I have never understand why so many people use impact drivers to drill holes. They are designed for high torque applications. I can easily out drill an impact gun with an old school brace and bit. The other day I watched a framer drilling 3/4" holes in 2X mud sills for foundation bolts. Probably took 20 seconds a hole. I could drill that same hole with my cordless drill in about 3 seconds.
I highly recommend the Milwaukee M18 Hole Hawg. My lead guy was bugging me for a while to get some to try but I was leery it could replace a standard Hole Hawg. I finally broke down and purchased 2 to try. I was wrong! They can drill just as fast with the cordless Hole Hawg. They work really well paired with the 9.0 batteries. You don't need the Super Hawg version for most applications.
I have my guys set up with all Milwaukee M18 drills, sawzalls, circular saws, angle grinders, multi tools. The only thing they still plug in at job sites is the charger.
