Drill bit AWTools AW40369 spiral wood cylindrical 14 mm

Spiral cylindrical wood drill bit AWTools AW40369 14 mm is designed for drilling precise round holes in soft and hard wood. The spiral flute geometry promotes efficient chip evacuation, reducing clogging and heat build-up during continuous work. The cylindrical shank provides secure mounting in standard chucks and drill drivers, making this 14 mm wood drill bit suitable for workshop and on-site applications that require consistent hole quality.

Advantages

The spiral design delivers smooth cutting action and helps remove chips quickly from the hole, improving drilling speed and finish. The cylindrical shank ensures stable holding in chucks and reduces runout, supporting accurate hole position and diameter. Hardened cutting edges maintain sharpness for longer life when used on timber, boards and laminated panels. The straight, round hole produced by this bit is suitable for dowels, fittings and through-holes without additional reaming.

Suitable for

• Drilling 14 mm holes in solid wood and soft hardwoods
• Creating dowel holes during furniture assembly
• On-site repair and fitting work where consistent 14 mm holes are required
• Drilling in laminated panels, plywood and chipboard with careful feed

Key specifications

• Cutting diameter: 14 mm
• Material: high-speed steel cutting section with hardened edge (as typical for this type)
• Flute type: spiral flute for chip evacuation
• Shank type: cylindrical shank for standard drill chucks
• Intended material: soft and hard wood, laminated panels and similar wood-based materials

How to use

Clamp the workpiece securely to prevent movement and select an appropriate drill speed for the wood species—lower speeds for hard woods and higher speeds for softwoods. Insert the cylindrical shank of the bit into the drill chuck and tighten firmly. Start drilling with steady, even pressure; allow the spiral flute to clear chips by periodically withdrawing the bit on deep holes. For clean exit holes in thin panels, support the back side of the workpiece or finish the hole from both sides.

Usage recommendations

Use cutting lubricant only when appropriate for the material and avoid excessive side forces to prolong bit life. Keep the bit sharp and inspect for wear before precise tasks—replace if the cutting edges show significant dulling or chipping.
