Pulled 20,000 pounds (3,000 square feet) of Saltillo tile in six days without a hitch. I've changed the beats a few times. All the work could have been done with two nozzles (2" tile nozzles). Incredible car. (Keep the nozzles cool between sanding by soaking them in cold water! Otherwise you'll kill the irritation on the nozzle and they'll go fast blunt!) Then I had to reshape three disgusting Kiva chimneys after sawing. With the help of a sharp bit and a small 1" chisel the job was easy. The four vents on the foam roof I then had to replace with larger ones. The 6". "Mortar chisel slid over the galvanized surface without damaging it and scraped the foam effortlessly. The chisel easily split the bottom plate and ripped it off the slab. Hard work just got a lot easier with this machine. I then had to between the Drilling notches in the sink on the living room floor and on the shower floor where I had to move the drain cake It took several minutes THEN my wife did the well-behaved rug nails pulled out the strips with a hammer and chisel, saw how easy Bosch did it, now SHE uses it to remove all the strips of nails. Initially suspicious of the $700 tool, she has repeatedly said how absolutely essential this thing is on this remodeling job. We've even used it to remove baseboards! This Bosch is a very precise destroyer. It puts a massive amount of energy into a small area and allows you to control that energy to your advantage. As it has paid for itself multiple times, we will keep it after completion because it makes digging plant holes so much easier here in Rocky Phoenix! I have even more patio tiles to clean up in the future. Really great tool. Indispensable! One note: mind your bits! To keep the bits in the hammer chuck from wearing out, apply a small amount of the supplied lubricant to the bit shafts. Remove them each time you remove one and only use a pea-sized amount on the next piece you use. This keeps the cartridge in top shape and the bits run quietly and cool. I would give this thing ten stars if I could.
