Our IMPACT READY screwdriving accessories now come in ToughCase+ system, the latest addition to our acccessory storage line. The ToughCase+ system is a connectable case system designed to optimize storage space and keep your bits organized. The patented bit-bar design of the drill driver set allows for easy bit removal and the clear lid allows you to see inside at a glance. Specifically made to handle the force from impact drivers, IMPACT READY bits in the bit driver set are made of a special steel designed to be ultra-durable. Each bit uses a black oxide process for greater wear resistance and strength. The tips can be used with impact tools rated for up to 2,000-inch/lbs. of torque.
