With a 15\/64-inch (0.2344-inch) cutting diameter and a 40-degree helix angle, it delivers aggressive chip evacuation and smooth cutting action across a range of materials. The 4-flute, spiral-flute geometry supports both slotting and peripheral milling. Centercutting capability allows direct plunging into workpiece material. This tool is built for machinists and tool-and-die professionals running CNC mills and manual knee mills in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 1\/4-inch collets or end-mill holders, making it compatible with most CNC machining centers and manual milling machines equipped with that shank size. The stub-length profile — 1\/2-inch length of cut with a 2-1\/2-inch overall length — reduces deflection in tight-tolerance applications. The micrograin carbide substrate supports higher surface speeds than standard carbide, and the uncoated finish makes it well-suited for non-ferrous metals and plastics where coating adhesion is not desired.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/64-inch (0.2344-inch) cutting diameter with tight tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e40-degree spiral helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003e4-flute, centercutting design supports plunge milling and slotting\u003c\/li\u003e\n\u003cli\u003eDouble-end configuration provides two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — standard orientation for conventional CNC setups\u003c\/li\u003e\n\u003cli\u003eStub length minimizes overhang and deflection in precision applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 1\/4-inch collets or end-mill holders on CNC machining centers and manual knee mills requiring a square-end, 4-flute solid carbide tool in the stub-length class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding procedures. Ensure the spindle is fully powered down and locked before loading or removing the tool. Verify collet condition and clean the taper and shank contact surfaces before clamping to the specified holding torque. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 15\/64 inch (0.2344 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: 4\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: 1\/4 inch (0.2500 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: 2-1\/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\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: 12185212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755659264306,"sku":"12185212","price":47.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec4d6d5f2813fac92e35eb9dbd82874e.jpg?v=1788957719","url":"https:\/\/voomisupply.com\/products\/accupro-12185212-square-end-mill-15-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
