Varel Challenger™ roller cone bits are designed and manufactured to provide high levels of performance and reliability. Challenger™ products are the result of years of industry experience and thousands of hours of field tests in the most demanding applications. Every detail of the design and manufacturing process results in a product that meets or exceeds the requirements of our customers, every time. Advanced cutting structures for high energy applications, High Energy Tumbling™ (HET) technology (patent pending) for extended cutting structure life and bearings for motor applications are just a few of the features incorporated to meet the challenges of Canada’s drilling environments.
Challenger™ steel tooth bits are manufactured with Varel’s exclusive forged tooth process. This innovative method provides stronger, more impact-resistant teeth when compared with milling because the metal flow lines from the forging process follow the tooth contour instead of being cut by machining. Advanced cutting structures engineered to provide the lowest possible drilling costs. Each design has the row placement, tooth spacing and geometry designed to provide the highest drilling efficiency, minimize tooth wear and prevent tracking in a wide variety of formations and conditions.
