With a 3\/64 inch (0.0469 inch) cutting diameter and a 9\/64 inch (0.1406 inch) length of cut, this tool is built for small-feature work including slots, pockets, and profiling cuts on hardened or abrasive materials. The micrograin carbide substrate provides rigidity and wear resistance, while the TiCN coating reduces friction and extends tool life in ferrous and non-ferrous materials. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces on the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where fine detail work is required. It is commonly used in mold and die work, precision component manufacturing, and prototype machining where small diameters and accurate wall geometry are critical. The 1\/8 inch shank diameter fits standard collets and toolholders used on most benchtop and full-size milling machines. Its 1-1\/2 inch overall length keeps deflection to a minimum when working in shallow features.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention in demanding materials\u003c\/li\u003e\n  \u003cli\u003eTiCN (Titanium Carbonitride) coating reduces friction and improves wear resistance\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design with 30-degree helix angle for efficient chip evacuation in small slots and pockets\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC and manual mill setups\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0002\/-0.0008 inch for tight-tolerance feature work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/8 inch collets and toolholders on CNC machining centers and manual milling machines.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before mounting the end mill. Secure the shank fully within the collet to the recommended engagement depth to minimize runout and prevent tool pull-out during cutting. At this diameter, even slight runout can significantly reduce tool life and cut quality, so verify collet condition and concentricity before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/64 inch (0.0469 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/64 inch (0.1406 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: 1-1\/2 inches (1.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002\/-0.0008 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728187949362,"sku":"12181228","price":26.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d00cabd8746b2f1c394ee204df9cc98.jpg?v=1788689214","url":"https:\/\/voomisupply.com\/products\/accupro-12181228-square-end-mill-3-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
