Milwaukee Tool 49-66-6611 Impact Socket 1 in Drive 56mm

Product Description

The MILWAUKEE TOOL 49-66-6611 is a 1-inch drive, 56mm, 6-point hex impact socket designed for heavy-duty fastening and removal applications. Built from steel with a black phosphate finish, this standard-length socket resists corrosion and withstands the high-torque output of 1-inch drive impact wrenches. The non-sparking construction makes it suitable for use in environments where ignition hazards are a concern. It is intended for installation by industrial maintenance technicians, millwrights, heavy equipment mechanics, and other trade professionals working with large-diameter fasteners.

This socket fits 1-inch drive impact wrenches and is sized for 56mm hex fasteners commonly found on heavy equipment, industrial machinery, and large structural assemblies. The 6-point drive geometry provides full contact with fastener flats, reducing the risk of rounding under high torque. Standard length makes it a straightforward fit in most service and maintenance scenarios where clearance is not restricted. The non-sparking designation suits applications in petrochemical, mining, and other hazardous environments where spark-free tooling is required.

Key Features

• 1-inch drive fits standard heavy-duty impact wrenches
• 56mm socket size for large-diameter hex fasteners
• 6-point contact geometry reduces fastener rounding under high torque
• Non-sparking construction suitable for hazardous or ignition-sensitive environments
• Black phosphate finish for corrosion resistance
• Standard length for general-access fastening applications

Compatibility

Designed as an OEM-style impact socket for use with 1-inch drive impact wrenches requiring a 56mm hex socket.

Installation Notes

Installation and use should be performed by qualified mechanics or trade professionals familiar with impact tooling. Always confirm the drive tool is de-energized or disconnected from the air or power supply before attaching or removing the socket. Do not use impact sockets with hand-torque ratchets, as impact-rated sockets are designed specifically for the shock loads produced by impact wrenches. Follow applicable workplace safety standards when operating in classified hazardous locations.
