These deburr bits are really great. I fabricate items that I’ve made in my blacksmith shop, sometimes with my welder. These little guts are great for removing welding slag in small places that can’t be reached with an angle grinder.

Better than expected, but don't use on anything other than wood.

These cut well, balanced well, sharp and are not wearing out too quickly. Better value than I expected. I would buy these again.

The media could not be loaded. This set of small burrs is so versatile. The many sizes and shapes make any carving possible if you can imagine it. I carved a small crude pillar for a crystal ball in my Halloween decorations for my home. I’ve since used them for many small projects. They really do come in handy. One of the best tool purchases I’ve made this year. Highly recommend.

I got this for my Thumb rotary carver for carving on the go! Unfortunately the shanks are just a bit undersized so the collet won’t close properly. They do work with a dremel. Would return them but not sure it’s worth the 55 mile drive to drop them off.

In my hobby of putting handles on knife blanks I need a tool that will remove a lot of wood and quickly. Not having a bandsaw these remove a lot of wood. I use the them with a Foredom rotary tool
