Only used one bit once to drill through aerated concrete wall. Worked great.
Well crafted. Product works great and price is right.
Getting this set is a pretty economical way to go. I really only wanted extra 1/4 and 1/2 bits, because I can never seem to find the ones I own when I need them, but it was cheaper to buy a set than to buy just a couple of bits.
Nice set for the price. Really only needed the 1"1/4, but like having options. Especially like that they are quick change bits. Easy to take in and out of my drill.
