    Powerful 21V brushless electric impact wrench!
    My sole purpose in purchasing this impact wrench was to get a nice, compact, brushless, powered impact needed to keep the wheel bolts and front loader mount bolts tight on a compact tractor. I haven't had a chance to use it for very long yet but I'm very happy with it so far.

    sturdy impact wrench
    This type of impact wrench can easily loosens suspension bolts and other hard to remove fasteners. It have one switch for forward/lock/reverse motion and can remove large bolts easier especially when it is difficult getting a breaker bar to access the bolt. It still feels sturdy although it is only 3kg.
