What is a Ball Nose End Mill?

Ball nose end mills, also known as full radius end mills or ball mills, are cutting tools where the nose radius is equal to half of the diameter of the tool. This creates a constant single radius (or ball) at the tool end with no straight edge (sharp corners) in the profile. They are used for contour milling, shallow slotting, pocketing and contouring applications. Ball nose mills are ideal for 3D contouring because they are less prone to chipping and leave a nice rounded edge.

Tip: Use a Roughing end mill first to remove large areas of material then proceed with a ball nose end mill.

Customer Reviews (4.8 / 5 · 5 reviews)

Chloe ★★★★★

Bought this .062 ball end for finishing some aluminum pockets on my benchtop machine, and the Astra coating really does keep the chips from welding to the flutes. Ran it at 18k rpm and the surface finish came out glassy smooth.

Evelyn U. ★★★★★

The 3-flute geometry clears chips way better than the 2-flute bits I used to run, and the Astra coating is still holding up after a dozen jobs in aluminum. Chucked one in my 1/8" collet for a deep pocket and the .062" ball nose left a clean floor finish.

Sebastian ★★★★★

Grabbed a few of these for profiling 6061 on my desktop CNC and the finish is noticeably cleaner than the two-flute I was using. The Astra coating seems to be holding up well after a handful of jobs, no buildup on the flutes so far.
