Review on 🛠️ Irwin Tools 3043006 WeldTec Auger: Unleash Superior Precision and Performance by Donnie King

I have been using this drill for about six months while building a retaining wall for a garden beautification project. and use this drill to make pilot holes for the rebar spikes. Diameter 9/16 is the ideal hole size for rebar. It's long enough for me to drill 3 logs. I haven't used it to go through metal (nails or anything). After hundreds of holes it still works like new.
