Dewalt's FlexTorq IMPACT READY accessories now come in ToughCase+ system, the latest addition to our accessory storage line. The ToughCase+ system is a connectable case system designed to optimize storage space and keep your bits organized. The 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. FlexTorq IMPACT READY accessories deliver exceptional performance for extreme torque applications. FlexTorq bits in the bit driver set feature an Extended FlexTorq Zone* to transfer optimal torque in hard joint applications, providing durability and longer life.** The bit tip is CNC machined for a precise fit, reducing cam-out under torque.
