heavy-duty cordless drill typically has a higher voltage rating compared to a typical cordless drill. This higher voltage allows it to deliver more power and torque, making it suitable for more demanding tasks such as drilling through hard materials or driving large screws. While keyed chuck, battery pack, and variable speed adjustment are common features in both heavy-duty and typical cordless drills, the distinguishing factor for a heavy-duty drill is its higher voltage rating.
