Drill bit Dedra WDD18230 — 1.8 cm diameter, 230 mm length, for wood, 1 pc

Dedra WDD18230 is a single wood drill bit with a 1.8 cm diameter and a 230 mm overall length. Designed specifically for drilling in wood, this bit offers extended reach for drilling deeper holes in beams, boards, and other wooden components. It is supplied as one piece and is compatible with handheld drills and drill presses that accept standard shank sizes for larger-diameter wood bits.

Advantages

The 1.8 cm cutting diameter and long 230 mm length provide greater reach and allow drilling through thick timber or multiple stacked boards in a single pass. The bit is optimized for wood, which helps deliver clean, efficient cuts and reduces tear-out when used at appropriate speeds. Supplied as a single unit, it is convenient for occasional or professional tasks where a larger wood bore is required.

Suitable for

• Making through-holes in timber beams and planks
• Drilling long holes for dowels, rods or wiring passages in wooden structures
• Carpentry and joinery tasks requiring larger diameter holes
• Installation jobs where a long-reach wood bit is needed

Key specifications

• Cutting diameter: 1.8 cm
• Overall length: 230 mm
• Material suitability: Wood
• Quantity in pack: 1 piece
• Intended use: Handheld drills and drill presses compatible with wood bits

How to use

Secure the Dedra WDD18230 in the drill chuck and ensure the shank is tightened. Mark the drilling point on the wood and, if necessary, clamp the workpiece to prevent movement. Start drilling at low to medium speed to establish the hole, then increase speed as appropriate for the wood species and thickness. Apply steady, even pressure without forcing the bit; allow the bit to remove chips and clear them regularly to maintain cutting efficiency. For deep holes, periodically withdraw the bit to clear chips and reduce friction.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Match drilling speed to the wood type—softer woods generally allow higher speeds, while hardwoods require lower speeds and steady feed. Keep the bit sharp and clean; if excessive heat or burning occurs, reduce speed or take breaks to prevent damage to the bit and workpiece.
