M.A. Ford 20.0mm ball nose end mill
The M.A. Ford 14078740A is a solid-carbide rotary cutter with four flutes and a ball nose profile. It is intended for machinists and fabricators who need to produce contoured surfaces, radii or 3-D profiles in a range of workpiece materials. The Tuffcut GP designation indicates a general-purpose geometry suited to both roughing and finishing passes. This tool is not for operators who require a flat-end or corner-radius profile for square-shouldered pockets.
20.0mm cutting diameter
The single specification that determines fit is the 20.0mm cutting diameter, which must match the programmed tool path and the machine spindle capacity. A 4-flute configuration provides a balance of chip evacuation and surface finish for this diameter. Buyers whose tool holders or collets cannot accommodate a 20.0mm shank should select a different size.
Four-flute capacity for contouring
Four flutes allow higher feed rates than two-flute equivalents while still clearing chips in profiling operations. The ball nose geometry comfortably handles 3-D surfacing, fillets and full-radius slots in steel, cast iron and non-ferrous alloys. The tool reaches its limit in very deep cavities where flute length restricts reach or where a flat-bottom finish is required.

Questions about this item
How does the 20.0 mm diameter affect material removal in a milling machine?
The 20.0 mm cutting diameter removes a wide swath per pass, reducing cycle time on large contours and deep pockets when the spindle has enough torque.
What shank standard does the 14078740A use and what machine holders accept it?
The end mill uses a standard cylindrical shank matching its 20.0 mm diameter, so it fits ER collets, Weldon flats or shrink-fit holders sized for 20 mm tooling.
What clearance does the 20.0 mm ball nose need inside a workpiece cavity?
A 20.0 mm ball nose requires at least 20 mm of radial clearance and enough axial depth for the flute length to avoid holder interference.
