Drill bit Dedra WDD25460 — 2.5 cm diameter, 460 mm length, for wood, 1 pc

Dedra WDD25460 is a single wood drill bit with a 2.5 cm diameter and a 460 mm overall length, designed for drilling deep holes in solid and laminated wood. The bit is intended as a replacement or extension for hand-held and stationary drills that accept its shank, providing extended reach for tasks such as drilling through beams, creating deep dowel holes, or preparing long boring runs where a larger diameter is required.

Advantages

The Dedra WDD25460 combines a large 25 mm cutting diameter with an extended 460 mm length to reach areas not accessible with standard bits. Its geometry is optimized for wood to offer stable cutting and efficient chip evacuation over long depths. Supplied as a single piece, it is simple to fit and replace in compatible drill chucks, enabling use in both portable and fixed drilling setups.

Suitable for

• Deep-hole drilling in solid timber and laminated wood
• Drilling long dowel or pin holes in joinery and furniture making
• Boring through beams, posts and structural members
• Situations requiring extended reach where standard-length bits are insufficient

Key specifications

• Cutting diameter: 2.5 cm (25 mm)
• Overall length: 460 mm
• Material suitability: wood (solid and laminated)
• Quantity: 1 piece

How to use

Fit the Dedra WDD25460 into a drill chuck that securely accepts the bit's shank and ensure the chuck is tightened according to the drill manufacturer's instructions. Use appropriate drill speeds for wood to avoid burning or excessive vibration; lower speeds are recommended for larger diameters. Support the workpiece firmly and, when drilling deep holes, retract the bit periodically to clear chips and prevent clogging. Apply steady, even pressure—do not force the bit—and finish the hole with light feeding to maintain a clean edge.

Usage recommendations

For best performance, use the bit with drills that offer sufficient torque at moderate speeds, clamp the workpiece securely, and clear chips frequently during long cuts. Inspect the bit before use and replace it if the cutting edges are worn or damaged to maintain drilling quality and safety.
