Well honestly these are the best drills I've ever used. I've been a maintenance mechanic for 30 years and I was very skeptical. I just bought a pack of Westward on Facebook and they suck compared to these. A short chisel is way better than a jobber length in my opinion. Yesterday I used them to drill through 1" x 1/4" stainless steel and they cut like butter. At the end of the day, the 1/4" stainless steel bolt broke in the welded 1/4" stainless steel nut. Started small and gradually used a larger piece. 3 bits and hunt and repair were done. I'm a lifelong fan and now watch bigger sets.
