Manufactured from micrograin solid carbide, it offers rigidity and wear resistance across a range of machining applications. The tool features a 0.25 inch mill diameter, a 1.5 inch length of cut, and a 4 inch overall length, placing it in the extra-long category for reaching deeper cavities and pockets. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is uncoated and ready for use in applications where coating is not required or where regrinding is anticipated.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for CNC machining centers and manual mills performing contour milling, profiling, slotting, and 3D surface work. The ball nose geometry makes it appropriate for finishing passes on curved surfaces and complex part geometries. The extra-long overall length allows access to deep features that standard-length tools cannot reach. It is installed and operated by machinists, tool-and-die makers, and CNC programmers working in job shop, aerospace, mold-and-die, and general manufacturing environments.\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\u003e0.25 inch mill diameter with mill diameter tolerance of +0.000 to -0.002 inches\u003c\/li\u003e\n\u003cli\u003e1.5 inch length of cut and 4 inch overall length for extended reach into deep pockets\u003c\/li\u003e\n\u003cli\u003e40-degree right-hand spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSingle-end ball nose geometry suited for contouring and 3D surface finishing\u003c\/li\u003e\n\u003cli\u003eUncoated finish — compatible with regrinding services\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-install tool for standard 0.25 inch collet or end mill holders on CNC machining centers and manual knee mills accepting right-hand cutting tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder that matches the 0.25 inch shank diameter; verify shank seating depth per machine tool specifications. Confirm cutting direction is set to right-hand before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -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\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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: 12184247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750170689842,"sku":"12184247","price":57.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40d6a16a6597a3864d24414838b65459.jpg?v=1788914030","url":"https:\/\/voomisupply.com\/products\/accupro-12184247-ball-end-mill-0-25in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
