For the price of this item I expect pretty much perfection - it's three times more expensive than 'regular' chisels, but the drill boasts a square chisel. So instead of a straight side cut I have a jagged edge which then takes a lot of awkward chiseling to get it straight. At this point, I might as well have cut them by hand. LV's Japanese gouges are much better (but of course they were out of stock). Disappointed to have been a very good beat brand in the past.
