With a 3\/16-inch cutting diameter and four flutes arranged at a 40-degree helix angle, it delivers aggressive material removal while leaving a finished surface. The AlTiN coating increases surface hardness and heat resistance, making it suitable for dry or high-speed machining. At stub length with a 3\/8-inch length of cut and 2-inch overall length, it offers rigidity in tight-clearance applications. Machinists and toolroom operators use this end mill in CNC machining centers and manual mills for ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general metalworking applications in job shops, production machining, and toolroom environments. The chipbreaker geometry reduces cutting forces and helps break chips into manageable lengths during roughing passes, which lowers the risk of chip packing in deep slots or pockets. The single-end, right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations found in the majority of vertical machining centers. The stub-length profile limits overhang and improves rigidity when machining shallow features where reach is not a constraint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for stiffness and wear resistance compared to HSS tooling\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish provides high-temperature resistance for dry and high-speed cutting applications\u003c\/li\u003e\n  \u003cli\u003eChipbreaker geometry reduces cutting forces and controls chip length during roughing passes\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle balances aggressive material removal with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eStub length with 3\/8-inch length of cut maximizes rigidity in shallow-feature machining\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute, single-end configuration for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in standard ER collets, end mill holders, and Weldon-style set-screw holders accepting a 3\/16-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed with the machine spindle fully stopped and the control in a safe or e-stop state. Ensure the collet or tool holder bore is clean and free of chips before seating the shank to the full recommended engagement depth. Torque the collet nut or set screw according to the toolholder manufacturer specifications — do not over-tighten. Verify runout with a dial indicator before commencing a cut, as excessive runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 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: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach\u003c\/strong\u003e: Non-Extended Reach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 12184977\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728148267314,"sku":"12184977","price":36.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fbc53ad9915e365db3cf95aaadd05e42.jpg?v=1788688796","url":"https:\/\/voomisupply.com\/products\/accupro-12184977-3-16-inch-4-flute-carbide-square-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
