Accupro 12184276 Ball End Mill 0.125 in 2 Flute Carbide

Product Description

The ACCUPRO 12184276 is a solid carbide ball end mill designed for precision milling of contoured surfaces, 3D profiles, and complex geometries in ferrous and non-ferrous materials. The 0.125-inch diameter cutting end is paired with a 0.75-inch length of cut and a 3-inch overall length, making it well suited for reaching into pockets and tight areas without excessive deflection. Micrograin carbide construction and a 40-degree helix angle contribute to smooth chip evacuation and edge stability. The AlTiN coating provides thermal resistance and extends tool life in demanding cutting conditions. This is a single-end, right-hand cut tool ground for consistent performance run to run.

This end mill is used in CNC machining centers and manual mills for finish and semi-finish passes on hardened steels, stainless steels, cast iron, and high-temperature alloys. The long-reach configuration suits mold and die work, aerospace components, and precision part production where standard-length tools cannot access the feature. Machinists and tool-and-die professionals working in job shops, production facilities, and maintenance machine shops are the primary users.

Key Features

• 0.125-inch ball nose diameter for tight-radius contour and profile milling
• Micrograin solid carbide substrate for rigidity and edge retention
• AlTiN coating for high heat resistance and extended tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• 2-flute geometry balances chip clearance with surface finish quality
• Single-end design with 0.125-inch straight shank for standard collet mounting

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 0.125-inch round shank via ER collet, end mill holder, or equivalent toolholding system.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked before inserting or removing the tool. Seat the shank to the full recommended collet engagement depth and torque the collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout at this diameter will rapidly degrade edge life and surface finish.
