Review on Ultimate Precision: Double Cut Carbide Rotary Burr for Finest Material Shaping by Ricky Habbani

Couldn't remove the factory rivets from the truck frame to replace the cross member due to their location. I cut off the heads with a standard grinder/cutting wheel, then bought them and used a dremel to carve them. I totally wore some of them down, but was able to get work done that I had no other reasonable way to get done. As a disposable tool, they worked well and didn't cost unreasonable money.
