Drill bit Dedra WDD30230 — diameter 30 mm, length 230 mm, for wood, 1 pc

Dedra WDD30230 is a single woodworking drill bit with a 30 mm cutting diameter and a total length of 230 mm. Designed for use with standard electric drills and drill drivers, this bit enables making clean large-diameter holes in wood, timber and composite wooden materials. Supplied as one piece, the tool is intended for carpentry, joinery and DIY tasks where a precise, deep hole is required.

Advantages

The 30 mm diameter provides a wide bore suitable for passages, dowel or pipe clearances. A 230 mm length allows drilling through thicker panels and beams in a single pass, reducing the need for extensions or multiple operations. The bit’s tip geometry and cutting edges are optimized for efficient wood removal and stable tracking in the workpiece, helping to deliver cleaner hole walls and reduced tear-out when used at appropriate speeds.

Suitable for

• Drilling large holes for dowels, bushings or conduit in wooden panels
• Creating passages through beams and joists
• Carpentry and joinery tasks requiring deep, accurate holes
• DIY projects involving furniture making or timber assembly

Key specifications

• Cutting diameter: 30 mm
• Total length: 230 mm
• Material compatibility: wood and wood-based composites
• Package quantity: 1 piece

How to use

Secure the drill bit in the chuck of a compatible electric drill or drill driver, ensuring firm clamping and correct alignment. Mark the drilling point on the wood, apply steady pressure and use a suitable drill speed for the material thickness. Start at a moderate speed to establish the hole, then increase speed as needed while maintaining control. Withdraw the bit periodically on deep holes to clear chips and prevent clogging, and finish the hole with light passes for cleaner edges.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Select drill speed and feed pressure suitable for the wood species and thickness. For precise depth control, use a depth stop or mark the bit. Keep the cutting edges sharp and clear of debris; replace the bit if worn or damaged to maintain hole quality.
