Wood drill bit set for square holes

The drill hole becomes round, splintered – and the tenon simply doesn't fit.

Anyone who has to manually rework tenon joints loses time and patience. With this precision wood drill bit set, clean square holes are created in a single drilling pass – no chiseling, no sanding, no rework. The result fits precisely to the millimeter immediately, whether pine or oak.

Advantages

• No more splintered drill holes: Instead of reworking and sanding, you get clean, dimensionally accurate results immediately – right on the first drilling pass.
• Hours of manual labor eliminated: What used to require chisels and files is done by the set in seconds – and the result is perfect from the start.
• No doubt about stability or fit: The carbon steel construction stays sharp permanently, so you don’t have to wonder whether the drill bit gives way in hard woods.

Application

1. Clamp: Insert the desired drill bit into the standard drill – no special chuck needed.

Pro tip: For hardwoods like oak, reduce the drill speed to medium – this keeps the cutting edge sharper longer and produces an even cleaner hole.
