Product Description

Product Description

1. Motor hardfacing: Tungsten carbide particle hardfacing is applied liberally along the shirttail and extended up the leading edge of the bit leg for additional protection in high-speed, directional or abrasive applications.

2. Shirttail Compacts: Tungsten carbide compacts are added to the shirttail to reduce leg wear in abrasive formations and deviated or horizontal wellbores.

3. G-Gauge protection: more tungsten carbide inserts are placed in the gauge to reduce the wear in the abrasive formation. It can protect gauge and increases the stability and life of the bit.

4. Cutter: premium carbide teeth having increased resistance to breaking and abrasion , maximum increase cutting structure operating life.

5. Nozzle:These nozzles are much sturdier and provide greater flow capacity and maximize fluid distribution to the cones.
