SV Series Six-Point Position Stabilization Motor Bit

Model Number: 12 1/2SVT517G(IADC:517) Brand Name: TRANSTONE Key Specifications/Special Features: Cutting structureThe durability of premium tungsten carbide inserts is improved with new formulas and new techniques.Gauge StructureMultiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.Bearing structureHigh precision journal bearing with two thrust faces. Balls lock the cone. Hardfaced head bearing surface. Cone bearing inland with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed.Seal and lubricationAdvanced metal face seal lowers seal frictional force and overall seal torque and improves seal life. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.Six-point position stabilization structureThe bit leg is designed with specific integrated stabilization structure, which provides near six-point contact with borehole wall for the bit. This new feature gives the bit unequaled stability which greatly reduces bit vibration protects the cutting structure from damaging blows and keeps good borehole quality. The thickened nozzle wall can protect hydraulic system from wear and fluid erosion.Product ApplicationIt is suitable for downhole motor and high speed applications, and is the ideal selection for drilling directional and horizontal wells.
