Exclusive video: Helios Inferno cutter technology customizes bit to optimize performance

Tailoring cutters to specific applications is the key to National Oilwell Varco’s Helios Inferno cutter technology. Launched this week at the 2014 IADC/SPE Drilling Conference in Fort Worth, Texas, the technology takes into consideration three characteristics for the cutter: thermal resistance, abrasion resistance and toughness. In this video, Tom Roberts, NOV Product Line Director for Cutting Technology, discusses the development of the cutter index and the tests used to engineer bits for specific applications.
