Drill Bit Luna 203380407 20 mm wood paddle cylindrical

Luna 203380407 is a 20 mm paddle-type cylindrical drill bit designed specifically for drilling wood. The flat paddle profile provides efficient wood removal and smooth chip ejection, while the cylindrical shank ensures secure clamping in both handheld and stationary drills. This 20 mm wood paddle bit is suitable for making clean holes for dowels, fittings, cable pass-throughs and other common joinery or installation tasks in soft and hardwoods.

Advantages

The paddle design offers fast cutting and efficient chip evacuation, reducing clogging during prolonged use. A straight cylindrical shank provides stable mounting and compatibility with standard drill chucks. The geometry of the cutting edges and the flat blade help produce relatively clean hole walls and consistent hole diameter in wood materials. The bit is versatile for use in hand drills and drill presses where a 20 mm hole is required.

Suitable for

• Drilling holes for wooden dowels and joinery
• Creating passages for cables and pipes in wooden panels
• Installing fittings, door hardware and furniture assembly
• Rapid rough-boring in softwoods and many hardwoods

Key specifications

• Cutting diameter: 20 mm
• Type: paddle (spade) bit with flat blade profile
• Shank form: cylindrical straight shank for standard chucks
• Material compatibility: designed for use in softwood and hardwood
• Typical applications: through holes, clearance holes and rough-boring in wood

How to use

Secure the shank of the paddle drill bit in the drill chuck and tighten firmly. Mark the drilling position on the wood and, if necessary, use a pilot punch or center point to reduce wandering. Start drilling at low speed to establish the cut, then increase speed moderately while maintaining steady pressure. Withdraw the bit occasionally to clear chips if drilling deep holes. For through-holes, support the workpiece to avoid splintering on the exit side.

Usage recommendations

Use appropriate drill speeds for the wood species: lower speeds for hardwoods and higher speeds for softwoods. Wear eye protection and secure the workpiece before drilling. If a cleaner exit is required, place a sacrificial backing board beneath the workpiece or finish the hole from both sides.
