The cutter measures 0.067 inches in diameter with a 0.201-inch length of cut, making it well suited for fine detail work and small-feature profiling. A 30-degree helix angle promotes efficient chip evacuation while reducing cutting forces. The AlTiN coating improves heat resistance and extends tool life across a range of demanding workpiece materials. With four flutes and a single-end, centercutting design, this end mill handles both plunge and peripheral cuts. It weighs 0.01 pounds and is part of the Harvey Tool Miniature End Mills Stub and Standard series.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. Primary workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and carbon fiber reinforced polymer (CFRP) materials. The 1\/8-inch shank diameter fits standard collet chucks and toolholders commonly found in die and mold shops, prototype machining environments, and aerospace component manufacturing. The 1.5-inch overall length keeps deflection minimal at this diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.067-inch cutting diameter for fine-detail and small-feature work\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides heat resistance and extends tool life on ferrous and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4-flute, single-end, centercutting geometry allows plunge entry and peripheral milling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability at miniature scales\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute configuration for standard CNC spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/8-inch collet chucks and toolholders.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or removing the tool. At this diameter, runout control is critical — use a high-precision collet and verify TIR before cutting. Follow the tool manufacturer's recommended speeds and feeds for the target workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.067 inches (1.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.201 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, CFRP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 73067-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732559659314,"sku":"73067-C3","price":49.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b439e4d9750d2d519b94c7aaf8826d59_7db7863d-5378-439f-9089-9e57c67f3ee4.jpg?v=1788744449","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73067-c3-square-end-mill-0-067-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
