Drill bit Dedra WDA30152 — diameter 30 mm, length 152 mm, for wood, 1 pc

Dedra WDA30152 is a single-piece wood drill bit with a 30 mm diameter and a working length of 152 mm. Designed for use with standard handheld and bench drills, this bit is intended to create clean, large-diameter holes in a variety of wooden materials. The geometry of the cutting tip and flutes helps to evacuate chips efficiently while maintaining hole accuracy for carpentry, furniture making and general woodworking tasks.

Advantages

The 30 mm diameter provides a uniform, round hole suitable for dowels, pipe pass-throughs or large fasteners without the need for multiple smaller pilot holes. Its 152 mm length reaches deeper workpieces and allows for through-holes in moderately thick boards. The single-piece construction ensures stable cutting action and reduces the risk of breakage under typical wood-drilling conditions. Compatibility with standard drill chucks makes it easy to install and use on a wide range of drills.

Suitable for

• Carpentry and joinery — drilling holes for dowels and fittings
• Furniture making — creating openings for connectors and cable routing
• General woodworking — through-holes in boards, panels and beams
• Installation tasks — making entry points for pipes or large fasteners

Key specifications

• Diameter: 30 mm
• Overall length: 152 mm
• Material compatibility: wood
• Quantity: 1 piece
• Shank type: compatible with standard drill chucks

How to use

Secure the drill bit in a compatible drill chuck, ensuring it is centered and tightened. Mark the drilling position on the wooden workpiece and, if precise depth is required, set a depth stop on the drill or mark the bit. Start drilling at low speed to establish the hole, then increase speed while applying steady, even pressure. Periodically withdraw the bit to clear wood chips and prevent clogging; for through-holes, continue until the bit passes through the material. After use, clean wood debris from the flutes and store the bit in a dry place.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and hearing protection. For harder or laminated woods, reduce feed force and use intermittent drilling to avoid overheating. When precise, clean edges are required, consider using a backing piece to prevent tear-out on exit. Keep the bit sharp and free of resin build-up to maintain performance.
