    • Works great
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.

    • Very useful
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

    • Cutting Bites
These bites were what I was looking for to use in trimming plastic parts. They will do other types of trimming and cutting.

    • Works well, nice variety of shapes
These cut well, balanced well, sharp and are not wearing out too quickly. Better value than I expected. I would buy these again.

    • Shank undersized.
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.

    • Nice bits. Exactly what I needed.
The selection of bit shapes is very handy. Caution, the are aggressive and shape wood easily.
