Freud DHS375XT18 Universal Drill Extension 18x3/8 Inch

Product Description

The FREUD DHS375XT18 is an 18-inch universal drill extension with a 3/8-inch shank, designed to extend reach into confined or hard-to-access areas during drilling and hole saw operations. The extension features a tool-free attachment system, allowing accessories to be connected and swapped without wrenches or additional hardware. A quick-change mechanism lets technicians switch between accessories without interrupting workflow. At 2.85 pounds, the unit ships in a package of 3. This extension is suited for electricians, plumbers, HVAC installers, and general contractors who regularly drill through deep wall cavities, floor joists, or structural members where standard-length drivers fall short.

The DHS375XT18 is intended for use in residential and light commercial construction and renovation work. It is particularly well-suited for any application requiring extended reach, including running conduit, pipe penetrations, or HVAC duct openings through structural framing. The extension is specifically noted as compatible with the Diablo Snap Lock Plus Hole Saw Mandrel system, making it a natural add-on for trades already using that mandrel platform. It is appropriate for use with standard 3/8-inch drive drill chucks.
