Review on Bosch BL9IM Black Impact Piece by Maxwell Thomas

Purchased for use with a Porter Cable Impact Wrench (also from Revain). I've tried out beats from Harbor Freight and Walmart and swept up a lot of broken beats. I've put these bits through the same duties with no problem - and they went through ⅛ inch steel strapping like cheese. Hard cheese, but cheese. Part of the durability may be due to the short length - the smaller bits in this set are about half the length of comparable bits in cheaper OTTO sets, they all look long enough for any purpose.
