Why this one
Extra reach for recessed screws
A bit holder extension adds length between your hand and the fastener, for screws deep inside assemblies or at the bottom of recessed cavities.
Four lengths
Available in 100, 141, 150 and 238 mm, so you can choose how much reach the job needs.
1/4 inch hex drive
Made for use with 1/4 inch hex bits and a 1/4 inch bits driver, instead of stacking short adapters.
Sold individually
Each extension is sold on its own, to replace a worn piece or fill a gap in a kit you already own.
Read the full description
Some fasteners hide deep inside assemblies, behind panels, or at the bottom of recessed cavities where no standard-length driver can reach. This 238 mm driver extension solves that problem by adding serious reach to your Teng Tools MDR913 mini ratchet system — approximately 9.4 inches of controlled length between your hand and the fastener.
Rather than stacking short adapters or removing surrounding components to gain access, you install a single bar and drive the fastener directly. The result is less time spent on workarounds and more time making progress through your task list.
Sold as an individual piece, this impact bit holder extension is the right purchase when you already own a full kit and simply need one specific length. Whether it is a replacement for a worn piece or an addition that fills a gap in your reach capability, buying a single item keeps your cost and clutter in check.
The 1/4 inch interface works with standard driver bits, letting you pair the extension with whatever bit the task demands. Teng Tools designs its accessories to integrate smoothly with the broader system of hand tools and storage trays, so adding this extension to your setup is as simple as dropping it into the correct slot and heading to the next job.
