Roscoe writes: “I’ve seen this advertised several places but admittedly haven’t tried one yet. It looks like a big time saver for installing Trex or other composite decking. The fixed depth feature would make for a very neat installation and makes me think you might even be able to use it with a long bit extension and drill the holes standing up.”
What say you? Do any of you have experience with these?
