Drill bit Dedra WDD20460 — diameter 20 mm, length 460 mm, for wood, 1 pc

Dedra WDD20460 is a single wood drill bit with a 20 mm diameter and an overall length of 460 mm. It is intended for drilling through timber and other wooden materials, offering an extended shank to reach deeper positions. Supplied as one piece, the bit is compatible with drills that accept long-shank woodworking bits and can be used in carpentry, joinery and general woodworking tasks.

Advantages

The 20 mm cutting diameter and long 460 mm length enable deeper boreholes without the need for extensions. A single-piece supply simplifies selection and replacement. The geometry is optimized for drilling in wood, producing clean chips and reducing tear-out when used at appropriate speeds. The long shank improves reach in confined or recessed areas and suits most standard drill chucks that accept long bits.

Suitable for

• Creating deep holes in structural timber and beams
• Drilling for dowels, bolts, and through-holes in furniture making
• Reaching recessed or hard-to-access drilling points in joinery
• General woodworking tasks requiring a 20 mm bore

Key specifications

• Cutting diameter: 20 mm
• Overall length: 460 mm
• Material compatibility: wood and wooden composites
• Quantity: 1 piece

How to use

Install the Dedra WDD20460 into a drill whose chuck can accept the shank diameter and length. Secure the bit firmly and set an appropriate rotational speed for wood drilling to avoid burning or splintering — moderate to high speeds are typical depending on timber density. Use steady feed pressure and, where possible, support the workpiece to reduce vibration. Withdraw the bit periodically on very deep holes to clear chips and prevent clogging.

Usage recommendations

Use appropriate personal protective equipment, such as safety glasses and hearing protection. For precise depth control, combine the bit with a depth stop or mark the required depth on the shank. When drilling hardwoods or laminated materials, consider pilot drilling or reducing speed to maintain hole quality.
