Description

The DT4608-QZ is a DEWALT 14mm x 200mm (100mm working length) auger wood drill bit featuring the LEWIS spiral groove design for maximum chip transport and high drilling progress through solid timber. Auger bits are the preferred choice for boring deep, clean holes through structural members — beams, joists, posts, and doors — where standard twist or spade bits lack the chip clearance needed at depth.
The threaded pilot point pulls the bit through the material, reducing operator effort and maintaining consistent drilling speed throughout the full working depth. The LEWIS spiral groove shape provides superior chip evacuation compared to standard flute designs, keeping the hole clear and preventing binding. Suitable for deep boring of cable, pipe, and conduit clearance holes in structural timber.
Compatible with corded and cordless drills with 3-jaw chucks. Suitable for electricians, plumbers, and structural carpenters who require deep, accurate holes through solid timber beams, joists, and stud construction. Heat-treated for maximum durability.
