Product Description
Milwaukee 5-1/2 in. x 7/16 in. Universal QUIK-LOK Extension
Model Number: 48-28-1030
The Milwaukee 48-28-1030 is a 5-1/2 in. x 7/16 in. Universal QUIK-LOK Bit Extension — a compact extension shaft with Milwaukee's QUIK-LOK quick-change bit interface for adding reach when driving fasteners or drilling in applications where the driver's chuck is not close enough to the work to reach the fastener location with a standard bit alone. The 7/16 in. hex shank size is the larger hex format used with heavy-duty drivers and impact wrenches that use the 7/16 in. hex collet chuck rather than the standard 1/4 in. hex, providing compatibility with Milwaukee's M18 FUEL and other impact drivers equipped with the larger 7/16 in. hex bit retention system. The QUIK-LOK interface accepts 7/16 in. hex shank bits and accessories with a tool-free push-in engagement, releasing them with a collar pull for fast bit changes without opening or closing a chuck mechanism.
The 5-1/2 in. compact length adds modest reach while keeping the overall driver-plus-extension length manageable for use in moderate-clearance confined spaces — applications including reaching screws recessed into counterbored holes, accessing fasteners inside shallow cabinets and enclosures, and providing the clearance between the driver chuck and the work surface needed to clear adjacent structure or materials during driving. The compact extension length minimizes the leverage disadvantage and deflection tendency that longer extensions introduce during high-torque impact driving, maintaining reasonable driving accuracy and control at 7/16 in. hex impact driver force levels. The universal bit receiver accepts the standard 7/16 in. hex shank found on heavy-duty driver bits and accessories across Milwaukee and compatible manufacturer products without brand-specific compatibility restrictions.
See Milwaukee's complete QUIK-LOK extension lineup for additional lengths and for the 1/4 in. hex standard driver extension series that covers the broader range of driver and drill applications.
