Drill bit Dedra WDD08460 — 8 mm diameter, 460 mm length, for wood, 1 pc

Dedra WDD08460 drill bit is a single-piece 8 mm diameter, 460 mm overall length bit designed specifically for drilling wood. It provides extended reach for through-holes and deep drilling tasks and is compatible with standard chucks. The geometry and length make it suitable for carpentry and joinery operations where access into recessed or deep workpieces is required.

Advantages

The long 460 mm length allows drilling at depths and through sections that standard bits cannot reach, while the 8 mm diameter provides a balance between strength and minimal material removal. As a single-piece bit, it offers consistent concentricity and reduced risk of wobble in standard chucks. Its design is focused on wood applications which helps maintain cleaner holes and reliable chip evacuation when used with appropriate feed rates.

Suitable for

• Carpentry and joinery tasks requiring deep or hard-to-reach holes
• Door and window frame installation where extended reach is needed
• General woodworking projects such as shelving, furniture assembly, and timber framing
• Through-holes in panels and stacked timber where long reach is required

Key specifications

• Diameter: 8 mm
• Overall length: 460 mm
• Material suitability: wood
• Quantity: 1 piece

How to use

Install the Dedra WDD08460 drill bit in a compatible drill or driver with a standard chuck, ensuring the bit is securely clamped to minimize runout. Begin drilling at low to medium speed to establish the hole and then increase speed as appropriate for the wood type. Use steady, moderate feed pressure and periodically withdraw the bit to clear chips when drilling deep holes. Secure the workpiece to prevent movement and wear appropriate eye protection.

Usage recommendations

For best results, match drill speed to the wood species (lower speeds for hardwoods, higher for softwoods), keep the bit straight to avoid binding, and clear chips frequently during deep drilling. If drilling laminated or veneered panels, consider backing the workpiece to reduce tear-out at the exit side.
