Q-500: I'm trying to get some paint off a concrete block wall. I tried a 4" crimped brass wire wheel with 1/4" hex shank. That gets a lot of the paint off but not all of it. What do you recommend?
Our ITEM# 72788 crimped wire wheel should do the trick on a 4.5" grinder.
Q-502: What is the difference between ITEM #72747 and the Forney Command Pro 6 inch wheel?
Our ITEM# 72747 has a face dimension of 7/8" and the wire is .008" in diameter. This unit accommodates 1/2" and 5/8" arbors. The Forney Command Pro version of the wheel comes with a 5/8" or 1" face dimensions and the wire is .012" in diameter. The ITEM# will change based on the face dimension. The wire is half again as thick as the wire on the 72747 and will perform better and last longer. The Command Pro version has an arbor system that will accommodate 7 different arbor sizes between 1/2" and 2". The ITEM# for the 5/8" version of the Command Pro wheel is 72895 and the 1" version is 72896.
