Published on 16/08/2016, FranceI've already drilled at least 15 holes with this 30mm drill bit through a slab of reinforced concrete. The drill bit is still as new despite coming into contact with the reinforcement. It's excellent value for the price.

Published on 17/12/2017, FranceIt's a good product but I think it would have been better with a 4 headed tip because it's tough to use if you hit a reinforcing bar.

Published on 09/10/2018, FranceForest that allows to cross a slab very easily. This length is to be recommended because with the extra thickness (2 heights of tiling, coping and ourdis), it would be too fair with a 350.
