1drill bit; so many holes!
I bought several of these bits, to drill into 1/4” angle iron to install a trailer bed. Based on cheaper brands, I thought I’d need a bunch of them to do the job. I used the 17/64ths bit. The first bit just broke off at hole number 60. Incredible quality to keep making hole after hole. After slogging through using cheapie bits, this is a pleasant relief. Totally worth the money. If you are using a 5/16th self tapping screw the 17/64th bit makes an excellent pilot hole. I’m sold on Milwaukee!

    CORRECTION
    I would like to take back my negative review for 7/64 Milwaukee Cobalt bit . The hole I was trying to drill was at the angle and at a difficult location. The drill bit is excellent. I never seen a bit flex so much and not break. P.S. HD, fix the picture and a title for the review pop up. It does not match the link!

      Waste of money & time
      Cannot drill through a piece of steel < 1/32' thick with a power drill. I gave up. Going to return this bit back to HD.

        works good
        I used this bit to drill through some small mending plates and it worked with no issues. I just started with smaller bits and worked my way up to this one. The tip of the bit is nice and bites into material good without slipping. The only dislike is that it is kind of expensive and I wish it could be included in the other cobalt milwaukee drill bit kit that I have. I have had this bit for about a week now and it does meet my expectations. Please hit thumbs up if this was helpful

          I like that this bit is meant for hard metal. This is a very sharp bit and does a good job of cutting. The downside that I've noticed is that the cutting edge of the bit easily chips. It's disappointing, considering how much it costs, for the edge to chip and break. If it doesn't chip it does a great job of cutting.

          I bought the bit because I needed to drill out a broken bolt on my exhaust system. I tried to start with a 1/8 inch then enlarge to 1/4, then 3/8 inch. The 1/8 nor the 1/4 would not even start to drill, a complete waste of money. I had even ground off the head so was only drilling the shank

          Expensive, but a good bit. I drilled 10 holes through 3/8" steel plate before the first bit seemed to be getting dull. I bought the second bit and it broke on the 1st try, so the original bit was used to finish all 18 holes. The photo was after 18 holes were finished.
