This steel-tooth series of products, available from 3-3/4” to 13-3/4,” delivers rapid rate of penetration (ROP) and new hardmetal protection that provides life-enhancing durability in the most demanding environments. DuraTech bits can withstand the added stress that operators place on bits when additional weight and greater RPMs are necessary. The series is designed to provide: • Added durability in abrasive environments • Increased ROP • Directional responsiveness • A solution for sticky shale drilling Designed for Durability Varel used a systematic approach when developing the DuraTech series, delivering a product that can reliably withstand high-energy inputs while maintaining expectations of high ROP and increased footage. DuraTech bits combine innovative manufacturing processes, quality materials and highly trained personnel, and have repeatedly been proven in field tests to provide reliable, lasting performance. Additionally, Varel’s extensive technology platform delivers patented advancements in DuraTech’s seal and bearing package. DuraClad™ Hardmetal Technology During development of DuraTech bits, welding specifications for hardmetal application were investigated, reviewed and adjusted to produce accurate, repeatable outcomes. The DuraClad Hardmetal Technology specifications now allow for a 20 percent increase in hardmetal application to the critical areas of the bit. This produces a bit with a more durable, long-lasting cutting structure. Skilled welders are provided with extensive application training and are regularly audited as part of Varel’s commitment to quality.
