Frequently asked questions (FAQ):
What is a knot bit?
A knot bit is a drill bit used to make particularly neat, flat-bottomed holes in wood. It is often used for hinge recesses, hiding screw heads or removing knots from wood materials.
What is a plug cutter used for?
A plug cutter is used to make wooden plugs that are fitted into holes made with a knot bit. This lets you cover screw heads or defects in the wood surface, so the surface looks finished.
Can the bits in the set be used in a cordless drill?
Yes, all the bits in the set are compatible with ordinary drills and cordless drills.
Is the set suitable for hardwood?
Yes, the bits made of hardened steel withstand drilling in hardwood. With hard wood species, however, it is advisable to use a lower speed and make sure the bit is cooled.
How should the bits be cleaned and stored?
Clean the bits after use with a brush or cloth, and store them in the wooden case supplied. A dry, dust-free storage place extends the life of the bits.
Can the plug cutters be used for anything other than making plugs?
Plug cutters are designed specifically for cutting round wooden plugs. Other uses are not recommended, as the shape of the bit is not suitable for ordinary hole drilling, for example.
How do I choose the right bit size?
Choose the bit size according to the counterbore or plug you need. For example, a 20 mm knot bit is used when you want to make a medium-sized flat-bottomed counterbore. Use the plug cutter of the same size so that the plug fits perfectly.
