High quality slotted hole drilling machines and a particularly good supply of spare parts.
Slot drilling machines are used, as the name suggests, to drill long holes, mostly in wood. In principle, they are like an ordinary drilling machine, but they are not operated manually, instead they run on guide rails. In addition, the long-hole drills themselves have another special feature: the spiral of the drill is made of a fine thread and so the excess chips are transported to the outside even from deep, long holes. This means that it is virtually impossible for the hole to be drilled to become clogged during the drilling process. A long-hole drilling machine is mainly used in woodworking.
