## Summary description

DeWalt DT4638-QZ is an auger drill bit 380 mm long supplied as a single piece. Designed for drilling deep, clean holes in timber and similar materials, it features a screw tip for steady feed and spiral flute for efficient chip removal. Suited for woodworking, joinery and on-site construction tasks requiring longer reach.

## Long description

DeWalt DT4638-QZ auger drill bit, length 380 mm, single piece is designed for drilling deep, clean holes in timber and similar materials where extended reach and controlled feed are required. The bit combines a screw tip that provides steady penetration with a Lewis-style spiral flute for efficient chip removal. Peripheral cutting geometry reduces spalling and produces neat hole edges during through- and blind-hole woodworking operations.
Advantages
The auger bit features a self-feed screw tip for steady, hands-free progress and a dual cutting edge that enhances durability when encountering embedded fasteners. Hardened alloy steel construction extends service life under regular workshop and on-site use. The spiral groove shape maximizes chip transport to maintain cutting speed and reduce clogging, while the peripheral cutting design helps achieve clean hole walls and minimal tear-out.
Suitable for
 Drilling deep or long-reach holes in soft and hardwoods
 Joinery and timber framing tasks requiring precise, clean holes
 On-site construction and renovation where cordless or corded drills are used
 Installing bolts, dowels, and wooden pegs in structural and finish carpentry
Key specifications
 Overall length: 380 mm
 Type: auger (spiral) wood drill bit
 Tip: self-feed screw tip for controlled penetration
 Flute: Lewis-style spiral flute for efficient chip removal
 Cutting geometry: peripheral cutting edge for reduced spalling
 Material: hardened alloy steel for increased durability
 Quantity: single piece
How to use
Secure the DeWalt auger bit in a compatible drill chuck and ensure the screw tip is centered on the intended drilling point. Start drilling at low speed to engage the self-feed tip, then increase speed moderately while maintaining axial pressure. Allow the screw tip to draw the bit into the workpiece while periodically withdrawing to clear chips if drilling deep holes. Use appropriate clamping and support for the workpiece to prevent movement and reduce tear-out at exit points.
Usage recommendations
Use the auger bit with drills that deliver steady torque; for large-diameter or very deep holes consider intermittent withdrawal to remove chips and avoid overheating. Inspect the bit for damage after contact with nails or metal inclusions and replace if cutting edges are compromised.
