Built from micrograin carbide, it offers a 15\/64 inch (0.2344 inch) cutting diameter with a 3\/8 inch length of cut and a 1\/4 inch shank diameter. The 4-flute spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 2 inches overall length, this is a stub-length tool suited for rigid setups where deflection control is a priority. It is centercutting, allowing direct plunge entry into the workpiece. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is used in general-purpose milling of ferrous and non-ferrous metals, plastics, and composite materials. Its stub-length geometry makes it a practical choice for short-reach pockets, slots, and profile cuts where rigidity is more important than reach depth. The uncoated finish is well suited for aluminum, brass, and softer steels where coating buildup is not a concern. Right-hand cut and right-hand flute orientation is standard for conventional CNC milling spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 40-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eStub-length configuration improves rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for use in standard CNC spindles\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for aluminum, brass, and softer workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit solid carbide square end mill for CNC machining centers and manual mills accepting a 1\/4 inch shank diameter collet or tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists using a collet chuck or end mill holder rated for the 1\/4 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout on the tool holder is within acceptable limits before engaging the cut, as excess runout accelerates wear on carbide tooling. Follow shop-standard feeds and speeds for the workpiece material and consult tooling documentation for recommended cutting parameters.\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\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 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\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\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: 12182787\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734779494706,"sku":"12182787","price":26.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bddb91932f09f6e8a337a9b771fcd132.jpg?v=1788766943","url":"https:\/\/voomisupply.com\/products\/accupro-12182787-square-end-mill-15-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
