Question: Do they bits come with a case??
Document: Dewalt seems to always come through with quality control of Made in China products.I have not used these bits yet.
Awesome bits. Power right through anything they pretty much come across. Very worth the price you get what you pay for w/ tools.
These drill bits are excellent! It was like I was drilling through butter!
Bought these bit along with my Dewalt SDS Hammer Drill. These bits have been abused and just keep on truckin'.
Bought these bits with a DeWalt hammer drill for my husband - he likes them a lot - says they're nice bits.
These bits have drilled so many holes I wouldn't even try to guess a count. Nice set for normal plastic anchors or lags and other holes.
These are the best masonry bits I've ever owned... and ever used. They go through block wall and concrete like butter. Highly recommended.
These are the short bits. Fit and work, haven't used a lot, mainly needed the longer ones I also got for running cable through block walls and through poured floors. These are good for mounting things on concrete walls.
The Dewalt DW5470-5 Hammer Bit set was purchased and used with my Dewalt Hammer Drill. The bits work extremely well. I use them for my patio business to install lag bolts or holding devices in concrete.
I'm not sure what these are shanked to go into. I just chucked them up in a standard chuck hammer drill and went through a cement floor like butter. I don't know if I should give credit to the bits or the drill, so I'm giving credit to both.
