Drill brushes are most effective when used to buff carved woodwork. It is a much more effective way of buffing a carved relief surface when compared to just using a cotton cloth. It will also help to remove any excess areas of wax polish caught in the carvings and recesses. It will also save you a lot of time. I would expect a drill buffed coffer would save about a quarter of the time when compared to hand buffing. Do not use a wax drill brush on smooth, flat horizontal surfaces such as dining tables, side tables, chests etc. It will more than likely result in striping of the wax on the surface, leaving an uneven finish. You can use it to buff table frames and chairs but I would always advise that you finish off the buffing with a cotton cloth.
