What this end mill does

The M.A. Ford 16515750 Tuffcut GP is a 4-flute ball nose end mill with a 4.0 mm cutting diameter. It is designed for general-purpose milling in a stub length configuration. Machinists use it for profiling, slotting and contouring operations on CNC or manual machines.

Check your toolholder and spindle

Verify that your collet or chuck accepts a 4.0 mm shank and that the stub length clears your fixture. Confirm the machine spindle can run at the speeds recommended for the material you are cutting. Ensure coolant or air blast is available if your application generates heat.

Behaviour in extended cuts

The stub length increases rigidity so deflection stays low during long passes. Four flutes distribute chip load evenly, reducing vibration when the tool stays engaged for several minutes. Heat builds gradually; consistent chip evacuation prevents re-cutting and protects the cutting edges.

Questions about this item

Does the 16515750 end mill come with a tool holder or just the cutter?

The listing covers the 4 mm ball-nose cutter only; a compatible collet or tool holder must be purchased separately.

Is the 4.0 mm stub length the only size offered in this Tuffcut GP series?

This MPN is the 4.0 mm stub version; other diameters and lengths carry different part numbers.

What does the 4.0 mm diameter mean for the cut profile in my CNC router?

A 4.0 mm ball-nose tool produces a 2 mm corner radius and four engaged flutes for finishing passes.
