Frequently Asked Questions
What square hole sizes can this mortise chisel make?
This set covers 6 mm to 16 mm square holes with the included twist drill and square chisel combination, ideal for mortise-and-tenon joints in furniture and cabinetry.
How is the twist drill matched to the square chisel?
The twist drill bores the waste hole first, then the square chisel squares it out. Choose a chisel set whose square size matches your twist drill diameter (e.g. 6 mm twist + 6 mm square).
Can it cut clean mortises in hardwoods like oak and mahogany?
Yes. For dense hardwoods we recommend lower RPM and steady feed. Carbide-edged chisels handle oak, beech and mahogany cleanly; HSS versions suit softwood and MDF.
What if the chisel goes off-center or burns the wood?
Off-center holes usually mean a worn or loose twist drill, or the chisel is rotating the wrong way. Burning means feed is too slow or RPM too high – retract frequently to clear chips.
