With the Milwaukee Shockwave Knuckle offset attachment, you drive screws effortlessly into tight spots where a regular drill or driver cannot fit straight. The pivoting holder locks securely at 0° or 30°, giving you a compact 40 mm profile to reach behind pipes, between framing, and inside tight cabinetry. Engineered for heavy impact duty, its solid metal build easily absorbs the high torque of powerful 18V impact drivers. Complete with a standard 1/4" hex shank and ten included screwdriver bits (PH, PZ, and TX), this versatile set keeps your fastening work fast, accurate, and under control.
