Ulterra manufactures and sells matrix and steel polycrystalline diamond compact (PDC) bits and related downhole tools for the oil & gas drilling industry. The company manages a fleet of downhole rentals tools called TorkBuster, which optimizes drilling performance with PDC bits. Ulterra's TruGauge product is a state-of-the-art tool for directional drilling applications.

In December 2007, Ulterra acquired United Diamond, a leading manufacturer of drilling products headquartered in Alberta, Canada. In March 2010, Ulterra sold its roller cone bit business, but remains the sole distributor of these products in North America.
