This Milwaukee kit features Shockwave impact driver bits with a Wear Guard tip that provides increased wear resistance, protecting the fit over the life of the bit. Each bit features Shockzone optimized for tip type and length to absorb peak torque and prevent breaking. Users can keep all 100 Shockwave impact driver bits organized in the included Packout compact low-profile organizer equipped. This Packout organizer is built from impact-resistant materials for durability on and off the Jobsite with no-travel bin seals that prevent migration of bits between bins. As part of the Milwaukee Packout modular storage system, you can custom-build storage systems to easily transport and organize your tools and accessories.
