Product Description:

BTA Deep Hole Drilling is a technique utilized for drilling exceptionally deep and straight holes in metal components, typically when the hole's depth exceeds its diameter. The method derives its name from the Boring and Trepanning Association.

During this procedure, high-pressure coolant circulates around the exterior of a specialized drill tube, converges at the cutting zone, and propels the metal chips outward through the center of the drill bit. This ensures a tidy, quick, and precise drilling process.

BTA drilling finds common application across industries such as oil & gas, aerospace, and hydraulic systems for creating deep bores in items like gun barrels, hydraulic pistons, and mechanical parts. It is most effective for hole diameters exceeding 20 mm, boasting rapid speeds and the production of sleek, aligned bores.
