## Long description

DeWalt auger drill bit DT4645-QZ, length 380 mm, 1 pc is designed for drilling deep, clean holes in wood and timber. The bit features a self-feed screw tip that ensures steady penetration and a spiral flute geometry that promotes fast chip evacuation. Constructed from hardened alloy steel with dual cutting edges and a self-feed spur, this auger bit is suitable for use in handheld drills and drill presses for carpentry, timber framing and installation tasks where accurate, burr-free holes are required.
Advantages
The self-feed screw tip provides controlled, fast material penetration, reducing the need for excessive pressure from the operator. Dual cutting edges improve cutting performance and durability when encountering embedded nails or dense grain. The hardened alloy steel construction extends bit life under regular site and workshop use, while the spiral "LEWIS" groove shape enhances chip transport to maintain drilling progress and reduce clogging. Peripheral cutting produces clean hole walls with minimal spalling, resulting in neater joinery and easier post-processing.
Suitable for
 Drilling deep holes in soft and hardwoods for bolts, dowels and wiring
 Carpentry and timber framing tasks requiring precise, burr-free holes
 Installation work with handheld drills or drill presses
 Renovation jobs where fast chip removal and reduced clogging are beneficial
Key specifications
 Length: 380 mm overall
 Material: hardened alloy steel
 Tip type: self-feed screw tip for steady penetration
 Flute design: spiral groove (LEWIS) for efficient chip removal
 Cutting edges: dual/peripheral cutting for cleaner holes and reduced spalling
 Supply: single piece
How to use
Secure the auger bit in a compatible drill chuck or appropriate arbor, ensuring tight clamping for coaxial rotation. Position the screw tip at the marked drilling point and start the drill at low speed to engage the self-feed tip, then increase speed as the bit advances while maintaining straight alignment. Allow the screw tip and spiral flute to self-feed and remove chips; withdraw occasionally to clear long chips if necessary. When encountering nails or metal inclusions, reduce speed and steady the tool to avoid damage; inspect the bit for wear after heavy use.
Usage recommendations
Use appropriate eye and hand protection when drilling. Match drill speed and feed pressure to the wood type: lower speeds for hardwoods and higher permissible speeds for softwoods. Keep the bit clean of resin and pitch buildup to maintain cutting efficiency and prolong service life.
