Auger drill bit DeWalt DT4608, 200 mm length, single piece

DeWalt DT4608 auger drill bit, 200 mm length, supplied as a single piece. Designed for drilling clean, deep holes in wood and timber, this auger bit features a self-feed spur and a threaded tip that ensures efficient feed into the material and reliable chip removal. The spiral groove shape provides continuous chip evacuation while peripheral cutting reduces spalling for neat bore edges. The bit is suitable for use with handheld and bench drills in carpentry, woodworking and construction where accurate, fast wood boring is required.

Advantages

The DeWalt auger bit combines a self-feed spur for rapid penetration with a spiral groove that maximises chip transport and drilling progress. Peripheral cutting produces clean hole edges with minimal splintering. Hardened alloy steel construction and dual cutting edges increase wear resistance and maintain cutting performance even when encountering embedded nails or dense timber.

Suitable for

• Through and blind holes in soft and hard woods
• Carpentry and framing work
• Door and window installation requiring precise bore alignment
• General woodworking, bench drilling and portable drill applications

Key specifications

• Overall length: 200 mm
• Type: single-piece auger bit for wood
• Tip: threaded self-feed tip for automatic advance
• Flute design: spiral groove for continuous chip removal
• Cutting: peripheral cutting edge for reduced spalling
• Material: hardened alloy steel with dual cutting edges for improved durability

How to use

Secure the auger bit in the drill chuck, ensuring concentric alignment and proper tightening. For handheld drilling, support the workpiece and keep the drill perpendicular to the surface to ensure straight holes. Start drilling at low speed to allow the threaded tip to engage, then increase speed as the bit advances; maintain steady pressure without forcing the bit. Clear chips periodically on deep holes by retracting the bit slightly to allow evacuation, or use a drill with reverse to help remove accumulated material. When drilling near fasteners or metal, proceed cautiously to avoid damage to the bit or workpiece.

Usage recommendations

Use appropriate personal protective equipment (eye and hearing protection and gloves) and clamp workpieces for stable operation. Match drill speed and feed pressure to the wood species: slower speeds for hard woods and higher speeds for soft woods for best hole quality and extended bit life.
