"Having drilled a 20mm dia hole through my house outer wall i enlarged it with this drill did the job fine at a quater the price of retailers. Also orderd on internet picked it up 2hrs later great service"
"I've sheared off many large sized SDS drill bits from the shank in the past. I always counterdrill the holes and build up the sizes to the largest to take the strain off the drill and bits. This bit cut through a brick no bother after been counterdrilled with a 18mm previously."
