Drill bit Dedra WDD22230 — 2.2 cm diameter, 230 mm length, for wood, 1 pc

Dedra WDD22230 is a single wood drill bit with a 2.2 cm diameter and total length of 230 mm, designed for use with standard drill chucks. The bit is intended for creating deep, accurate holes in solid timber, wooden panels and composite wood products. Supplied as one piece, it is suitable for routine carpentry, furniture assembly and repair tasks that require a robust, straight hole up to the specified depth.

Advantages

The 2.2 cm cutting diameter and 230 mm overall length allow for drilling deeper holes than short bits while keeping a stable runout when used in a properly aligned drill chuck. Designed specifically for wood, the geometry and cutting edges provide effective chip removal and reduced splintering on entry and exit surfaces. Compatibility with common drill chucks makes it easy to fit to corded and cordless drills without additional adapters.

Suitable for

• Creating deep through-holes or blind holes in solid wood and laminated panels
• Furniture assembly, dowel and bolt hole preparation
• Carpentry tasks such as framing, fitting and on-site repairs

Key specifications

• Cutting diameter: 2.2 cm
• Total length: 230 mm
• Material compatibility: wood and wood-based panels
• Package quantity: 1 piece

How to use

Secure the drill bit in a suitable drill chuck and tighten according to the drill manufacturer's instructions. Mark the drilling position and, if required, use a center punch or starter point to prevent walking. Drill at an appropriate speed for the wood type, using steady pressure and clearing chips periodically to avoid clogging. For through-holes, support the workpiece on a sacrificial board to reduce splintering at the exit side.

Usage recommendations

For best results, select drilling speeds based on the wood species: slower speeds for hardwoods and moderate to higher speeds for softwoods. Use appropriate personal protective equipment such as eye protection and gloves, and secure the workpiece before drilling. Inspect the bit for wear before use and replace when cutting edges are dull to maintain hole quality.
