Answer This Question

A:  Yes, just use some kind of cutting oil and keep the speed down to avoid aluminum chips fusing to the teeth.

          works great
          This is a great set I really only need two bits but this was a better deal than buy the two bits separately. When yoy have extra bits they always come in handy on those odd ball projects or remodels.

            Defective product - would not buy again.
            Failed to cut through a thin walled garbage can out of the box. After reading the review I discovered my kit didn't have the spring or ball bearing in the arbor.

              Very durable, long lasting hole saw. I have owned many sizes of this brand over the years. No need to look any further. The price is great for the excellent quality.

              missing pieces only 19 not 21 and used
              Opened the box and everything was just thrown in the box with all of the holding sticks everywhere and a used 3/4 hole dozer, i know its a great product so i cant be mad but just wished it came properly assembled and not with a used but or missing item

                Milwaukee 13 piece hole dozer kit
                The only problem I had with my kit was two of the hole saws (.3/4” & 1-1/8”) did NOT fit either of the threaded drill attachments #49-56-7250 or #49-56-7040 both were slightly larger but fit the rest of the hole saws. I had to go to the store and get a “individual 3/4” hole saw with a threaded drill attachment which that part number was #49-56-7010 hmmmm? Why would Milwaukee sell a multiple hole saw kit with 2 threaded drill attachments that DON’T fit two out of the nine hole saws, leaving you to get a separate threaded attachment. I thought it was a defect at first only to find out having to shell out more cash. SMH.

                  Milwaukee hole saws.
                  Some of the hole saws in the kit were out of round. Not very well made.

                    Incomplete Kit
                    Kit came in fast, unfortunately the kit I got was a return or an open box, unfortunately it came missing a bit and the arbor bit. Contacted Milwaukee and they said to return to HD. Home Depot can’t return since I threw out the paper label it came wrapped in.

                      Wrong size arbor
                      My kit did not come with the smaller sized arbor. Both arbors are same size
