It’s not magic – only clever engineering

Omega S begins life as a single-sealed bearing bit. After the seal has worn off, the bit automatically transforms into an air-bearing bit – adding 30 percent extra lifetime. 

The function

Each cone is equipped with a durable hydrogenated nitrile butadiene rubber (HNBR) seal, which enables vacuum lubrication of the bearings. Once the seal fails and vacuum is lost, cooling air begins to flow over the bearings. This automatically transforms Omega into an air-bearing bit – adding extra lifetime.

The benefit

Omega S has an outstanding longevity. The bit provides up to 30 percent more drill meters than a standard air-bearing bit. This gives Omega S an excellent price–performance ratio, perfectly positioned between standard air-bearing bits and premium-quality double-sealed bits such as Omega.

The users

Omega S is targeted at professional drilling specialists in the mining industry, mainly CPM (cost per meter) contractors with operations in coal, gold, copper and iron ore mines. It is particularly efficient in wet and fractured rock formations, in locations with high water injection for dust suppression.

Each component is important

When developing a rotary drilling system, most of the attention is given to the drill rig – the capital equipment that requires significant investment and hence a planned payback. The second priority in the system tends to be choice of rotary tricone drill bit. However, to utilize the full power and capacity of the rig and the bit, and at the same time increase service life and productivity, serious consideration should be given to each component in the drill string.

 

The drill string’s primary purpose

The primary purpose of the drill string is to transmit the rotational torque and weight from the rotary head power source to the rock breaking drill bit.  As in every rock drilling method, the power must be transmitted as efficiently as possible, and return as few vibrations as possible, as these cause unnecessary wear on the drill rig and reduce penetration rates.
