12" x 3/8" Bit Extension

Product Description – Milwaukee 48-28-4008 Bit Extension

The Milwaukee 48-28-4008 is a 12-inch drill bit extension designed to extend the reach of hole-saw arbors and drill bits with a 3/8-inch hex shank. It allows users to drill deeper holes or access tight and recessed areas without repositioning the drill.

The extension features a 3/8-inch hex shank that fits standard 3-jaw drill chucks, making it compatible with most drills that have 3/8-inch capacity or larger. A hex-wrench locking system secures the accessory to the extension for stable operation during drilling.

Built from durable steel or high-speed steel materials, the extension is designed for demanding construction and maintenance tasks, especially when working with hole saws and similar cutting accessories.
