Needed to drill through cavity wall (breeze block and brick) for bathroom vent. Bought this with the extra extension piece and cut through the wall fairly easily. The only problem I found was the bolt which attached the guide drill to the cutting tool shook itself loose and got lost in the cavity even though it was properly tightened. I would suggest checking it regularly whilst cutting. Worth it for the price.
