Accupro 12184844 Ball End Mill 0.5 in 4 Flute Carbide

Product Description

The ACCUPRO 12184844 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers consistent edge integrity and extended tool life compared to high-speed steel alternatives. The ball-nose geometry produces contoured surfaces, 3D profiles, and radiused slots in a single pass. At 0.5 inches in diameter with a 40-degree helix angle and 4 flutes, this tool balances chip evacuation with surface finish quality. It is suited for use on CNC machining centers and manual knee mills where dimensional accuracy and tool rigidity are required.

This end mill is used in job shop, production, and tool-and-die environments for profiling, contouring, and semi-finish or finish milling passes. The stub-length configuration keeps the tool rigid and minimizes deflection, making it appropriate for shorter-reach applications in mold work, die cavities, and contoured part features. The single-end design and right-hand cutting direction are standard for conventional CNC setups. Machinists and CNC operators working in aerospace, automotive, and general manufacturing will find this tool fits standard collet and end mill holder tooling systems.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• Ball-nose geometry enables 3D contouring, profiling, and radiused slot milling
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• 4-flute configuration increases feed rate capability and improves surface finish
• Stub-length design reduces overhang and minimizes tool deflection
• Uncoated finish suitable for use with cutting fluids on a wide range of workpiece materials

Compatibility

Designed for use in standard 1/2 inch collets, end mill holders, and shrink-fit tooling systems on CNC machining centers and manual mills.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the holder to the recommended gauge line and torque the collet or set screws according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
