Impact Ready Bits with FlexTorq, 40 pieces, are perfect for impact drivers since they are more durable and have a longer lifespan. Bits can bend thanks to Reflex Core technology, which lowers breakage. Bit drops are reduced by the 10x Magnetic Screw Lock mechanism, which keeps you productive at work. Extra FlexTorq Zone* transfers the correct torque, and a precision-machined tip provides the perfect fit in fasteners to reduce screw stripping.
