Drill stabilizer
The overall three-helix and four-helix stabilizers are divided into bottom hole type and drill string type. The wear-resistant materials (ie centralizers) on the working surface include cemented carbide pillars on the surface, diamond composites on the surface, and hardfacing electrodes, Various forms such as low temperature brazing hard alloy.
