DeWalt Auger Drill Bit DT4634-QZ — 1 pc, right-hand rotation

DeWalt Auger Drill Bit DT4634-QZ is a single right-hand rotation auger bit designed for efficient wood boring and construction site drilling. Manufactured from hardened alloy steel with heat treatment and tempering, the bit combines a self-feed spur, dual cutting edges and a hollow center flute to deliver fast penetration, effective chip extraction and improved wear resistance during repetitive use. Supplied as a single piece in a polybag with a hanging hole, this auger bit is a direct accessory for compatible drills that require a hex shank and a long-reach bit for deep-hole drilling in wood and similar materials.

Advantages

The hardened alloy steel construction and heat-treated, tempered finish increase durability and resistance to wear. A self-feed spur ensures steady, controlled entry and faster cutting without forced feed, while the dual cutting edge improves performance when encountering embedded nails or denser grain. The hollow center flute provides aggressive chip removal to reduce clogging and maintain cutting efficiency over long bores. The hex shank offers secure seating in compatible chucks and quick bit changes.

Suitable for

• Boring deep clean holes in timber and construction lumber
• Installing through-bolts, dowels or running cables through wooden members
• Replacement or accessory use with compatible drills for contractor and carpentry tasks

How to use

Install the auger bit into a compatible drill or driver with a matching hex chuck, ensuring the bit is tightened securely. Position the self-feed spur at the starting point on the wood surface to centre the bit and apply steady pressure; the spur will draw the bit into the material while the dual cutting edges remove material. Run the drill at an appropriate speed for the timber species and diameter; maintain firm control to keep the hole straight. Withdraw the bit periodically on very deep holes to clear chips and prevent binding.

Usage recommendations

Use appropriate drill speeds and steady feed pressure for clean holes; slow drilling in hardwoods and higher speeds in softwoods helps control heat and prolong bit life. Wear eye and hand protection when drilling and inspect the workpiece for embedded metal before drilling. For best results, clear chips regularly and avoid side loading to preserve the bit’s cutting edges.
