Precihole BTA Drilling Solutions

BTA drilling is the ideal process for a range of larger deep hole drilled depths and diameters. BTA deep hole drilling and secondary processes are capable of drilling extreme depth-to-diameter ratio holes while achieving strict tolerances.

BTA stands for the “Boring and Trepanning Association,” which is responsible for developing this deep hole drilling process. Sometimes referred to as STS (single tube system) drilling, BTA/STS drilling is generally used for ф 19mm and above. BTA drilling finds its application in industries such as oil and gas, defense, steel, aircraft and aerospace, hydraulic cylinders, and energy. For larger diameter deep hole drilling, BTA drilling is the only available option that can provide high productivity and precision.
