Milwaukee Tool 49-66-6509 Impact Socket 1 in Drive

Product Description

The MILWAUKEE TOOL 49-66-6509 is a 1-inch drive, 1-5/16-inch, 6-point hex drive impact socket built for heavy-duty fastening applications. Constructed from steel with a black phosphate finish, this standard-length socket is engineered for use with 1-inch drive impact wrenches in high-torque environments. The non-sparking construction makes it suitable for use in locations where ignition risk is a concern. At 2.23 pounds, it delivers the mass and wall thickness needed to handle the sustained shock loads generated by pneumatic and electric impact tools.

This socket is used in industrial, construction, and mechanical applications requiring a 1-inch drive platform. Standard-length geometry keeps it compatible with typical impact wrench anvils and deep sockets are not required for this application. It is commonly installed by millwrights, heavy equipment mechanics, ironworkers, and industrial maintenance technicians working on structural fasteners, machinery, and equipment with large-format hex fasteners.

Key Features

• 1-inch square drive fits standard 1-inch drive impact wrenches and breaker bars
• 1-5/16-inch socket size for large hex fasteners
• 6-point geometry maximizes contact surface and reduces rounding of fastener corners
• Non-sparking construction suitable for use in environments with ignition risk
• Black phosphate finish resists corrosion and reduces glare
• Standard length profile for general-purpose impact applications

Compatibility

Designed as an OEM-style impact socket compatible with 1-inch drive impact wrenches, torque multipliers, and breaker bars using a standard square drive interface.

Installation Notes

Installation and removal should be performed by qualified mechanics or technicians familiar with impact tooling and torque requirements for the fastener being driven. Ensure the socket is fully seated on the impact wrench anvil and the retaining pin or ring is secured before applying load. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Follow applicable industry safety standards when operating impact tools in potentially flammable or explosive atmospheres.
