STS (BTA) Drilling System

The STS (BTA) drill is a single tube drilling system used in deep hole drilling applications where fast metal removal is needed. Drill sizes in STS drills are from 0.312”-2.559” diameter. Drills are manufactured in multiple grades and coatings to fit individual customer requirements. Brazed STS drills can be re-tipped at our facility to an “as new” condition at a significant cost savings to the customer.

These drills require high pressure coolant to flush the chips through the tube, to the chip box. We manufacture tubes in house to customer specified length for all sizes.

  • Tube sheet manufacturing
  • Auto – crankshaft, steering, gear and transmission
  • Heat exchanger manufacturing
  • Hydraulic cylinder manufacturing
  • Oil & gas
