Release–High Roller™ Series Roller Cone Bits
Varel announces the commercial launch of new Higher Roller series roller cone drill bits. The bits, ranging from 14-3/4” to 18-1/2”, are sealed roller bearing designs with either Mill Tooth or Tungsten Carbide Insert cutting structures.
This series responds to increasing demands on larger diameter roller cone drill bits that are being applied with greater weight on bit (WOB) and higher rotations per minute (RPM) than ever before. Varel bit designers worked to tailor specific cutting structure designs to match the challenging operating requirements and parameters directional and rotary steerable drilling require.
Using the solid foundation of the proven High Energy™ technology, this innovative addition to the roller cone product line includes the company’s patented conical seal geometry technology along with a new, larger lubricant reservoir, which allows High Roller bits to support longer bit life and increasingly demanding applications.
