    Q:I have to drill out a set screw in a gas block on my rifle. I broke off a Fit It Stick bit in the set screw. Start with 3/32?, then 7/64? and finally 1/8? if necessary. Hopefully, I can dislodge the remaining material without damaging the threads.

    Answer This Question

    A:  Hello friend, for this application, First I would try to use a mechanics pick for the broken fit stick. Then try a lisle, etc. extractor. If that doesn't work you can also use a left handed drill bit which often spins the damaged fastener out.

          Milwaukee Cobalt bits above 1/4" in are junk
          I only own Milwaukee cobalt drill bits because I found they are the best to drill in 1/4 and 3/8 mild steel fast and multiple holes. However, the 3/8 bits and larger that have a pilot point loose their drilling ability just after 1.5 holes. I bought 2 new ones from HD and was able to drill 1.5 holes with each bit before they stopped drilling. I was using cutting oil and a Makita 18v drill. Unfortunately pilot point bits cannot be sharpened and fortunately HD took them back

            Defective, second bit purchased from Homedepot
            It seems that every Milwaukee bit I have purchased from Home Depot is defective. I purchased the 5/16 metal bit about two months ago and finally found the time to drill holes in 14 gauge sheet metal and all I could get done were 8 holes, that's even using the bit with tap magic. Absolutely terrible.

              Awesome strong bit to do a crank pin.
              I needed a very strong bit to drill a Hellcat engine driveshaft and a balancer/pulley. With a special tool to keep the drill from moving away and enough oil to lubricate and keep temps cool, I was able to drill it within minutes

              When drilling on the first metal strip to make a hole was easy but on second and third holes were not easy. It is for the sunscreen shade to hold.

                Great bits
                These Milwaukee impact bits are my second favorite bits after the Milwaukee cobalt bits. I keep at least two full sets of each at all times. They’ll chew through 1/2” steel all day long. The cobalts cut faster, but I like the quick connect feature for the impact on these.
