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 acce more→ssories 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.

The Milwaukee Shockwave 3.5 in. Impact Duty Torx Bits are engineered to be the most durable, best fitting driver bits on the market. The Wear Guard Tip delivers increased wear resistance which protect more→s the fit over the life of the bit. The Shockzone is optimized for each tip type and length of driver bit to absorb peak torque and prevent breaking. The Custom Alloy76 has customized steel and heat treatment per tip type to extend the life of the driver bits, providing up to 50X life vs. competitive impact driver bits. The Milwaukee Shockwave driver bits are built to deliver extreme durability for the most demanding applications.

IRWIN Speedbor MAX Speed Bits features three cutting spurs for faster, cleaner holes, less breakout, and extended drilling life
