This thing is amazing, good for hard to reach places. The emergency lock is perfect. The permanent handle is well positioned, the detachable arm is very sturdy. Don't be fooled by a few other bad reviews. This permanently replaces my wired Milwaukee Hawk of the same style. If this is your only 60v tool then you will need more than 1 battery. I drilled about 10 holes in 100 year old oak with a fairly boring 3 5/8 inch self-propelled hole saw and a fully charged battery. Tons of power despite drilling 3 1" x 16" self-supply holes through a new head and 2 100 year old deck plates with amazing ease and speed. If you deal with electrical or plumbing, you need this tool. I used Milwaukee's cordless little M18 nut, it was great for electric like 1" bits and single bolts. But it doesn't stick to that. There's some beef in there. I wouldn't want to go camping with him.
