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.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Milwaukee 48-28-4006 – Frequently Asked Questions

1) What is the difference between Milwaukee bit extension 48-28-4006 and 48-28-4008?
Both are 12 inch Milwaukee bit extensions. The 48-28-4008 is the 12 inch by 3/8 inch version, sized for 3/8 inch bits and compatible driving accessories. The 48-28-4006 is listed as the 12 inch size only. If your bits and holders are 3/8 inch, order the 4008.
2) How much extra reach does the Milwaukee 48-28-40 bit extension add?
A full 12 inches of overall length sits between the tool chuck and the bit, which is what gets a driver down into a recessed fastener in cabinetry, framing, or an equipment housing without switching to a long-reach tool.
3) Do I need a separate long-reach tool for deep-set fasteners, or will an extension work?
For occasional deep-access work, an extension is the cheaper route. The Milwaukee 48-28-40 series is a 12 inch add-on that keeps the driver or drill you already own in hand instead of buying a dedicated long-reach tool. If deep driving is constant production work, a purpose-built tool is the better fit; for recessed cabinet, millwork, and enclosure fasteners that come up now and then, the extension handles it.
4) Will a 12 inch Milwaukee bit extension hold up to impact driving on the jobsite?
The extension is steel built and carries torque and rotation straight through from the tool to the bit, so driving performance stays consistent at full extension. It is a Milwaukee jobsite accessory meant to be dropped in a bag alongside standard driver bits.
5) What kind of jobs is the Milwaukee 12 inch bit extension used for?
Driving fasteners that sit below the surface or behind an obstruction: cabinetry, millwork and furniture assembly, framing, confined-space drilling and driving, remodel and renovation work, and equipment or enclosure assembly where the fastener head is recessed.
6) Where is the Milwaukee 48-28-4008 bit extension made?
Country of origin is China. It is a steel extension, 12 inches long.
