-diameter tool. Follow the machine manufacturer and tooling guidelines for speed and feed parameters appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0310 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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: 2.5 inches\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: 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: Yes\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\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: 888431-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51744926892338,"sku":"888431-C3","price":69.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8812d2b2470bfaa489e415e80bcb36_45c5c994-ec35-40c1-a120-0ee1cba538de.jpg?v=1788862323","url":"https:\/\/voomisupply.com\/products\/harvey-tool-888431-c3-square-end-mill-0-031-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
