Questions & Answers

I am planning to use this drill for tent stakes. We are camping in a place with relatively hard ground, and I would like to avoid using the mallets. Will this drill get me through hard packed dirt with the right screw in tent stakes?
ByAug 10, 2026

Answer This Question

Yes — the M18 Compact Drill/Driver will work with screw-in tent stakes for hard-packed soil if: Use spiral anchors (not straight rods). Run in low speed (1) for max torque. Pre-drill or moisten spot if ground is very compact.

          This drill can use on concrete
          ByFeb 8, 2026
          1 Answer | 
          Answer This Question

          Hi, Jack. Yes, the Milwaukee M18™ Compact Brushless 1/2" Drill/Driver can be used on concrete, but its effectiveness depends on the type of bit used. For drilling into concrete, you must use a masonry drill bit that is compatible with the 1/2" all-metal chuck of the 3601-20. Additionally, this drill delivers up to 550 in-lbs of torque and 0-1,700 RPM, which is sufficient for light-duty concrete drilling tasks, such as drilling holes for anchors or screws.

            I’ve had Milwaukee tools for years. Had to use my 1/2” hammer drill for concrete and it burned up. Had to replace it and I really like this drill. I’ve never used the hammer feature anyway. It came with a belt clip which is handy. I’m positive the shorter length will be helpful in tight situations.
            by
            Awesome drill and hammer feature. Also, love the impact gun also. Better combo and drill. Go red!
