Both compact power tools are powered by REDLITHIUM batteries, providing users with unmatched power, speed, and tool belt portability. The Wear Guard Tip delivers increased wear resistance which protects the impact bit’s fit over the life of the bit. The Shockzone is optimized for each tip type and length of driver bit in the set to absorb peak torque and prevent breaking. The driver bits have Custom Alloy76 for a customized steel and heat treatment per tip type to extend the life of the user’s driver bits, providing up to 50X life versus other impact driver bits on the market. The Milwaukee Shockwave driver bits are built to provide users with extreme durability for the most demanding applications.
