What this tool is

The M.A. Ford 156M0400N16A is a 2-flute ball nose end mill with a necked design. It is intended for machinists and CNC operators who need a 4.0 mm cutter for contouring and profiling work in a variety of materials.

Deciding specification

The critical detail is the 4.0 mm cutting diameter combined with the necked geometry. That combination determines whether the tool can reach the features in your specific part without interference from the shank or holder.

What the bundle changes

No accessories or software are included with this cutting tool. Buyers who need tool holders, collets or coolant systems must source those separately. The product carries a California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.

Questions about this item

What does the 4.0 mm diameter mean when the cutter is in the spindle?

The 4.0 mm diameter is the cutting width of the ball nose, so each pass removes a 4.0 mm wide channel in the workpiece.

How does the necked design affect reach in a standard holder?

The necked shank provides extra clearance behind the flutes, allowing deeper pockets without the holder rubbing the workpiece.

What shank size fits a 4.0 mm necked end mill in a standard collet?

A 4.0 mm shank fits directly into a 4.0 mm collet or an ER collet sized for 4.0 mm.
