Technidrill's large diameter horizontal BTA drilling machines are designed to provide the rigidity and power required for successful BTA/STS drilling. Counter rotating of the work piece for improved accuracy, or stationary part rotating tool.

Drill, Counter-bore, Trepan, Pull-bore

Diameters from .500" to 12.00"

Standard single or dual spindle machines.

Depths up to 240" or more.

Counter rotating of the work piece for high accuracy.

The BTA system also known as STS (Single Tube System) is capable of very high penetration rates as much as five to seven times that of gundrilling. 

It also provides surface finishes that often eliminate the need for secondary honing operations.

Diameters from .500" to 12" inches.
