Wood drill bit set for square holes

The drill hole becomes round and frayed – and the tenon simply doesn’t fit.

Anyone who has to rework tenon joints by hand 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 perfectly to the millimeter right away, whether pine or oak.

Advantages

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

Application

1. Clamp in: Clamp 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 makes the hole even cleaner.
