Its my favorite tool. I have an HF straight and bought a CP 90 degree after the HF 90 died. I run the 4000 rpm wire brushes all the time, just wear good eye protection and something more than a t-shirt. Get some 3" cutoff wheels and put your hacksaw away forever. I also run the 2" and 3" rolocs for removing paint and cleaning surfaces for gaskets. Indispensible tools.
