Auger drill bit DeWalt DT4612-QZ, length 200 mm, 1 pcs

DeWalt DT4612-QZ auger drill bit, 200 mm length, is designed for drilling deep, clean holes in wood and similar materials. The screw point provides steady self-feed while the helical LEWIS-style flute efficiently removes chips, enabling continuous forward progress. Peripheral cutting edges reduce splintering at the hole perimeter and produce a neater finish suitable for joinery and through-holes.

Advantages

This auger bit offers fast, precise drilling thanks to its self-feed spur and spiral groove geometry. The dual cutting edge maintains cutting performance when encountering embedded fasteners and helps preserve hole quality. Manufactured from hardened alloy steel, the bit provides extended service life under typical woodworking and site conditions.

Suitable for

• Drilling deep holes in soft and hardwoods
• Through-holes for bolts, dowels and wiring
• Carpentry and framing tasks on construction sites
• Joinery and furniture making requiring clean hole edges

How to use

Select an appropriate drill or brace that accepts the bit shank, secure the workpiece, and mark the drilling position. Start drilling at low speed to engage the screw point, then apply steady pressure while allowing the spiral flute to evacuate chips. Maintain perpendicular alignment for straight holes; retract periodically in deep cuts to clear chips if necessary. Use appropriate personal protective equipment and clamp the workpiece to avoid movement.

Usage recommendations

For best results use in wood and wood-based materials. When drilling near edges or finished surfaces, back the workpiece or use sacrificial backing to minimize blowout. Avoid excessive side load and overheating; if the bit encounters metal fasteners, run the drill at moderate speed and withdraw to clear chips.
