Accupro 12184179 Ball End Mill 0.433 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12184179 is a solid carbide ball end mill designed for precision milling operations in ferrous and hard materials. It measures 0.433 inches (11 mm) in diameter with a 0.5512-inch (14 mm) length of cut and a 40-degree helix angle. The cutting geometry uses two right-hand spiral flutes with a micrograin carbide substrate, providing rigidity and edge retention in demanding applications. An AlTiN coating improves heat resistance and extends tool life in high-speed and dry machining environments. This is a single-end, stub-length tool with a 12 mm shank diameter and a 76 mm overall length.

This ball end mill is suited for contour milling, profiling, and 3D surfacing operations on CNC machining centers. The stub-length configuration reduces deflection and improves rigidity in shorter reach applications. The AlTiN coating makes it particularly effective in hardened steels, stainless steels, and high-temperature alloys where heat buildup is a concern. It is typically installed and used by machinists and tool-and-die professionals in both production and job-shop environments.

Key Features

• 0.433-inch (11 mm) ball nose diameter for contour and 3D profiling work
• AlTiN coating for high-heat resistance and extended tool life in hard materials
• Micrograin solid carbide substrate for edge sharpness and wear resistance
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Stub-length design minimizes deflection in short-reach milling applications
• Single-end, right-hand cut and right-hand flute spiral configuration

Compatibility

Designed as a standard shank ball end mill compatible with CNC machining centers and manual mills accepting a 12 mm round shank via collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before loading or changing tooling. Seat the 12 mm shank to the full recommended grip depth in the collet or holder to prevent pullout under cutting load. Verify runout with a dial indicator before beginning a cut, particularly for finish profiling operations.
