12.0 mm ball-nose end mill

The M.A. Ford Tuffcut GP 14047240A is a four-flute ball-nose end mill with a 12.0 mm cutting diameter. It is designed for contouring, profiling and finishing operations in a variety of workpiece materials. The tool suits CNC machinists and job-shop operators who need reliable profiling performance.

Four-flute geometry for stable profiling

The four-flute design increases core strength and reduces deflection during deep or heavy cuts. It distributes chip load evenly across the flutes to improve surface finish on contoured surfaces. The ball-nose profile frees the programmer from corner-radius constraints on 3D toolpaths.

Replaces worn or lower-flute-count ball mills

When an existing ball-nose mill shows flank wear or chatter on finishing passes, this tool restores consistent surface quality. The step up is worthwhile when a two-flute tool cannot hold tolerance on complex contours or when longer tool life reduces change-over downtime.

Questions about this item

How quickly does the 12.0 mm ball nose wear when milling hardened steel at full depth?

The four-flute geometry distributes chip load across all cutting edges, slowing flank wear on the 12.0 mm radius during extended passes in hardened alloys.

Does the cutter run hot or vibrate loudly during day-long production runs?

Balanced flute spacing and the Tuffcut GP substrate keep vibration low, so spindle noise stays steady and heat builds slowly even in continuous operation.

What shank size and holder type does the 14047240 end mill need to mount securely?

The tool uses a standard 12.0 mm cylindrical shank that fits any ER collet, shrink-fit or hydraulic holder matching that diameter.
