Mining/Air Circulation Bits

  • Air Circulation
    All DBI Mining bits manufactured with Jet circulation. Airflow is employed to cool and flush the matched precision bearings, clean bit teeth and remove cuttings from the hole.
  • Cutting Structure
    Design considerations including pitch and tooth spacing are considered to ensure the bits will conquer the most extreme drilling conditions.
  • Bearings
    Bearings are triple balanced to reduce friction and eliminate unbalanced wear condition.

Frac Plug Mill

  • Our Frac Plug milling tools include hard faced mill teeth on the inner rows for aggressive cutting action to deal with the hard material found in frac applications. These cutting structures ensure optimal performance and reliablity.
