BTA Deep Hole Drilling Machine

Solid drilling to Ø 250 mm Counter-boring to Ø 400 mm  Drill depths to 12,000 mm*
BTA deep hole drilling machines from Tibo provide the optimum method for larger drill diameters of 18 mm to 250 mm solid drilling (up to 400 mm counter-boring) and drill depths of up to 12,000 mm.

With the BTA method, the coolant is introduced and removed and the chips are transported away in exactly the opposite way to the gundrilling method: Thanks to the larger diameter of the BTA drill, here it is possible to reliably and continuously remove the chips through the tool's interior. The coolant on the other hand is introduced from the outside and under pressure through the annular gap between the bore hole and the drill by means of a coolant pressure head (BOZA).
