          Flatter than a pancake after 2 holes
          I Drilled 2 holes and never made it through the second one. I was only drilling brick and didn’t even hit rebar. Definitely not up to the standards of quality I’ve come to expect from a Milwaukee product.

            Supposed to be good for concrete with rebar
            Bought two of these in case one fails. Good that I did buy two. My concrete has 6x6 steel wire mesh in it. My second hole I must have hit a rebar wire and it destroyed the bit. I have used the second bit to drill 8 more holes without issue.

            Disappointed
            First 2 mx4 5/32 drill bits destroyed in minutes working in concrete with rebar. At least in this size arent durable. The 3rd mx 5/32 last longer to finish the job

              7/8" bit but 29/32" Hole.
              Installing my MaxJax in new concrete with Wej-it (toggler.com) Epoxy anchors, I drill 1 hole and discover the fitment is loose. I then measure the bit and find 2 tips measure 7/8", but the other 2 measure 29/32" (see pictures) As I was on a time crunch, I ground-down the 2 tips that were way out of spec and finished the job, albeit slowly. So, the bit CAN do the job, and I might have gotten a manufacturing defect unit, but it's a crappy thing to discover when you "have to get the job done now"

                3/8" drill bit
                I bought this to drill holes in 6x6 landscaping timbers. I anchored the bottom timber into the ground with 1/2" by 2 ft rebar

                Bought to drill holes to install anchors for a MaxJax car lift.

                Broke during 1st drill.
                Bit snapped after 1st usage. It would not drill in the concrete. HD did not have this size in different brand so I went to another store and purchased a Dewalt bit and it drilled the 16 holes within minutes. It might have been a fluke but after breaking this bit, losing $ 16.97 and a few hours of my time I would not recommend the Milwaukee drill bit.

                  This drill bit is a beast!
                  This is the biggest SDS Plus bit they sell in store and it is a beast. I had to drill a hole through 4” concrete and this bit ate through the concrete within 20 seconds
