Milwaukee 49-66-4461 Deep Well Impact Socket 3/8 in Drive

Product Description

The MILWAUKEE 49-66-4461 is a 1/2 inch deep well impact socket with a 3/8 inch drive, built for heavy-duty fastening applications in the trades. Manufactured from chromoly steel and heat treated for controlled hardness, this socket is rated for use with impact drivers and impact wrenches. The 6-point design maximizes contact with fastener flats, reducing the risk of rounding under high torque. At 3.0 inches in length, it reaches fasteners seated deep in recesses where standard-depth sockets cannot. Etched size identification is stamped directly on the socket body for quick recognition in a busy tool bag.

This socket is suited for residential and commercial installation work across HVAC, plumbing, electrical, and general mechanical trades. It is intended for use with 3/8 inch drive impact wrenches and drivers in applications requiring deep fastener reach, such as equipment mounting, panel work, and mechanical assembly. The individual format makes it a practical addition to any existing socket set or impact kit. The black oxide finish helps resist corrosion in field conditions.

Installation Notes

This socket is intended for installation by trade professionals using impact-rated drive tools. Ensure the socket is fully seated on the drive anvil before applying torque.
