3/8" drill bit
I bought this to drill holes in 6x6 landscaping timbers. I anchored the bottom timber into the ground with 1/2" by 2 ft rebar

Carbide tip sheared off.
Drilled five holes in concrete and had the tip shear off on the sixth one. There was a tie wire near the last hole, but I didn’t think anything of it since it was rated for concrete with rebar. Took it back to HomeDepot but it was past the 90 day return policy by about three weeks. Talked to the Milwaukee rep at Homedepot and she wasn’t able to be much help. Maybe I just got a bad bit, but definitely hasn’t even come close to some of the other brands of bits that I have for my drill. Waste of time and money!

We are sorry to hear about your experience with this Carbide bit. We would love to learn more about what happened. Please email us at socialmedia@milwaukeetool.com. -Cayla with Milwaukee Tool
    Broke during 1st drill.
    Bit snapped after 1st usage. It would not drill in the concrete. HD did not have this size in different brand so I went to another store and purchased a Dewalt bit and it drilled the 16 holes within minutes. It might have been a fluke but after breaking this bit, losing $ 16.97 and a few hours of my time I would not recommend the Milwaukee drill bit.

      This drill bit is a beast!
      This is the biggest SDS Plus bit they sell in store and it is a beast. I had to drill a hole through 4” concrete and this bit ate through the concrete within 20 seconds

        This bit ate right through my 10-day old concrete footings without breaking a sweat. Drilled 9 holes @ 5/8” diameter about 5.5” deep and each hole took maybe 10 seconds. Didn’t encounter rebar so I can’t speak to how well the bit cuts thru steel, but for concrete, it was great. I don’t have the need for drilling 5/8” holes in concrete often, but you can’t go wrong with this bit.
