  • M.A. Ford quality ensures reliable performance in tough materials
  • TuffCut GP series built for general-purpose machining versatility

Tuffcut GP 4-flute ball-nose end mill 7/16

This M.A. Ford solid-carbide end mill carries the Tuffcut GP designation and features four flutes with a ball-nose profile in a 7/16-inch diameter. The stub-length flute reduces overhang for greater rigidity in general-purpose milling of steel, stainless steel, cast iron and non-ferrous alloys. It suits CNC operators and job-shop machinists who need a versatile finishing tool for contouring, profiling and pocketing operations.

Check toolholder and machine compatibility

Verify that your collet, hydraulic chuck or shrink-fit holder accepts a 7/16-inch shank and provides sufficient clamping length for the stub flute. Confirm the spindle can deliver the speed and feed rates recommended for the material being cut without exceeding the toolholder’s run-out tolerance. Ensure coolant delivery — flood or through-spindle — reaches the cutting zone for chip evacuation and temperature control.

Replaces worn or lower-flute-count ball-nose tools

Swapping a dull two- or three-flute ball-nose mill for this four-flute stub version increases feed capability and improves surface finish on contoured surfaces. The upgrade is worthwhile when cycle-time reduction and tighter tolerances on 3-D profiles outweigh the higher tool cost. It does not suit applications requiring extended reach, deep-pocket clearance or high-helix geometries for difficult-to-machine materials.

Questions about this item

What is included with the M.A. Ford 16543750 end mill and what must be purchased separately?

The package contains the Tuffcut GP 4-flute ball-nose end mill itself; a tool holder or collet to secure the 7/16 shank in your milling machine is sold separately.

How do I choose between the available versions of the Tuffcut GP 4-flute ball-nose end mill?

This listing is for the stub-length 7/16 diameter version only; other lengths or diameters would appear as separate product numbers.

What does the 4-flute ball-nose geometry mean for actual milling performance?

Four flutes provide a finer finish and higher feed rates in finishing passes, while the ball-nose profile allows 3-D contouring and radius-bottom slots in a single tool.
