Profidrill BTA deep hole drilling machines

BTA deep hole drilling machines from Profidrill provide the perfect solution for larger drill diameters of 18 mm to 500 mm solid drilling (up to 700 mm counter-boring) and drill-depths of up to 18,000 mm.
One of the major characteristics of BTA deep hole drilling is that the coolant, in contrast to the gun drilling method, is introduced and removed in the opposite way: Thanks to the larger diameter the drilling chips can be removed through the tool’s interior, whereas the coolant is introduced via a coolant pressure head (BOZA) from the outside through the annular gap between the bore hole and the drill.
Profidrill BTA deep hole drilling machines are also available as single-spindle and multi-spindle versions.
By selecting different gearboxes and depending on the drilling task different drive variants can be accomplished.

Deep Hole drilling can be performed in 3 manners:

  • Rotating tool, stationary workpiece
  • Rotating workpiece, stationary tool
  • Counter rotating tool and workpiece
