Varel International Announces Launch of DuraTechTM Series Roller Cone Bits

(CARROLLTON, Texas- 20 September 2011) - Varel International, a leading manufacturer of drill bits and global supplier to the drilling industry, is proud to introduce the next generation of steel tooth roller cone bits - the Varel DuraTechTM Series. This series delivers ultimate rates of penetration (ROP) with reformulated hardmetal protection that provides life-enhancing durability in the most demanding environments.

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 patent pending advancements in DuraTech's seal and bearings package.

  • Enhanced Hardmetal - Newly enhanced DuraClad Hardmetal Technology includes specifications that provide a 20 percent increase in hardmetal application to the critical areas of the bit.
  • Manufacturing Process Controls - During development of DuraTech bits, welding specifications for hardmetal application were investigated, reviewed and adjusted to produce accurate, repeatable outcomes.
  • Expertly Trained Personnel - Skilled welders are provided with extensive training, assist in writing specifications and are regularly audited as part of Varel's commitment to quality.
  • Patented Heat Shield - The heat shield ring is deployed between the seal and inner bearing and acts as a thermal insulator to the seal from heat generated in the bearing.
  • Patented Conical Seal Gland - The newly designed seal gland is constructed to resist cuttings packing into the seal area.
  • Improved Bearing Grease - DuraTech bits have incorporated a high temperature, high lubricity bearing grease assisting in the reduced generation of internal bearing heat allowing bearings to last longer.

Performance results continue to validate the success of the DuraTech bits in applications ranging from sticky shale drilling to ultra-abrasive salt applications
