Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Cut's out 1/2" KO Hole Needed to install a 1/2" fitting into an electrical box where no KO existed. A bit on the costly side. Drilled through the steel with some ease. Hole was a little oversized, however. The spring around the drill helped to "eject" the cut slug. The center pilot drill keeps everything going true. November 20, 2013
Rated 5.0 out of 5.0 by Put down the knock-out punch! These Klein carbide cutters are pretty much all I use nowadays for electrical knock-outs in the smaller sizes - other than enlarging a hole, obviously. Being in the trade for almost 30 years, I have been admittedly a little slow to trying new ways of doing things at times, but I'm sure glad I finally got around to purchasing a couple of these.
