Drill bit Dedra WDB05085, 5 mm diameter, 85 mm length, for wood, 1 pc

Dedra WDB05085 wood drill bit, 5 mm diameter and 85 mm overall length, is designed for drilling precise holes in solid wood and wood-based materials. Supplied as a single piece, this long, slim bit fits standard chucks and is intended for through-holes and controlled depth drilling in carpentry, furniture assembly and general DIY tasks. Its geometry focuses on clean chip evacuation and reduced splintering at entry and exit points.

Advantages

The 5 mm diameter and extended 85 mm length allow access to deeper drilling positions without repositioning the workpiece. The bit’s tip and flute profile provide consistent cutting performance in wood, helping to produce straight, accurate holes with minimal tear-out. As a single-piece item, it is convenient to carry as a spare or to use for one-off tasks where a long, narrow hole is required.

Suitable for

• Drilling through solid wood and plywood
• Furniture assembly and dowel hole preparation
• Carpentry tasks requiring deep narrow holes
• DIY projects and repairs where precise small-diameter holes are needed

Key specifications

• Diameter: 5 mm
• Overall length: 85 mm
• Material compatibility: wood and wood-based materials
• Quantity: 1 piece
• Shank type: compatible with standard drill chucks

How to use

Secure the Dedra WDB05085 drill bit in a standard keyed or keyless chuck, ensuring it is clamped firmly and centered. Mark the drilling point on the workpiece and, if necessary, use a pilot mark or center punch to prevent walking. Start drilling at low to moderate speed to establish the hole, then increase speed as appropriate for the wood type and thickness. Use steady pressure and allow the bit to clear chips frequently to avoid clogging and overheating. For through-holes, support the exit side with sacrificial backing to minimize splintering.

Usage recommendations

For best results, match drill speed to the wood density: lower speeds for hardwoods and higher speeds for softwoods. Keep the bit sharp and free of resin buildup; clean with a suitable solvent if necessary. When drilling multiple holes, periodically withdraw the bit to remove chips and reduce heat. Wear eye and hearing protection while drilling and secure small workpieces with clamps to maintain accuracy.
