Milwaukee 48-28-40XX Bit Extension 12"

Milwaukee 48-28-4008 12" x 3/8" Bit Extension

The Milwaukee 48-28-4008 Bit Extension is engineered to extend the reach of your driver or drill, giving you the extra length needed to drive and seat fasteners in recessed, deep-set, or otherwise hard-to-access locations. Measuring 12" in overall length with a 3/8" size, this extension bridges the gap between your power tool and the workpiece, helping you maintain control, alignment, and driving accuracy even when the fastener sits well below the surface or behind an obstruction. It's a simple, purpose-built accessory that adds versatility to a driver or drill already on hand, rather than requiring a dedicated long-reach tool for occasional deep-access work.

Key Features

• Trade Size: 12" x 3/8" extension length and size, sized to extend the working reach of compatible drivers and drills.
• Extended Reach Design: Adds a full 12" of length between the tool and the bit, allowing access to fasteners set deep in cabinetry, framing, equipment housings, and other confined spaces.
• 3/8" Fit: Sized for use with 3/8" bits and compatible driving and drilling accessories, helping maintain a secure connection while in use.
• Straight-Line Transfer: Designed to carry torque and rotation from the tool through the extension to the bit for consistent driving performance at extended reach.
• Jobsite-Ready Accessory: A straightforward add-on that keeps a driver or drill working in situations where a standard-length bit simply can't reach the fastener.
• Compact for Storage: Fits alongside standard driver bits and accessories in a tool bag or case for easy access when an extended reach is needed on the fly.
