M.A. Ford Tuffcut GP end mill

The M.A. Ford 16537500A Tuffcut GP is a four-flute ball-nose end mill with a stub length and a 3/8 diameter. It is designed for general-purpose milling in a range of materials using pneumatic or power-tool setups. Machinists and fabricators use it for contouring and profiling operations where a ball profile is required. The tool is supplied new and ready for immediate workshop use.

Replacing worn or general-purpose cutters

This end mill replaces dull or lower-flute-count cutters when finish quality and tool life become limiting factors. The four-flute geometry increases feed-rate capability compared with two- or three-flute alternatives in suitable materials. The upgrade is worth it when cycle times need to drop without sacrificing surface finish on contoured surfaces. It does not suit applications that demand long-reach or extended-length tooling.

Sustained-load behaviour in milling

Under continuous cutting the stub length minimises deflection, helping maintain dimensional accuracy during prolonged passes. The four-flute design distributes chip load evenly, reducing per-tooth wear when feed rates are kept consistent. Heat buildup is managed through standard coolant or air-blast practices common in pneumatic accessory workflows. The tool contains a chemical identified under California Proposition 65 as a cancer and reproductive-harm hazard.

Questions about this item

What shank diameter does the 3/8-inch Tuffcut GP 16537500 end mill need to fit my tool holder?

The cutter has a 3/8-inch diameter; match your collet or holder to that shank size for a secure grip.

How do I install the 4-flute ball-nose end mill without damaging the cutting edges?

Clean the holder bore, insert the shank fully, tighten the collet evenly, and avoid side loads on the flutes during seating.

When should I replace the M.A. Ford 16537500A ball-nose end mill?

Replace the tool when the ball radius shows visible chipping or when flank wear degrades surface finish beyond your tolerance.
