  • Ever done this???

    Ever broken a selffeed bit? My first. This is a DeWalt bit. I have Lenox & Milwaukee also. This one did cut great when sharp with the double large cutting edge.

    By the way-it was sharp, sharpened right, there were no nails or knots in the wood, and the bit only made it in about 1/16".

    P.S. Didn't know exactly where to put this thread but I know alot of plumbers use these.

    I've had the same Milwaukee bits for 20 years, never broken one. Of course, I use them only once a year now but in the beginning it was every day.

    I sharpen them crudely with a carbide bit and it makes them sharp enough to get destroyed by the carpenters nails again.


    If the bit truely failed to no fault of yours, and it's a new one, I'd be asking DeWalt to cough up a new one.

      Never seen that before and I have drilled some pretty nasty holes too.

      Stop by a DeWalt service center and see if they will give you a new one. I'm pretty sure they arn't suppose to do that.

      I'm using the Lenox One-Tooth bits now and I'm very happy with those

        I have a couple of Lenox 1 tooths and they work pretty well. The first 2.5" I bought the tooth wall "kicked out" a little at the slot. Just enough when you compared it to a new one it wouldn't cut at all. The paint was still pretty fresh on it. Drilled maybe 10 holes.

        Finally ran into the Lenox rep by accident and got it replaced. The next one has drilled many holes with no problems.

        Think I'm going to get the Milwaukee Super Hawg 3 tooth bits. Have to order online though. Not one place here has them. I checked.

          I have never done that m because I would never use dewalt for that type of bit, they ,make better tools then bits

          But then again, just my opinion

          Agreed and my point exactly.

          I have been roughing houses since I was 16 using Milwaukee bits, ans I mean drilling through nails, all that nasty crap you do to bits and in fact I have never even seen an arbor break.

            I wonder if Dewalt changed there design on these recently...

            I just bought a 2" self fed Dewalt bit a few days ago and the design is different...hmmmm

            I went through a nail and thought "Well my new bit is toast" but to my surprise it did not show any damage...

            JC how old is that bit?

            Okie

              I'm gonna' guess the bit is a couple of years old. Believe it or not I had a Lenox selffeed bit in this size that "walked off the job" so I bought the only one available at the time. This DeWalt one.

              I believe the weakness has to be the double cutter. Lenox & Milwaukee only have 1 clearing blade.

                    The hole saw will work on rebar also. If you are hammer drilling in concrete and can expose the rebar take a hole saw and remove the pilot bit, cut what you can of the steel but not the concrete, hammer awhile and then the hole saw again. It works.

                      went to home depot on sunday to check the deals

                      ended up with $200. worth of deals

                      they have the 7 piece set of 3 tooth cutters in a case for $99.00.

                      it's 4 bits and the arbor and pilot with case.

                      a good package deal.

                        Thanks Rick. Checked 2 local Lowes, 1 Home Depot, 2 local supply houses, & 1 local/national supply house.

                        When I was near them of course. I'm not riding around wasting that much time.

                            looks defective to me.

                            maybe there was a crack to begin with.

                            jc, if you look closely at the shear mark, is there any rust or oxidation?
