Symmetrix Permanent Ring bit system for DTH

Atlas Copco offers a Permanent Ring bit system for DTH drilling - Symmetrix, an all-round overburden drilling system for holes of any depth or size. The Symmetrix system is a patented system comprised of an ingeniously simple concentric method of drilling through overburden with casing. Symmetrix can drill straight holes at any angle (including horizontal) and to depths beyond 100 meters. The three main components of the system are made up of:

  • A pilot bit that drills away the center part of the hole and guides the drill string.
  • A casing shoe welded to the casing pipe which is pulled down by the impact of the hammer and pilot bit.
  • A symmetrical ring bit For these components two different setups are offered by Atlas Copco. For setup one all three above mentioned components should be ordered. Setup two consits of a factory assembled ring bit set (integrated ring bit and casing shoe) and a pilot bit. Symmetrix systems can be used in a multitude of applications such as micropiling, underpinning, anchoring, marine work and horizontal drilling etc., handling casings from 76 to 1,220 mm (3 to 48 in), to almost any depth.
