Accupro 12184096 Ball End Mill 5/32 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 12184096 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles. The ball nose geometry produces smooth, accurate radii on ferrous and non-ferrous workpieces. At 5/32 inch (0.1563 inch) diameter with a 3/8 inch length of cut and a 40-degree right-hand helix, this tool balances chip evacuation with cutting efficiency in demanding applications. The AlTiN coating adds heat resistance and hardness, extending tool life when cutting alloy steels, stainless, and hardened materials at elevated speeds. Machinists and tool-and-die professionals running CNC machining centers and mills are the primary users of this end mill.

This end mill is suited for finish and semi-finish milling of dies, molds, and precision components where a consistent ball radius is required. The stub length designation keeps deflection low in tight-clearance setups. The 3/16 inch shank diameter allows use in standard collet chucks and end mill holders. Applications include contouring hardened steel, titanium alloys, and other high-temperature alloys where AlTiN coating performance is critical to tool longevity and surface finish quality.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides thermal barrier and hardness for high-speed cutting of ferrous alloys
• 40-degree right-hand helix promotes efficient chip evacuation and smooth cutting action
• 2-flute ball nose geometry optimized for 3D contouring and radius profiling
• Stub length (3/8 inch LOC, 2 inch OAL) minimizes deflection in close-tolerance setups
• Single-end design with right-hand cutting direction for standard CNC spindle use

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in CNC machining centers and manual mills accepting a 3/16 inch shank via standard collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists following standard tool-change procedures. Always power down and lock out the machine spindle before seating or removing the tool from the holder. Ensure the collet or holder bore is clean and free of debris before clamping to achieve proper runout. Verify tool projection and reach before beginning a cutting program to avoid interference with fixtures or workholding components.
