1. The Purpose of Drilling and Cutting with Long-hole Cutters

Long-hole cutting machines (also called longitudinal drilling machines) are applied for drilling of round-hole bores and for drilling and cutting of long holes. According to the type of the machine you can reach maximum bore depths of 200 mm and maximum lengths of the long holes of 200 mm. The diameter of the tools can be up to 25 mm.

Round bores and long holes are the basis of wooden joints: e.g. a doweled groove, a doweled frame joint, a caulked frame joint or cutting-outs for placing mountings.

Round bores and long holes can be manufactured with long-hole cutters across and with the grain of the pieces of work.
