Review on 🔨 DEWALT DW5400 Carbide Hammer: Ultimate 32-Inch Power and Precision by Jermaine Chowdhury

We used these drill bits to drill holes in a concrete wall for faucets. We had to drive in about 5000 screws using 75 bits. The bits broke after drilling 5 to 30 holes. We do this kind of work all the time so this wasn't our first rodeo. To be honest we tried Milwaukee, Bosch and Masterforce with the same result. The bits appear to be too long and will flex under the impact drill bit and snap. Tried multiple drills and multiple operators with the same result. Never understood what was wrong
