What this end mill is

The M.A. Ford 16531250C Tuffcut GP is a four-flute ball-nose end mill with a stub-length design and a 5/16 inch shank. It is manufactured for general-purpose milling in a range of materials. The tool is supplied new and ships directly from the manufacturer.

How it fits in a milling setup

This cutter mounts in a standard tool holder or collet that accepts a 5/16 inch shank. The stub length keeps the cutting zone short, which adds rigidity and reduces deflection during profiling or pocketing. The four-flute geometry allows higher feed rates while still clearing chips effectively. Orders valued at $75 or more ship free from the manufacturer.

Who this suits and who should look elsewhere

Machinists needing a rigid, general-purpose ball-nose cutter for contouring or finishing operations will find this tool appropriate. Buyers who require a longer reach for deep cavities, a different shank diameter, or a specialised coating for high-temperature alloys should look at other options. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How quickly does the 4-flute ball nose geometry wear when cutting hardened steel all day?

The stub-length design and four-flute construction resist deflection, extending edge life during continuous profiling of tough alloys.

Does the carbide body run hot enough to need coolant after an hour in a CNC router?

Carbide dissipates heat efficiently; flood or mist coolant keeps temperatures stable during extended production runs.

What collet or holder size matches the 5/16 shank on this end mill?

A standard 5/16 inch ER collet or Weldon flat holder secures the shank without adapters.
