Accupro 12184499 Ball End Mill 0.25in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12184499 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hard material applications. The ball nose geometry allows for contoured surface milling, 3D profiling, and slotting in a single tool. Built from micrograin solid carbide, it delivers rigidity and edge retention in demanding cuts. With a 0.25 inch diameter, 1 inch length of cut, and a 40-degree right-hand helix, this end mill is suited for high-speed finishing and semi-finishing passes where accuracy and surface finish are critical. It is sold as a single-end tool with an uncoated finish.

This end mill is used in CNC machining centers, vertical mills, and manual milling setups for profiling, contouring, and pocket milling. The long flute geometry with a 1 inch length of cut and 4 inch overall length provides extended reach for deeper pockets and cavities without requiring a longer shank extension. It is a common choice for tool and die, mold making, aerospace component work, and precision job shop applications where micrograin carbide is preferred for its hardness and wear resistance.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• Ball nose geometry enables 3D contouring, profiling, and radius floor finishing
• 40-degree right-hand helix promotes chip evacuation and reduces cutting forces
• 3-flute design balances chip clearance with rigidity for finishing passes
• Long length configuration with 4 inch OAL for extended reach applications
• Uncoated finish suitable for dry cutting or use with cutting fluid on a wide range of materials

Compatibility

Designed as a standard shank ball end mill compatible with any CNC or manual milling machine spindle or collet system accepting a 0.25 inch round shank.

Installation Notes

Installation is performed by a machinist or CNC operator using a collet, end mill holder, or shrink-fit toolholder rated for the 0.25 inch shank diameter. Ensure the spindle and toolholder are clean and free of chips before seating the end mill. Always confirm runout with a dial indicator after clamping, as excessive runout accelerates edge wear on carbide tools. Follow machine manufacturer guidelines for maximum RPM and feed rates appropriate to the workpiece material.
