Milwaukee 18" Quik-Lok 7/16" Universal Extension 48-28-1040

MAXIMIZE REACH AND TORQUE TRANSFER WITH IMPACT-RATED PRECISION

The Milwaukee 48-28-1040 18-inch Quik-Lok Extension is engineered for the professional who demands mechanical efficiency and extreme durability in deep-hole drilling or high-torque fastening applications. Unlike standard extensions that rely on set screws or specific shank geometries, the universal Quik-Lok mechanism utilizes a proprietary internal locking system that secures all 7/16" hex shanks, regardless of whether they feature a power-groove. This design eliminates the common failure point of bit slippage and ensures maximum energy transfer from the impact driver to the work surface. Hardened steel construction throughout the shank provides the torsional strength necessary to withstand the repetitive shock of high-output impact tools, delivering a superior return on investment through extended tool life.

• / Universal QUIK-LOK™ design accepts all 7/16" hex shanks with or without power-grooves for maximum bit compatibility.
• / Impact Rated construction allows for use in high-torque applications without risk of shank failure or deformation.
• / Tool-free bit changes enable rapid transitions between drilling and driving tasks, significantly reducing jobsite downtime.
• / Hardened steel shank and optimized geometry provide superior durability and vibration resistance during heavy-duty use.
