M.A. Ford Tuffcut GP 4 Flute Ball Nose End Mill

The M.A. Ford Tuffcut GP 16537500C is a 4 flute ball nose end mill with a stub length designed for general purpose milling. It suits machinists and fabricators who need a rigid, short-reach cutter for contouring and profiling in a variety of materials. The 3/8 inch shank fits standard collets and holders used in CNC and manual milling setups.

Installation and Common Issues

The tool installs by securing the 3/8 inch shank in a compatible collet or end mill holder with appropriate run-out tolerance. Common issues include premature wear if feed and speed rates are not matched to the workpiece material, and vibration or chatter if the tool holder or machine spindle lacks rigidity for the stub length design.

Pre-Order Compatibility Checks

Verify that your machine spindle and tool holder accept a 3/8 inch shank and can accommodate the stub overall length without interference. Confirm the workpiece material and your machine capabilities suit a general purpose 4 flute geometry. Note the California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.

Questions about this item

How can I confirm the 16537500C Tuffcut GP end mill is cutting correctly after installing it in my pneumatic tool?

The 4-flute ball nose should produce a smooth, rounded bottom cut without chatter; listen for steady motor sound and inspect the workpiece for a consistent finish.

What comes with the 16537500C Tuffcut GP end mill and what must I supply separately?

The package contains the 3/8-inch stub-length carbide end mill only; you must provide a compatible pneumatic holder or collet and the air tool itself.

Which Tuffcut GP version should I choose for a stub-length 3/8-inch ball-nose application?

Select the 16537500C model — it is the 4-flute ball nose stub in 3/8 inch diameter, matching that exact specification.
