FMS is an authorised Atlas Copco distributor for the Focus rotary drill bit range.

Focus rotary bits are available as milled steel-teeth bits or as tungsten carbide insert (TCI) Tricone bits.

Milled steel-teeth bits can be hardened and surface treated with carbide for extra resilience. They are ideal for soft to medium rock.
TCI Tricone bits offer a variety of carbide inserts such as spherically shaped inserts for very hard rock or conically shaped inserts for softer rock.

The number of rows of inserts is directly related to the type of application and the size of hole to be drilled. There are also open and sealed bearings available as well as three types of shirttail protection to choose from.
Finally, Focus rotary bits can use both fluid and air circulation.

Mining
Focus rotary bits are put to the test when drilling blast holes in mines. The environment is tough, and inserts, bearings and shirttails are subject to drilling in hard abrasive rock.

This requires the best Focus has to offer – TCI Tricone bits. They are equipped with large roller bearings that can take maximum load, especially designed flushing holes for effective cooling and cutting removal, specially designed cone and inserts for maximum penetration and three shirttail designs to facilitate the best protection for the drill bits.
TCI Tricone bits for mining are available from 4 ¾” to 12 ¼” I n diameter.

Waterwell Drilling
Drilling for water is a demanding operation where rock conditions can vary from site to site. With Focus rotary bits, there is a multitude of cone designs with both open and sealed bearings to match these conditions.

Bits are available from 2 15/16” to 6 ¾” in diameter with milled steel-teeth or with tungsten carbide inserts. They are also designed for center fluid and air flushing.

The Range
Focus rotary drill bits come in 320 different models from small milled steel-teeth bots to multiple row, carbide insert TCI Tricone bits.
