The MILWAUKEE TOOL 48-32-4622 is a 6-inch square-drive power screwdriver bit built for use with impact-ready drivers and high-torque power tools. Machined from alloy steel, it is designed to handle the rotational stress of powered fastening without rounding or fracturing under repeated use. The 1/4-inch hex shank seats securely in standard quick-change chucks. At 6 inches overall length, it provides reach in recessed or hard-to-access fastening applications. This bit is suited for electricians, HVAC installers, plumbers, and general trade contractors who drive square-head fasteners on the job.
This screwdriver bit is intended for use in residential and commercial construction and mechanical trade work where square-drive fasteners are standard. It fits any power driver or impact driver equipped with a 1/4-inch hex quick-change chuck. The 6-inch length makes it practical for fastening in junction boxes, panel enclosures, equipment cabinets, and structural framing where a standard-length bit lacks reach. Licensed trade professionals installing electrical, mechanical, or structural systems will find this length useful for production fastening tasks.
Designed as an OEM-style replacement or supplemental bit for power drivers and impact drivers equipped with a standard 1/4-inch hex quick-change chuck.
Insert the 1/4-inch hex shank fully into the driver chuck before operating. Verify the bit is seated and locked before applying torque. Inspect the bit tip for wear or deformation before each use — a worn tip increases the risk of cam-out and fastener head damage. No special tools or certifications are required for bit replacement; follow the tool manufacturer's guidelines for chuck operation and torque settings.
