## Summary description

DeWalt DT4649-QZ auger drill bit with 28 mm (2.8 cm) diameter and 380 mm length.

Suitable for carpentry, construction, and installation tasks requiring long, precise boreholes.

## Long description

DeWalt DT4649-QZ auger drill bit with a 28 mm cutting diameter and 380 mm overall length is built for creating deep, precise holes in wood and similar materials. The single-piece construction and screw-tip geometry provide efficient penetration, continuous chip evacuation and stable guidance when used with hand or cordless drills. This auger bit is suitable for tasks that require clean, straight bores such as carpentry joinery, timber framing and installation of through-holes for cables or pipes.
Advantages
The auger design evacuates chips quickly to reduce friction and prevent clogging during extended drilling. A screw-type tip ensures fast self-feeding into the material and maintains centring without pre-punching. The long 380 mm length gives access to deep workpieces while the robust single-piece construction improves durability and resists bending under load. The 28 mm diameter provides a widely used hole size for structural dowels, pipe pass-throughs and larger fasteners.
Suitable for
Drilling deep through-holes in solid wood and timber
Carpentry and joinery tasks requiring straight, clean bores
Timber framing and structural installations
Making holes for cable runs, conduit or plumbing in wooden elements
Use with hand-held or cordless drills where extended reach is needed
Key specifications
Cutting diameter: 28 mm
Overall length: 380 mm
Type: single-piece auger drill bit with screw tip
Material compatibility: wood and wood-based materials
Chip evacuation: auger flute for continuous removal
Intended use: manual and cordless drill operation
How to use
Secure the auger bit in the drill chuck according to the drill manufacturer’s instructions, ensuring it is clamped straight and firmly. Position the screw tip at the start point and apply steady axial pressure while running the drill at an appropriate speed for wood; allow the screw tip to pull the bit into the workpiece without excessive force. Maintain control of the drill to keep the hole straight and withdraw periodically if chip buildup occurs. After drilling, clear remaining chips from the flute and inspect the hole for required fit and finish.
Usage recommendations
For best results, use appropriate drill speeds for the timber species and condition, wear eye protection, and clamp or secure the workpiece. When drilling long holes, periodically retract the bit to clear chips and avoid overheating. If precise entry is critical, consider a pilot mark or starting guide to prevent wander of the screw tip.
