Review on High-performance Chicago Latrobe Cobalt Length 29 Piece Set - Unbeatable Quality and Versatility! by Jake Davies

I bought these drills hoping for something more durable than the $30 sets you buy at Lowes or Home Depot. While working on a spiral staircase project at my house, 3 of these parts broke in just a few minutes, forcing me to go back to the cheap parts I had before. While the lower quality beats took a little longer, at least they didn't break, which was the case with these beats. So much for paying little, or in this case a lot more, for quality tools.
