I was not sure where to post this. Under power carving or tools but tool seemed the best. My wife got me this for Christmas. I was not sure it would be something I would use alot. I was wrong. Great accessory for clean up and finishing. I am still using disc one. It will make short work of smoothing out those small dings or chisel marks that seem to take for ever to hand sand. Will not dig in at slow rpms were a burr can sometimes. I have the 150 grit disk its flexibility is a asset when working with curves. You just need a light touch. If you leave it in place to long the edge will leave marks. I thought is was worth sharing.
