M.A. Ford Tuffcut GP 4.0mm End Mill

This M.A. Ford 16515750A Tuffcut GP end mill is a 4.0mm stub-length cutter with a four-flute ball nose geometry. It is supplied new for machinists and maintenance teams who need a rigid tool for contouring, profiling and finishing operations in a variety of materials.

Four-flute ball nose stub construction

The four-flute design increases core strength and allows higher feed rates while the ball nose profile creates smooth radii in pockets and slots. Stub length reduces deflection during heavy cuts, and the standard shank fits common ER collets, Weldon holders and shrink-fit systems used in everyday CNC and manual milling setups.

4.0mm cutting diameter decides fit

The 4.0mm diameter determines whether this cutter matches the required corner radius, step-over allowance and tool-changer capacity for a specific job. Shops needing a larger or smaller radius, a longer reach, or a different flute count must select an alternative tool because this model is fixed at 4.0mm.

Questions about this item

What shank diameter does the 4.0 mm Tuffcut GP end mill use?

The cutter has a 4.0 mm diameter, which matches the shank size required by standard ER collets or Weldon holders for stub-length tools.

What holder clearance does the stub-length ball nose need?

Its reduced overall length fits tight spindle-to-workpiece gaps on CNC routers and milling machines without hitting fixtures or the machine table.

How is the 4-flute ball nose secured in a collet chuck?

Insert the shank fully into the ER collet, tighten the nut to the maker's torque spec, and verify run-out before cutting — partial insertion causes vibration and premature wear.
