Accupro 12184121 Ball End Mill 0.2344 in 2 Flute Carbide

Product Description

The ACCUPRO 12184121 is a solid carbide ball end mill designed for precision milling of contoured surfaces, 3D profiles, and slotting operations in metalworking and machining environments. Measuring 0.2344 inches in diameter with a 0.375 inches length of cut, this stub-length tool provides added rigidity during light to medium-duty milling. The 40-degree helix angle promotes efficient chip evacuation while reducing cutting forces. With two flutes and a right-hand cutting direction, it is suited for conventional and climb milling on CNC mills and manual knee mills. Machinists and tool-and-die professionals are the primary users of this tool.

This end mill is built for close-tolerance finish work on ferrous and non-ferrous metals where a small-diameter ball profile is required. The stub length format reduces deflection, making it appropriate for shallow pockets, blending passes, and contour work on mold components, fixtures, and precision parts. The uncoated micrograin carbide construction allows for use with or without cutting fluid and is compatible with regrinding services to extend tool life.

Key Features

• 0.2344 inches (15/64 inch) mill diameter with a tight tolerance of +0.000 to -0.002 inches
• Solid micrograin carbide construction for hardness and wear resistance
• 40-degree right-hand helix for efficient chip evacuation and smooth cutting action
• Stub length format increases rigidity and reduces deflection in tight setups
• Uncoated finish compatible with regrinding and suitable for a wide range of workpiece materials
• Single-end ball nose geometry for 3D contouring, profiling, and blending operations

Compatibility

Designed as a standard single-end ball nose end mill for use in CNC machining centers and manual mills accepting a 1/4 inch round shank. Confirm spindle collet or tool holder compatibility before installation.

Installation Notes

Installation requires a collet or end mill holder sized for a 1/4 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank to the full recommended engagement depth in the holder to minimize runout and tool pullout risk. Verify shank diameter tolerance compatibility with the holder; the shank tolerance on this tool is -0.0001 to -0.0004 inches.
