What this tool is

The M.A. Ford 16512500A Tuffcut GP is a four-flute ball-nose stub end mill with a 1/8 inch cut diameter. It is intended for general-purpose profiling and contouring in a range of materials on CNC or manual milling machines. The stub length provides increased rigidity for shallow cuts and reduced deflection.

Installation and common issues

The shank mounts directly into a standard collet or end-mill holder matching the shank diameter; ensure the holder is clean and the tool is clamped to the correct depth. Common problems include chatter from excessive stick-out, premature wear if feed and speed are not matched to the workpiece material, and breakage if the tool is used for deep slotting beyond its stub length.

Deciding specification

The 1/8 inch cut diameter is the single dimension that determines whether this cutter fits the required feature size and machine capability. Buyers needing a larger or smaller radius, a longer reach, or a different flute count for chip evacuation in specific materials should select a different tool.

Questions about this item

How can I confirm the 1/8-inch Tuffcut GP end mill is cutting correctly after installation?

Check for smooth, chatter-free cuts and a clean ball-nose finish on the workpiece; the four-flute design should leave an even surface when feed and speed are set for the material.

What comes with the 16512500A end mill and what must I supply separately?

The box contains the single 1/8-inch stub-length ball-nose cutter; you must provide a compatible tool holder, collet or shrink-fit chuck and the cutting fluid or coolant suited to your application.

Which version of the M.A. Ford Tuffcut GP stub end mill should I choose for a 1/8-inch radius job?

Select the 16512500A model — it is the 1/8-inch diameter, four-flute ball-nose stub configuration designed for that radius.
