M.A. Ford Tuffcut GP end mill

The M.A. Ford 16509840 Tuffcut GP is a four-flute ball nose end mill with a 2.5 mm cutting diameter. It is designed for general-purpose milling in a range of materials using CNC or manual machines. The stub length provides increased rigidity for shallow profiling and contouring work. This new accessory suits machinists and maintenance teams needing a reliable tool for finishing passes.

Thermals noise and power draw

As a solid carbide rotary cutter, this end mill generates heat only at the cutting interface during machining. Thermal load depends entirely on spindle speed, feed rate, workpiece material and coolant strategy employed by the operator. The tool itself has no motor, fan or electrical draw; noise levels are dictated by the machine spindle and cutting conditions. Proper speeds, feeds and lubrication manage heat and vibration effectively.

2.5 mm ball nose cutting diameter

The 2.5 mm ball nose radius defines the smallest internal corner radius and contour detail this tool can produce. It determines the stepover distance for 3D surfacing and the finish quality on curved surfaces. Buyers needing larger radii for faster material removal or smaller diameters for finer detail must select a different size. This specific diameter fixes the tool's geometric capability for profiling and finishing operations.

Questions about this item

How do I install the 2.5 mm Tuffcut GP end mill in a collet without damaging the shank?

Clean the shank and collet bore, insert the tool to the full gripping length, and tighten the collet nut to the holder manufacturer's torque spec so the 4-flute cutter runs true.

What maintenance will the 16509840 ball-nose cutter need during its service life?

Inspect the four cutting edges for chipping or wear after each job; resharpen on a proper grinder when the ball profile degrades, and replace the tool once the stub length becomes too short for safe clamping.

What limit appears first when the 2.5 mm stub end mill runs at high feed rates for a long cut?

The short stub length concentrates heat in the 4-flute carbide body, so thermal softening or edge chipping typically occurs before the shank or holder reaches its torque limit.
