Auger drill bit DeWalt DT4602 — 200 mm length, single piece

DeWalt DT4602 auger drill bit, 200 mm length, single piece, is designed for drilling deep, clean holes in wood and wood-based materials with hand or power drills. The auger geometry features a Lewis-style spiral flute for effective chip evacuation and steady forward progress. Peripheral cutting edges reduce spalling at the hole entrance and produce smooth, accurate bore walls suitable for joinery, carpentry and on-site construction tasks.

Advantages

The spiraled flute geometry maximizes chip transport to maintain drilling speed and prevent clogging. A dedicated peripheral cutting design provides clean hole entry and minimal splintering. The single-piece construction ensures stable cutting action and consistent hole diameter during use. Compatibility with standard drill chucks allows use with a wide range of hand and electric drills for flexible on-site and workshop applications.

Suitable for

• Drilling deep holes in solid wood and laminated panels
• Joinery and dowel hole preparation
• Carpentry and framing work on-site
• Furniture assembly and repair

Key specifications

• Overall length: 200 mm
• Design: auger/spiral flute with Lewis-style geometry
• Cutting type: peripheral cutting edges for reduced spalling
• Material compatibility: solid wood, softwood, hardwood, wood-based panels
• Packaging: single piece

How to use

Mount the auger bit securely in a compatible drill chuck and set the drill to an appropriate rotation speed for wood drilling. Align the point of the bit with the marked drilling position and apply steady axial pressure while allowing the spiraled flute to evacuate chips. Withdraw periodically on deep holes to clear chips if needed. Ensure a firm grip on the workpiece or clamp it to prevent movement and maintain drill stability for accurate bore alignment.

Usage recommendations

Use moderate drill speeds for hardwoods and higher speeds for softwoods; apply consistent pressure without forcing the bit to extend tool life. Keep the flute clear of debris during prolonged drilling and inspect the cutting edge for wear; replace the bit if it no longer produces clean holes.
