It features a 23\/64-inch (0.3594 inch) cutting diameter with a 5\/8-inch length of cut and a 3\/8-inch shank diameter, giving it a compact stub-length profile suited for rigidity in tight setups. The 2-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is an uncoated, centercutting tool, meaning it can plunge directly into the workpiece. It is installed and used by machinists and CNC operators in job shop, toolroom, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and plunging operations on ferrous and non-ferrous materials where a tight-tolerance, stub-length tool is required. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining centers and manual mills. The micrograin carbide substrate supports higher speeds and feeds compared to standard carbide grades, making it a solid choice for finish passes and light roughing on harder materials. The overall length of 2 inches and stub-length designation keep deflection low in applications where reach is not the primary concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e23\/64-inch cutting diameter with a mill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard orientation for most CNC and manual mills\u003c\/li\u003e\n\u003cli\u003eStub length (2-inch OAL) minimizes deflection and maximizes rigidity in short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use square end mill for CNC machining centers and manual vertical mills accepting a 3\/8-inch straight shank tool holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a compatible collet chuck, end mill holder, or set-screw holder sized for a 3\/8-inch shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the minimum insertion depth recommended for the holder type to maintain runout within tolerance. Verify shank diameter tolerance (-0.0001 \/ -0.0004 inches) is compatible with the holder before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 23\/64 inch (0.3594 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: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eCoating\u003c\/strong\u003e: Uncoated\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: 12181656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731950993714,"sku":"12181656","price":40.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bd8bfcbcbe438941ed7033c16cbd847.jpg?v=1788737129","url":"https:\/\/voomisupply.com\/products\/accupro-12181656-square-end-mill-23-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
