Drill bit Dedra WDA20152 — 2 cm diameter, 152 mm length, for wood, 1 pc

Dedra WDA20152 drill bit is a single woodworking bit with a 20 mm (2 cm) diameter and 152 mm overall length, designed for drilling clean holes in wood and similar soft materials. Supplied as one piece, this bit fits common manual and power drills with compatible chucks and is intended for straightforward carpentry and furniture assembly tasks where a larger-diameter wood hole is required.

Advantages

The 20 mm cutting diameter provides a wide, stable bore suitable for dowels, large fasteners or cable passages in wooden components. The 152 mm overall length gives adequate reach through thicker boards or when working with stacked material. Compatibility with standard drill chucks makes the bit versatile for both handheld and bench-mounted drilling tools. The single-piece supply allows precise replacement or use as a spare when larger wood holes are needed.

Suitable for

• Drilling holes for dowels and large wooden plugs
• Furniture assembly and cabinet making
• General carpentry and joinery tasks in softwood and hardwood
• Creating passages for cables or pipes through wooden panels

How to use

Secure the Dedra WDA20152 drill bit in the drill chuck and tighten it according to the drill manufacturer’s instructions. Mark the drilling position on the workpiece and, if precision is required, use a centre punch or pilot mark. Start drilling at low speed to establish the hole, then increase speed as appropriate for the wood type while applying steady, even pressure. For through-holes, support the workpiece to prevent splintering at the exit side; for clean edges, consider backing the workpiece with sacrificial wood. Withdraw the bit periodically to clear chips when drilling deep holes.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Match drilling speed to wood density—lower speeds for hardwoods and higher speeds for softwoods—and avoid excessive feed force that can cause burning or bit damage. Keep the bit clean of resin build-up and store it dry to maintain cutting performance.
