With a 0.03-inch cutting diameter and a 3-flute geometry, this tool delivers clean, accurate cuts in tight-tolerance work where rigidity and chip evacuation both matter. The AlTiN coating extends tool life in high-heat environments by providing oxidation resistance and reduced friction at the cutting edge. At 2.5 inches overall length with a 0.125-inch shank, this miniature end mill is built for CNC machining centers, manual mills, and high-speed spindle work where small-diameter precision tooling is required. Installed by machinists and tool room operators across production and prototype shops.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits applications in ferrous and non-ferrous metals, hardened steels, and high-temperature alloys where fine-feature milling is required. The single-end configuration, right-hand cutting direction, and right-hand flute direction make it a standard choice for conventional CNC milling operations. A 30-degree helix angle promotes efficient chip flow and reduced cutting forces, making it well suited for slotting, profiling, and finishing passes on small-scale features. The centercutting capability allows plunge entry into the workpiece without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03-inch cutting diameter for precision small-feature milling\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip evacuation and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides heat and oxidation resistance for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix promotes smooth chip flow and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability at high spindle speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard-stock solid carbide square end mill for CNC machining centers and manual milling machines accepting a 0.125-inch shank diameter collet or tool holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or tool holder matched to the 0.125-inch shank to prevent runout and tool pullout. At this diameter, minimize overhang and verify runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches (1\/4 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\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\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\u003eEnd Type\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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: 0.02 pounds\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: 33630-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51739452080434,"sku":"33630-C3","price":111.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d70c12256c804cf5e3a34b4b274a50d_704c5418-f89b-46e3-80bb-c9e65b6bff08.jpg?v=1788814759","url":"https:\/\/voomisupply.com\/products\/harvey-tool-33630-c3-square-end-mill-0-03-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
