Man, they have something for everything don't they.Sounds like them old school sharpeners in the classroom on a quiet test day.This will be my next cordless drill upgrade.If anyone has ever had the displeasure of running a stump grinder, this attachment is a God send.He needs a giant to lean in and blow the woodchips away, so he can see what he's doing.I wished we would have had something like that when I was young I spent way too many hours and days digging out or burning out stumps.
