Milwaukee 49-66-6711 Impact Duty Extension 3/4 in Drive 10 in

Product Description

The MILWAUKEE 49-66-6711 is a 3/4 inch drive, 10 inch impact duty socket extension built for high-torque power tool applications. Forged from impact steel, this extension is designed to handle the stress of impact wrench use without fracturing or deforming. Laser-etched markings identify the drive size and length at a glance, saving time during tool changes. A dual-hole design combined with a ring groove simplifies attachment and removal, while a ball detent mechanism keeps impact sockets seated securely under load. This extension is sold individually and meets ASME industry standards.

This extension is suited for professional trades requiring reach into confined or recessed fastener locations. It is optimized for use with 3/4 inch drive impact wrenches in heavy mechanical, industrial, and construction applications. The 10 inch length gives added clearance when working around obstructions or inside deep cavities. Mechanics, millwrights, ironworkers, and other trades relying on high-torque impact tools will find this extension a practical addition to their socket set. All MILWAUKEE SHOCKWAVE Impact Duty extensions carry a Lifetime Guarantee covering impact sockets and extensions.

Installation Notes

This extension is installed and removed by hand; no tools are required for attachment to the impact wrench drive. Ensure the ball detent is fully engaged before applying torque. Inspect the extension and socket for cracks or deformation before each use, and replace any damaged components immediately.
