It features a 17\/64-inch (0.2656-inch) cutting diameter, a 1\/2-inch length of cut, and a 5\/16-inch shank diameter, with a 2-inch overall length. The two-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, this stub-length end mill delivers rigidity and wear resistance suited to demanding machining environments. It is centercutting-capable, allowing plunge entry, and runs with a right-hand cut and right-hand flute configuration.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual milling machines across job shop, toolroom, and production environments. The stub-length design minimizes deflection during close-tolerance work in ferrous and non-ferrous materials. Its uncoated micrograin carbide construction makes it a practical choice for shops that regrind tooling. Machinists and toolroom operators working in general-purpose milling, slotting, and peripheral cutting applications will find the 17\/64-inch diameter useful for tight-tolerance feature work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e17\/64-inch (0.2656-inch) cutting diameter with a tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flute geometry for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eStub-length (2-inch OAL) body reduces deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard orientation for conventional milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose square end mill compatible with standard 5\/16-inch collets and end mill holders on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or end mill holder rated for a 5\/16-inch shank diameter and torque the retention mechanism according to the tool holder manufacturer specifications. Inspect the collet and holder for wear or contamination before seating the tool to ensure runout remains within acceptable limits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 17\/64 inch (0.2656 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\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\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 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\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\u003eLength Type\u003c\/strong\u003e: Stub\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: 12181632\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744561594674,"sku":"12181632","price":37.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee89f21b84d01df8070138a1bf214c9d.jpg?v=1788858195","url":"https:\/\/voomisupply.com\/products\/accupro-12181632-square-end-mill-17-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
