M.A. Ford 16520310 end mill

The M.A. Ford 16520310 is a 4-flute ball nose stub end mill with a 13/64 cutting diameter. It is made for general-purpose milling in a variety of materials. The stub length provides added rigidity for shallow cuts. Machinists and maintenance teams use it for profiling and contouring work.

Sustained cutting performance

The four-flute design allows higher feed rates while maintaining a smooth finish during extended operations. Shorter flute length reduces deflection when the tool is engaged for longer periods. Heat distributes evenly across the cutting edges, helping the tool hold its geometry under continuous load. Chip evacuation remains steady in slotting and pocketing cycles.

Build quality and shank fit

Solid carbide construction resists wear and keeps cutting edges sharp through repeated use. The standard shank fits common ER collets and end mill holders without adapters. California Proposition 65 notices indicate the presence of chemicals linked to cancer and reproductive harm. Proper ventilation and personal protective equipment are recommended during machining.

Questions about this item

Will the 13/64 inch diameter 4-flute ball nose end mill generate excessive heat when running all day in steel?

The stub length and four-flute design reduce deflection, helping control heat during extended cuts in steel. Use appropriate coolant and feed rates for the material.

What tool holder or collet is required to secure the 13/64 inch shank of this M.A. Ford 16520310 end mill?

A standard 13/64 inch collet or end mill holder matching your machine spindle is needed to clamp the shank securely.

Can this 13/64 inch ball nose stub end mill be used on an older manual milling machine with R8 taper?

Yes, it fits any R8 collet or holder that accepts a 13/64 inch shank, provided the machine can reach suitable speeds for carbide tooling.
