A heavy-duty wood-boring Stud and Joist Drill (model DWD460) from DeWalt has an anti-bind, anti-stall feature that automatically adjusts motor torque when bits bog down. Designed for boring large holes into wood using ship auger bits, hole saws, and self-feeding bits, this corded tool's 11-amp motor offers two variable speed ranges from 0-300 rpm and 0-1,300 rpm. The drill includes a mechanical torque-limiting clutch for low-speed drilling, and a 1/2-inch chuck. Price: $339. 800-433-9258.
