BTA Deep-Hole drilling machines
BTA is the acronym from Boring and Trepanning Association which developed the BTA system. It involves a single drill tube in which high pressure coolant is supplied to the drill through the annular area between the drilled hole and the tube outer diameter. The chips are evacuated through the interior diameter of the tube. Compared to Gun Drill system, BTA allow removing much thicker metal area, obtaining wider diameter holes. The minimum diameter is 10 mm.
