With a 5\/64 inch (0.0780 inch) mill diameter and four flutes, it delivers clean, accurate cuts in a compact profile suited for fine-detail work. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. A 30-degree helix angle balances chip evacuation with cutting stability. This tool is installed by CNC machinists and toolroom operators working on mills, machining centers, and related equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for tight-tolerance slotting, profiling, and peripheral milling on small-feature workpieces. The centercutting geometry allows direct plunge entry, expanding its usefulness across a range of toolpaths. The 1\/8 inch shank diameter fits standard collets and toolholders common in small-diameter end mill setups. Right-hand cut and right-hand flute configuration follow conventional spindle rotation standards on most CNC platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for high-temperature oxidation resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge cutting without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute geometry for use with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eFour-flute configuration increases feed rate capability over two- and three-flute alternatives\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 CNC machining centers and manual mills accepting a 1\/8 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 toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Seat the shank fully within the collet or toolholder to the recommended gauge line and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.0780 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 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\u003eFinish\/Coating\u003c\/strong\u003e: AlTiN\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\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\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: 826878-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51749413388594,"sku":"826878-C3","price":74.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d70c12256c804cf5e3a34b4b274a50d_c51032a5-6006-4dea-862b-9e7ce700b746.jpg?v=1788905769","url":"https:\/\/voomisupply.com\/products\/harvey-tool-826878-c3-square-end-mill-5-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
