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)

Jacob Q. ★★★★★

The coating on this bit held up beautifully through a full run of hardwood, and the cut finish was glass-smooth with zero burning. It's definitely earned a permanent spot in my router table setup.

Kevin Q. ★★★★★

Picked this up for rounding over some walnut edges and the AstraHP coating really does keep it cutting cool — no burning like I got with my old uncoated bit. The 1/16" size is perfect for tight detail work on small boxes.

George ★★★★★

The full radius on this bit leaves an incredibly smooth floor in my aluminum pockets, way better than the flat end mills I was using. The AstraHP coating seems to be holding up well after a few hours of cutting.
