Auger drill bit DeWalt DT4614, Length 200 mm, 1 pc

Auger drill bit DeWalt DT4614, Length 200 mm, 1 pc is designed for drilling deep, clean holes in wood and wood-based materials. The bit combines a screw point for controlled self-feeding with a helical flute that efficiently removes chips and reduces clogging during prolonged drilling. Peripheral cutting edges help produce neat hole walls with minimal spalling, making this auger suitable for joinery, timber framing and other woodworking tasks requiring accurate, straight bores.

Advantages

The spiral groove shape provides maximum chip transport and consistent drilling progress, while the self-feed spur ensures precise engagement and reduced walking at the start of the bore. Dual cutting edges increase cutting durability and maintain clean hole edges when encountering occasional nails or hard inclusions. Constructed from hardened alloy steel, the bit delivers extended life under frequent use and preserves sharpness for repeatable performance.

Suitable for

• Drilling deep timber holes for dowels and joinery
• Timber framing and structural carpentry
• Creating clean holes for wiring or pipe passage in wooden elements
• Use with handheld drills and braces where controlled feed is required

Key specifications

• Overall length: 200 mm
• Tip type: screw point for self-feed
• Flute design: helical spiral for efficient chip removal
• Cutting edges: peripheral cutting with dual edges for durability
• Material: hardened alloy steel for extended wear resistance
• Pack quantity: 1 piece

How to use

Mount the auger bit securely in the drill chuck or brace, ensuring the shank is properly seated. Start drilling at low speed to allow the screw point to engage and draw the bit into the material, then increase speed as needed while maintaining steady axial pressure. Withdraw periodically on deep holes to clear chips from the flute and prevent heat buildup. When drilling through laminated or veneered surfaces, support the exit side to reduce tear-out and achieve cleaner hole edges.

Usage recommendations

Use appropriate personal protective equipment, select a drill speed suitable for the timber species, and avoid excessive lateral force to maintain bit life and hole accuracy. For repeated or heavy-duty work, inspect the cutting edges regularly and replace the bit if worn or damaged.
