Rated 4.0 out of 5 by 4 reviewers.
Rated 1.0 out of 5.0 by Useless drill bit Drill bit part of two pack. Drilled into hard wood door frame and snapped off before drill reached max RPM. I haven't used the other yet for fear that it might snap as well. July 9, 2014

Rated 5.0 out of 5.0 by Good Quality Keep the bit cool, I was using it to drill through 1/4" steel plates. I lubricated/sprayed a little WD-40 or PB Blaster to not overheat the bit. Drilled all the holes I needed and is still has sharp as the day I bought it. June 17, 2014
