M.A. Ford 20.0mm Ball Nose End Mill

The M.A. Ford 14078740 Tuffcut GP is a four-flute ball nose end mill with a 20.0mm cutting diameter. It is designed for general-purpose milling operations in a variety of materials. Machinists and fabricators use this tool for contouring, profiling, and pocketing applications where a radius bottom is required.

Four-flute geometry for sustained cutting

The four-flute design provides increased core strength and allows for higher feed rates during extended production runs. This geometry distributes cutting forces across multiple edges, reducing deflection and vibration when the tool is engaged for long periods. The ball nose profile maintains consistent contact geometry throughout deep cavity work.

Standard shank fits common tool holders

The cutter uses a standard shank configuration compatible with ER collets, Weldon flats, and shrink-fit holders found in most machine shops. Setup requires verifying the shank diameter matches the holder bore before tightening. The most common issue is insufficient clamping force or excessive stick-out, which leads to chatter and reduced tool life in harder materials.

Questions about this item

How much heat does the 20.0 mm Tuffcut GP end mill generate during extended cuts?

Heat depends on the workpiece material, cutting speed, feed rate and coolant strategy; the tool itself has no published thermal rating.

What machine and holder are required to run the 14078740 end mill?

A CNC mill or router with a spindle that accepts a 20.0 mm shank and a matching collet, hydraulic chuck or shrink-fit holder.

Will the 4-flute ball-nose cutter work with older tooling boards or fixture plates I already own?

Yes, it cuts standard ferrous and non-ferrous alloys; the ball-nose profile simply requires 3D tool-paths that your CAM software must support.
