Milwaukee 49-66-6819 1/2 in Drive Socket Set 27-pc

Product Description

The MILWAUKEE 49-66-6819 is a 27-piece SHOCKWAVE Impact Duty socket set engineered for 1/2 inch drive impact wrenches, drivers, ratchets, and adapters. Built from high-strength forged impact steel with a 6-point design, the set handles high-torque applications without fastener rounding. Each socket carries stamped and ink-filled size markings for wear-resistant identification throughout the life of the tool. The case measures 12.8 inches long by 8.27 inches wide by 2.5 inches tall and the set weighs 7.37 pounds. Licensed HVAC technicians, plumbers, electricians, and mechanical contractors reach for this set when impact tool work is part of the job.

This set covers both SAE and metric fastener sizes in a single tray, making it a practical choice for residential and commercial mechanical work. The removable tray is compatible with MILWAUKEE PACKOUT Organizers (48-22-8435) and (48-22-8430) and fits standard tool chest drawers. Included sizes span 10mm through 24mm on the metric side and 3/8 inch through 1-1/8 inch on the SAE side, covering the fastener range common in equipment installation, service panel work, and mechanical room applications.

Installation Notes

Impact sockets should only be used with impact-rated drive tools — do not substitute standard chrome sockets in impact applications. Inspect each socket for cracks or deformation before use, particularly after high-torque service. Trades working near energized equipment should confirm the drive tool and socket combination meets applicable safety requirements for the work environment before proceeding.
