SKU CH-K0GB-8C1WV

Four-flute ball-nose end mill for precision contour milling in a stub length

  • Four-flute ball nose cuts complex contours smoothly
  • 5 mm diameter suits precision milling tasks
  • Stub length increases rigidity for accurate finishing
  • TuffCut GP geometry extends tool life in general-purpose work
  • M.A. Ford quality ensures consistent performance in power tool applications

5.5 mm Ball Nose End Mill

The M.A. Ford 16521650 is a Tuffcut GP stub-length end mill with a 5.5 mm cutting diameter and four flutes. Its ball nose profile is intended for contouring, profiling and slotting operations where a radius finish is required. The tool is supplied new and falls under the Power & Pneumatic Accessories category for machining applications.

General-purpose milling in steel and cast iron

Machinists running CNC or manual mills on common ferrous materials will find the four-flute geometry suitable for a range of speeds and feeds. Workshops that need extended reach, specialised coatings for exotic alloys, or a different helix angle for non-ferrous metals should evaluate alternative tooling.

Stub length rigidity under sustained cuts

The short overall length reduces deflection during prolonged profiling passes, helping maintain dimensional accuracy when the cutter is engaged for longer periods. Heat buildup in the flutes remains manageable with standard flood or mist coolant, allowing consistent material removal without frequent tool changes.

Questions about this item

What shank diameter must my collet or tool holder accept for the 5.5 mm ball nose end mill?

The cutter has a 5.5 mm cutting diameter; match the holder to the shank size marked on the tool body.

Can I run this stub-length 4-flute mill in a standard ER collet chuck on my older CNC router?

Yes, provided the collet matches the shank and the machine can reach the required spindle speed for the material.

How do I verify the 16521650 is cutting correctly after installation?

Check for even chip formation, consistent sound, and the expected ball-nose radius on the finished contour.
