Drill bit Dedra WDD25230 — diameter 25 mm, length 230 mm, for wood, 1 pc

Dedra WDD25230 drill bit with a 25 mm diameter and 230 mm overall length is designed specifically for woodworking. The single-piece bit features a shank and flute geometry optimised for drilling into timber and similar materials, allowing the creation of deeper, wider holes for through-holes, dowel seats or cable passages. Supplied as one unit, it fits standard drill chucks compatible with this shank style.

Advantages

The 25 mm diameter provides a consistent, clean hole profile while the 230 mm length reaches well into thicker workpieces without the need for extensions. The flute design facilitates efficient chip evacuation during cutting in wood, reducing clogging and heat build-up. The shank is sized for secure gripping in common drill chucks, improving stability and concentricity during operation.

Suitable for

• Drilling through timber for dowels and joinery
• Creating larger-diameter holes for cable routing in furniture
• Carpentry and joinery where deep, clean holes are required
• General woodworking repairs and installations

Key specifications

• Diameter: 25 mm
• Overall length: 230 mm
• Material suitability: wood and similar timber-based materials
• Package quantity: 1 piece

How to use

Secure the drill bit in a compatible drill chuck, ensuring it is tightened and concentric. Mark the drilling position on the workpiece and, if depth control is required, set a depth stop on the bit or use a collar. Start drilling at low to moderate speed to establish the cut, then increase speed as appropriate for the wood type while applying steady, even pressure. Withdraw the bit periodically to clear chips if drilling deep holes, and finish by backing out the bit while the drill is running at low speed to avoid tear-out.

Usage recommendations

Use appropriate personal protective equipment, clamp the workpiece securely, and select drill speeds suitable for the wood species to extend bit life and maintain hole quality. If drilling hardwood or abrasive materials, consider light lubrication or reduced feed pressure and inspect the cutting edges regularly for wear.
