Review on Daredevil Piece Spade Drill: Unleash Bosch's Power and Precision by Justin Zilinskas

I am a retired contractor and years ago when I wanted to drill in joists I had two choices. Either with a drill or muscle through the joist with an old style spade bit. I discovered these Daredevil spade bits about 5 years ago. i was sold They're short enough to fit my drill bit and chisel between joists and they feed like a drill bit. I highly recommend them because they drill through wood very quickly and easily.
