I am 74 years old and was afraid to remove the ugly 18" x 18" tiles in my bathroom. I bought a 3 inch drill bit for this hammer drill and got to work. 25 minutes later all the tiles were lifted. The right tool also makes heavy work easier. I've only used this drill in the hammer-only position, but if the drill and drill and thresh modes don't work, I'm still getting my money's worth. Now let's move on to my wife's bathroom.
