The tradesman-tough Drive90 Plus attaches to the chuck to turn any power drill or impact driver into a right angle driver. What's more, the compact head design fits easily into tight spots where a standard drill won't go, like narrow stud and joist bays. The magnetic 1/4" hex socket holds all standard 1/4" driver bits for maximum versatility. Ergonomic handle has a flat side to aid perpendicular drilling. Grab one and turn the corner on a more efficient work day.
