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.

Leo B. ★★★★★

The AstraHP coating really cuts down on the burning I used to get on cherry, and the 1" cut depth let me hog out this deep cove in two passes. Finish off the tool is glassy smooth too, no sanding needed.

Aurora ★★★★★

The full radius on this leaves such a clean profile on my rounded edges. Coating seems to be holding up fine after a few sessions in hardwood. Way better finish than the straight bits I was using before.

Zoe U. ★★★★★

Picked up the 1" cut version for rounding over some walnut edges and the full radius leaves zero chatter marks. The coating seems to hold up well too, still cutting clean after a few hours of use.
