Auger drill bit DeWalt DT4604-QZ — 1 pc, right-hand rotation

DeWalt DT4604-QZ auger drill bit is a single-piece spiral bit engineered for right-hand rotation and efficient wood drilling. Made from hardened alloy steel with heat treatment and tempering, this auger bit combines a self-feed spur, dual-cutting edge and a hollow centre flute to accelerate penetration, improve chip extraction and maintain cutting performance when encountering knots or embedded nails. Supplied as one piece in a polybag with a hanging hole, it is intended for woodworking and general-purpose drilling tasks where an auger profile produces cleaner, deeper holes.

Advantages

The hardened alloy steel construction and heat-treated tempering extend service life and resist wear during repeated use. A dual-cutting edge increases durability against nails and hard sections in wood, while the self-feed spur ensures faster, more accurate starts and stable tracking. The hollow centre flute rapidly evacuates chips to reduce clogging and improve hole quality, enabling consistent drilling depth and cleaner exits.

Suitable for

• Through-holes and deep holes in soft and hardwoods
• General woodworking and carpentry tasks
• Drilling where improved chip extraction is required
• Applications where right-hand rotation drills are used

How to use

Mount the DeWalt DT4604-QZ auger bit in a compatible drill with a suitable chuck, ensuring secure clamping. Position the self-feed spur on the intended mark and start drilling at low speed to allow the spur to engage and the bit to self-feed. Increase speed as needed while maintaining steady pressure; allow the hollow flute to evacuate chips naturally and periodically withdraw the bit for cleaning when drilling deep holes. Follow the drill manufacturer’s recommendations for speed and torque for the material and drill in use.

Usage recommendations

Use protective eyewear and hearing protection when drilling. For best results in hardwood or when encountering nails, reduce speed and apply firm, controlled pressure. Clean the flute regularly during prolonged drilling to maintain chip evacuation and inspect the bit for wear before each use.
