Review: Great - Great tool!
Review: Perfect - This is my favorite step bit for work. I usually only to drill through aluminum ductwork or really then aluminum air handler walls. The bit is the perfect size when I need to drill a hole big enough for my bore scope or psychrometers or small enough for my manometer probes. One bit with many different applications. It has held up for months now.
