SHOCKWAVE Impact Duty™ 3/8" Drive 10" Extension

The 49-66-6705 Milwaukee SHOCKWAVE Impact Duty™ 3/8" Drive Extension is a long-reach, high-strength 10" extension built to tackle deep or hard-to-access fasteners without sacrificing durability. Constructed from forged impact steel and engineered for high-torque applications, it delivers reliable performance and secure socket retention—because sometimes “almost long enough” just doesn’t cut it.
