Bosch wild bore is better
I used this bit for granite in my yard. It worked for a while but was slower and eventually broke. I found the Bosch wild bore to be faster and better. I can get 3 holes per battery vs 2 with the Milwaukee.

    I was a bit hesitant to buy Milwaukee brand but since it was the only brand available at the store that day that had the diameter size I needed. I used this drill bit in recently poured concrete post, to install a retrofit bolt anchor. Worked well and made easy work of drilling on the concrete.

    Fast Cutting
    This is a well made (in Germany) concrete bit (suitable for rebar contact) for use with SDS-MAX hammer drills. It is advertised as a 4 cutter bit, two full width and two partial (see photo). The "variable flute" design (which is deeper than other bits I have used) results in faster and more complete evacuation of drilling "dust" from the hole being drilled, with less frequent need to pull the drill out of the hole to clean the hole. The carbide protrusions on the side (for encounters with rebar) are longer in length and do not stick out as far as other bits, increasing their resistance to damage. I did not get a chance yet to see how it performs with rebar present, but in an unreinforced 4 inch concrete slab, it drilled through like it was butter. All four of the cutting surfaces communicate with the flutes, for material removal, not just the primary full width cutters. The manufacturer claims 20% faster drilling than others, and, based on the reduced frequency of stopping to remove the drilling residue alone, I have no reason to doubt it.

          Doesn’t last ling
          The first hole went quick and smooth, but it would not drill another. I tried drilling in three different locations, but the bit was a one and done. I would not recommend this, unless you have only one hole to drill
