These bits never break in my experience.
[This review was collected as part of a promotion.] This is a great bit. We use it for drilling into cement floors to install lag bolts, etc. It goes quite a while before it starts to show any wear. DeWalt makes great bit. We only use their bits when doing any heaving drilling.

      Superior SDS+ drill bit
      [This review was collected as part of a promotion.] Having put the DeWalt 1/2" x 10" sds+ drill bit through an intense brick wall job it proved to be a superior design. The cutting power of the bit along with it's hammer action made short work of the 4 inch diameter opening needed in a brick wall job. Precision cutting as well as hammer action achieved a clean result. Thanks DeWalt, for taking sds+ bit engineering to the next level.

        Like a hot poker thru snow!
        [This review was collected as part of a promotion.] I got this 1/2" DEWALT SDS bit and was I amazed. It drilled thru the concrete and rebar like nothing. The best part is how long it lasts. I drilled over 100 holes for 1/2" lags for pallet rack I installed in a warehouse. Got the job done fast and the bit still looks and drills like new. This bit made me more money that day.

          Just an amazing bit
          [This review was collected as part of a promotion.] I had to anchor metal shelves into a concrete floor and cinder block walls. Making holes for the anchors was fast and easy. It made my day go quick.

              Seems durable
              [This review was collected as part of a promotion.] Used this in my new hammer drill. It stayed suprisingly sharp after many uses. I don't know how long it will hold up but I am prety pleased so far.

                    [This review was collected as part of a promotion.] This was the first time I used Dewalt bits exclusively and I can honestly say I am sold. Already stocking up each time I go for supplies so I have any bit for any project I am working on

                      Good value in a hammer bit
                      [This review was collected as part of a promotion.] The Dewalt SDS+ hammer bit did a good job in my applications of drilling through concrete and tile. It cuts fast and stays sharp. In the past I used Bosch carbide bits and I would say these are just as good, if not better, while being similarly priced. Definitely worth a look.

                              [This review was collected as part of a promotion.] This bit works. Plain and simple. I use it for hanging rod to secure the pipe I install. Tough bits stand up to reinforced concrete.

                                This bit far out performed anything else that Home Depot offers. Drilled 25 holes in concrete foundation blocks and the bit is still good to go for more.

                                A bit with great bite!
                                The Dewalt bits always perform well for me and my crew and they last longer than other brands used in the past.

                                Performed as expected, I now have a 3/4" PVC conduit through my 6" concrete foundation wall and plenty of life left on the bit to do it again and again and . . .

                                Did the job
                                Need to sell bits in the store. Had to order online. Took to long to get it. 1-1/8 inch is a must have size if going to put 3/4 pipe or conduit thru a brick or concrete wall. Home Depot sells 3/4 pipe and 3/4 conduit. BUT they do not sell bit large enough to install them. A 3/4 pipe has a 1-1/16 inch outside diameter. I needed to bring my generator wires thru the wall and the wires would not fit in 1/2 inch conduit. Other people must have the same problem. Maybe Home Depot should sell the bits in the store but rent the drill. I have a drill but most people don't.
