9 7/8″IADC 412/415/642/ 645/542/545

Tricone bits are the most widely used drill bits and are suitable for a variety of formations from soft to hard. The tricone bit has low torque when breaking rock, rotates smoothly, and causes little harm to drilling tools and ground equipment: the working edge is longer than that of a scraper bit, which reduces wear and extends the service life.
