The Milwaukee® Shockwave™ right angle adapter features an Internal Optimized Shockzone™ which absorbs peak torque and prevents breaking. The shanks are made from Custom Alloy76™ steel which is engineered for extended life. The hardened gears provide increased torque transfer for added durability. With only a 1.4 in slim profile, the adapter allows access into the tightest of spaces. The Shockzone™ right angle adapter is designed for use in both impact drivers and drill drivers and works with all 1/4 in hex shank accessories.
