It features a 9\/64-inch (0.1406-inch) cutting diameter and a 3\/8-inch length of cut, with a stub-length profile that reduces deflection and improves rigidity in tight-reach setups. The 2-flute spiral geometry with a 40-degree helix angle promotes efficient chip evacuation, while the AlTiN coating extends tool life at elevated cutting temperatures. This end mill is centercutting, allowing direct plunge entry into the workpiece. Machinists and CNC operators in metalworking and precision fabrication shops are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous metals, hardened steels, stainless alloys, and similar materials where a tight-tolerance, high-performance carbide tool is required. Its stub-length design makes it appropriate for shallow pocket milling, slotting, and profiling operations where maximum rigidity is preferred over extended reach. The 3\/16-inch shank diameter fits standard ER-series collets and milling chucks compatible with that shank size. It is used in both production and job-shop environments on vertical and horizontal CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for heat resistance and extended tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eStub length profile minimizes deflection in shallow-depth milling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill compatible with any CNC milling setup accepting a 3\/16-inch shank diameter via ER collet, shrink-fit, or milling chuck toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool path is programmed before seating the end mill in the toolholder. Verify collet or chuck runout is within acceptable tolerance for the shank diameter, as runout directly affects tool life and surface finish. Follow shop-standard speeds and feeds for solid carbide tooling with AlTiN coating when establishing cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/64 inch (0.1406 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\/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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181595\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747404087602,"sku":"12181595","price":42.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9f9f8c88c43b795a95b1f7daf983ceb.jpg?v=1788879570","url":"https:\/\/voomisupply.com\/products\/accupro-12181595-square-end-mill-9-64-in-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
