Kutzall Ball Nose Burrs are designed with versatility in mind. You can use the flat sides to quickly round-over an edge, or, use the rounded nose to produce a fillet in a corner, hollow-out a concave area, or make radius-bottom grooves. Either way, a Kutzall Ball Nose Burr will handle the task with ease.
Kutzall Ball Nose Burrs are available in a variety of head dimensions, in either coarse or fine grit, depending on what and how much you need to cut. And, with 1/4" or 1/8" shaft diameters, they can be used in your preferred rotary tool.
