          Five screws.
          THIS SNAPPED AFTER FIVE SCREWS. The tip snapped right off. I’m using a basic 20V Max XR.. nothing that powerful. This is a GARBAGE bit and sadly, these days, a garbage brand.
            Rusting after being in sealed work van for 1 night
            80 dollars worth of insert bits were in my work van for 1 night and the next morning there were rust spots all over every new bit . Older bits and dewalt bits don’t have any rust at all .. what’s going on with these new insert bits ? Anyone else having these issues ?

              Indispensable bit for hurricane shutters
              PH3 bits are an absolute necessity for my hurricane shutters. These Milwaukee PH3 bits were just as important as the charged battery and the hammer drill. They were absolutely sold out at the nearest Home Depot. Thank goodness I had these.

              Shockwave Bits for the win!
              I use these on Pierce fire trucks all the time. Hammering in shooter screws and other stainless hardware all day, these things take a beating! They don’t strip bolts and they don’t break like other cheap bits. These things are the real deal!

                  I would purchase this again
                  I used this in every job that I’ve done and the quality and hardness of the actual bit is very good

                    Great bits
                    Awesome bit. Doesn’t strip. This product works really well with the hex impact.

                      This bit holds up to the everyday wear and tear.
                      I love this bit, it holds up to the everyday wear and tear that we put it though.

                        Same bit
                        I use this 5 to 6 days a week in HVAC, It’s nice and pleasant that I haven’t had to replace it, usually any other brand bits tend to brake on me

                          Thank you!!! What a great product!!!
                          I'm a elevator mechanic apprentice, and I've started buying my own tools to build my gear up. So I decided to take the dive and go with Milwaukee, and I couldn't have been happier. From the bits, to the grinder. Everything has done its job over any expectations I could had. So once again thank you for making my trade easier! Chris A.
