Durawing

 

DURAWING is a concentric overburden system designed for casing installation drilling range of 4” to 32” diameter hole, specialized through various formations into bedrock.

 

The wings are enclosed in the pocket area making it the most professional & efficient system in the

market as it is free from clogging in loose overburden material while it goes down to bedrock. When the drilling starts, wing bits come out with unique cam sliding mechanism. The key feature of DURAWING is the self-actuating wing bit system that is reliable regardless of unpredictable ground conditions.

Features and Benefits

  • Unique sliding mechanism leads to absolute workability

  • Simple parts replacement

  • Low running cost

  • Same performance in horizontal drilling

  • Prevent jamming with internal air exhaust
