Grain styles perform best in enclosed environments of oil. Under magnification it has been noted that oil accumulates in the areas where washand erosion of the matrix happen. This holds tiny pockets of oil, which helps in lubrication of the bearings.
Typical life expectancy: 300 – 400 hours (Run life solely depends upon drilling environment, mud composition, bend settings, carbide saturation and quality)
