End Mill for General Machining

The M.A. Ford Tuffcut GP 16555120 is a 14.0 mm diameter ball nose end mill with four flutes and a stub length. It is designed for general-purpose milling in a range of materials where a rounded profile is required. The tool suits CNC operators and machinists producing contoured surfaces or finishing passes.

Limits of the Stub Length Design

The stub length increases rigidity and reduces deflection during cutting, but it restricts the maximum reach into deep cavities or tall features. Users must ensure the workpiece and fixturing allow sufficient tool clearance for the intended depth of cut. This geometry is not suited for deep-pocket milling or applications requiring extended reach.

Upgrade from Two-Flute or Longer Tools

This cutter replaces two-flute ball nose mills when higher feed rates and improved surface finish are priorities on compatible machines. It also supersedes longer-flute tools where vibration or chatter limits performance in shallow profiles. The jump is worthwhile when rigidity and material removal rate matter more than reach.

Questions about this item

Should I pick the 14.0 mm stub version or look for a longer flute length?

Choose the 14.0 mm stub length when rigidity matters most — shorter flutes deflect less in deep pockets or hard materials.

How does the four-flute ball nose geometry perform in a CNC router?

Four flutes give a finer finish and higher feed rates than two-flute tools, while the ball nose creates smooth 3-D contours in a single pass.

What shank standard does the 16555120 use and what does that limit?

The tool follows common imperial shank sizing, so it fits standard ER collets and shrink-fit holders but will not suit metric-only tooling systems.
