With a 3\/8 inch cutting diameter and a 7\/8 inch length of cut, this end mill delivers consistent material removal in ferrous and non-ferrous applications. The micrograin carbide substrate provides the rigidity and edge retention needed for demanding cuts. An AlTiN coating enhances heat resistance and wear life, making this tool well suited to higher-speed dry or semi-dry machining. It is installed and operated by machinists and CNC programmers working with milling machines and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling applications requiring a 3\/8 inch shank and a regular-length tool profile. The 2-flute configuration supports efficient chip evacuation in slotting and peripheral milling operations. A 40-degree helix angle improves cutting action and surface finish on a range of workpiece materials. The right-hand cut and right-hand flute orientation is the conventional setup for the majority of vertical and horizontal milling machines. Centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth cutting action and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral geometry aids chip clearance in slotting and profiling cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard milling machine spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for standard milling machine and machining center toolholders accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup personnel. Secure the shank fully into the toolholder collet or end mill holder, ensuring the shank is seated to the recommended engagement depth before tightening. Verify spindle rotation direction matches the right-hand cut orientation of this tool before starting the machine. Inspect the cutting edges and coating condition prior to each use and replace the tool if chipping or excessive wear is present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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: +0.000 \/ -0.002 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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733197685042,"sku":"12181422","price":62.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f17df65b8e389002cd85f1c87acfb2a.jpg?v=1788752668","url":"https:\/\/voomisupply.com\/products\/accupro-12181422-square-end-mill-3-8-in-2-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
