Drill bit Dedra WDD08230 — 8 mm diameter, 230 mm length, for wood, 1 pc

Dedra WDD08230 — 8 mm diameter, 230 mm length drill bit designed for drilling wood. This single-piece bit is intended for through-holes and deep bore tasks in construction, carpentry and furniture work. The solid shank provides stable guidance in both handheld and stationary drills, while the spiral flute geometry assists in effective chip removal to maintain drilling speed and reduce clogging.

Advantages

The drill bit combines a long working length with a standard 8 mm diameter to reach deep into wooden elements without sacrificing shaft stability. Its spiral flute design improves chip evacuation, helping to prevent overheating and binding during continuous drilling. A solid shank ensures compatibility with common chucks and stable rotation, contributing to precise, straight holes in soft and hard wood species.

Suitable for

• Drilling through-holes in beams, planks and panels
• Deep bore holes for dowels and fasteners in furniture assembly
• Carpentry tasks requiring extended reach
• Work with handheld drills and drill presses

Key specifications

• Diameter: 8 mm
• Overall length: 230 mm
• Intended material: wood
• Piece count: 1
• Shank type: solid straight shank for standard chucks
• Flute type: spiral flute for chip evacuation

How to use

Secure the Dedra WDD08230 drill bit in a compatible drill chuck and tighten firmly. Mark the drilling point and, when necessary, use a center punch or pilot guide to prevent skidding. Start drilling at low speed to establish the cut, then increase speed as appropriate for the wood type. Apply steady, moderate pressure and periodically withdraw the bit to clear chips from the flute when drilling deep holes. Reduce speed and pressure near breakthrough to avoid splintering at the exit side.

Usage recommendations

Use appropriate personal protective equipment, such as safety glasses and hearing protection. For clean exit holes, support the workpiece at the exit side or use backing board. For prolonged drilling sessions, periodically retract the bit to remove chips and allow cooling. Match drill speed settings to the wood hardness—lower RPM for hardwoods and higher RPM for softwoods.
