Review on Drill America Qualtech High Speed Conventional by Brandon Gaines

These bits are absolute rubbish. I assume they are from abroad. I broke 4 bits on about 8 holes. One bit didn't even make it to the full hole. Another bent while drilling. I drilled out a 2x4 and then a 17 gauge standard 2-3/8 inch metal post. Another "K" drill bit I used to use (which I believe was made in America) made at least a hundred holes before I had to replace it because it was dull. These drills never dull because they break long before they dull. If you only drill wood, okay everything else, don't buy them.
