Milwaukee 48-28-1000 Quik-lok Bit Extension 3in 1/4in Drive

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-28-1000 is a 3-inch, 1/4-inch shank bit extension designed for use with impact drivers and drill/drivers in professional trade applications. Built on a hardened shank, it accepts all standard 1/4-inch hex shank bits and delivers tool-free quick-change capability through the Quik-Lok mechanism. The impact-rated construction handles the high-torque demands of fastening tasks on jobsites where standard extensions fail prematurely. Electricians, plumbers, HVAC techs, and general contractors rely on this type of extension when working in confined spaces or when added reach is required to drive fasteners into recessed or obstructed locations.

This extension is suited for residential and commercial construction, mechanical rough-in, and service work. The universal 1/4-inch hex shank fits the collets of standard impact drivers and drill/drivers from most major tool manufacturers. The Quik-Lok collar allows bit swaps without removing the extension from the tool, reducing downtime during repetitive fastening operations. It is equally useful for wood screws, self-tapping metal screws, and sheet metal applications common in HVAC duct work and electrical panel rough-in.

Key Features

• 3-inch overall length adds reach in confined or recessed fastening locations
• Quik-Lok mechanism allows tool-free bit changes without removing the extension
• Accepts all standard 1/4-inch hex shank bits
• Impact-rated construction handles high-torque output from impact drivers
• Hardened shank for extended service life under repeated impact loads

Compatibility

Designed as a universal-fit accessory compatible with any tool accepting a 1/4-inch hex shank drive, including standard impact drivers and drill/drivers.

Installation Notes

Insert the 1/4-inch hex shank into the tool collet until it seats and locks before operation. When swapping bits using the Quik-Lok collar, ensure the tool is powered off or the trigger is locked out before handling the extension tip. Inspect the shank and locking collar for wear or deformation periodically, and replace the extension if cracking or slippage is observed under load.
