The tiles in 2 bathrooms have to be removed, Click&Lock tiles have been laid on the floor. This hole punch is the right tool to get the job done faster. It went through the entire tile and cement base like butter. This $20 add-on purchase from AMZ helped a lot: S&R tile bit, MADE IN GERMANY, 165 x 75mm (6.5" x 3"), SDS-Plus - optimized geometry and curved shape. Vendor: Werkfix It's always an advantage to have the right tool for the job and for tile + cement + wire mesh backing this worked great. Front porch remodeling nearby. Decaying mortar and brick.
