Precision Ball Nose End Mill

The M.A. Ford 156M0050N5A is a 0.50 mm diameter, two-flute ball nose end mill with a necked design. It is intended for machinists and engineers performing high-precision contouring, finishing or 3D profiling in a variety of materials. The small cutting diameter suits intricate detail work where standard tools cannot reach.

Stepping Up From Larger Roughing Tools

This cutter replaces larger-diameter roughing end mills when a finer finish or tighter corner radius is required. The jump is worth it when the workpiece features narrow channels, deep cavities or complex geometries that demand the .50 mm reach and necked clearance. It is not for high-volume material removal or heavy stock hogging where a bigger tool cuts faster.

Straightforward Collet Mounting

The plain shank fits standard ER collets or shrink-fit holders without special adapters. Runout must be minimised at the holder because the tiny diameter amplifies any eccentricity. Common issues include tool deflection in deep slots and premature wear if feed rates are not reduced for the small chip load.

Questions about this item

What shank diameter does the 0.50 mm ball nose end mill need for the tool holder?

The cutter has a 0.50 mm cutting diameter and a necked shank; match the holder bore to the shank diameter shown on the tool drawing.

Which step is most often missed when installing the necked 2 flute end mill in a collet?

Clean the shank and collet bore completely, then tighten the collet nut to the torque value for the holder size so the neck cannot pull out under cut forces.

When should the 156M0050N5A be replaced instead of re-sharpened?

Replace it once the ball nose radius wears beyond tolerance or the carbide shows chipping, because the 0.50 mm diameter leaves little material for re-grinding.
