Atlas Copco Secoroc’s PrimO pilot bit employs enhanced features to increase the bearing and cutting structure life of the current pilot bit design.
The PrimO pilot bit features a contoured shirttail to reduce heat on the seal area and carbide inserts on the shirttail to increase the life of the shirttail and seals. The PrimO also employs a dual seal arrangement that includes a primary seal and an excluder for longer seal life. Longer seal life in adverse conditions means longer running hours in the pilot hole and longer holes.
In addition, the PrimO design incorporates the use of extremely hard carbide on the cone gage bevels coupled with enhanced carbide on the gage of the bit to reduce wear and improve gage life. Improved gage life means longer pilot holes with fewer trips for the customer and overall faster penetration rate as the insert retains shape longer.
The PrimO pilot bit also utilizes proprietary synthetic lubricants for higher loads, longer bearing life and increased RPM.
The combined features of the PrimO bit have shown performance in a field test 30 percent higher than the standard product in hard, difficult ground conditions, according to the manufacturer.
