Japanese Knot-hole repair Set

This conical drill and dowel cutter set can be used to repair loose or unsightly knots and other defects in a clean and efficient manner. Conical dowels can be fitted more tightly than cylindrical dowels and do not diminish the strength of the piece when glued in place. We recommend using a Japanese saw for cutting off the tops of the dowels without marring the wood’s surface.
HSS drill bit, aluminium dowel cutter, resharpenable carbon steel cutter. With wooden case and instructions.
Hole Ø 5 - 25 mm, drill length 80 mm.
