ImpactX??? is a line of impact-rated insert bits and fastening accessories built specifically for the demands of the professional contractor. Professionals require commercial duty bits and fastening accessories that can endure the force of high-volume screw driving applications with high-torque impact drivers. Standard screwdriving bits are brittle and fit poorly into fasteners and in applications with high-torque impact drivers this losing combo quickly leads to broken bits. ImpactX??? hits back with improved fitment and increased performance with high-torque impact drivers. Precision machined (not forged) tips ensure full contact fit, while performance-optimized and heat-treated S2 steel provides more flex and more durability than standard, brittle bits.
