Review on 🔨 DEWALT DW5470 5 Piece Carbide Hammer: Max Performance for Superior Results by Christopher Clearfield

Very disappointed with the quality of these bits. I received them on Saturday and proceeded to drill holes to attach the bike rack to the concrete floor. The first 7 holes are drilled like a champion. On the 8th hole - it broke in the hole - there is no way to pull it out. That's a 5'2" woman, so I'm pretty sure I didn't rape the puncher and it shouldn't have broken. By the way, I'm suspicious because of the age of the drills - note the rust on the drills. and the photo was taken on Sunday - 1 day after opening the package. It looks like rust on the bits.
