Accupro 12180951 Ball End Mill 0.0938 in 2 Flute Carbide

Product Description

The ACCUPRO 12180951 is a single-end ball end mill designed for precision milling of contoured surfaces, slots, and profiling operations in ferrous and non-ferrous metals. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding CNC machining applications. The cutting diameter is 0.0938 inches with a matching length of cut of 0.0938 inches, a 30-degree helix angle, and an AlTiN coating that improves heat resistance and tool life in dry or minimal-lubrication cuts. This tool is sold as a single end mill and is suited for machinists and tool-and-die professionals running high-speed milling operations.

This end mill is intended for CNC machining centers and manual mills where small-diameter ball nose geometry is required for 3D contouring, radius profiling, and finish milling in tight geometries. The 1/4-inch shank diameter makes it compatible with standard collet chucks and end mill holders commonly found on vertical machining centers. It is appropriate for both prototype shops and production environments handling steel, stainless, cast iron, and similar materials where the AlTiN coating provides thermal protection at elevated cutting speeds.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• AlTiN coating for extended tool life in high-heat, dry machining conditions
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Single-end design with a 4-inch overall length for reach in deeper setups
• 2-flute geometry suited for slotting and profiling in tighter workpiece features

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for CNC machining centers and manual mills equipped with 1/4-inch collet or end mill holder tooling.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Confirm the collet or tool holder is rated for the 1/4-inch shank diameter and that runout is within acceptable tolerance before beginning a cut. Avoid overtightening collet nuts, which can distort the shank and affect tool concentricity.
