These bits are used to drill high-compressive strength, medium hard formations.
1) A small amount of cone offset and low insert projection is used to prevent cutting structure damage when hard streaks are encountered.
2) Increased numbers of blunter, smaller diameter inserts are used to increase life in harder, more abrasive formations.
