Review on Shank Cutter Concrete Cement CBTONE by Christopher Isaac

Not a construction version, but good enough for smaller jobs. Unfortunately I will not be using this item. The hole has to be on the outside first, but my holes are already there and I'm renovating the bad masonry. The brickwork around the existing plastic stove pipe with an efficiency of 95% and the new air conditioning system is being carried out. The HVAC contractor drilled holes in the edge joists and simply knocked out the bricks until he found the holes in the edge joist and filled in the missing bricks with mortar.
