Description

The DT4646-QZ is a DEWALT 24mm x 840mm extra-long auger wood drill bit for deep boring applications in structural timber where exceptional reach is required — such as drilling through multiple floor joists or stud bays in a single pass, or accessing deeply located structural members from a distance.
The LEWIS spiral groove design provides maximum chip transport and consistent drilling speed throughout the full 840mm length. The threaded pilot point pulls the bit through material efficiently, reducing the effort required to maintain progress at depth in dense hardwood or laminated structural timber.
Compatible with heavy-duty corded drills and powerful cordless drills with 3-jaw chucks. Suitable for structural carpenters, electricians, and plumbers who require deep, through-structural boring capability in timber frame and heavy timber construction.
