M.A. Ford 16547240A 12.0mm 4-flute ball nose end mill stub

12.0mm 4-flute ball nose end mill

This M.A. Ford 16547240A end mill is a 12.0mm diameter cutting tool with four flutes and a ball nose profile. It is designed for machinists and fabricators who need to produce contoured surfaces, radii or full 3-D profiles in a variety of workpiece materials. The stub length provides increased rigidity for shallow cavity work where tool deflection must be minimised.

Replaces shorter-reach ball nose cutters

The stub length upgrades standard long-series ball nose tools when the application allows a shorter projection. The jump is worth it when the setup can accommodate the reduced reach because the shorter flute length and overall length lower vibration and improve surface finish on contoured features. It is not for deep-pocket or high-wall machining where the flute length cannot reach the full depth of cut.

12.0mm diameter with four flutes

The 12.0mm diameter and four-flute geometry comfortably handle medium-profile roughing and finishing passes on contoured surfaces where chip evacuation is manageable. The tool runs out when the required depth of cut exceeds the stub flute length or when slotting deep, narrow cavities that demand a longer reach and fewer flutes for chip clearance.
