Augers

Augers are intended for drilling of degas wells on coal directly from excavations both with flushing and without it.

Augers are connected between themselves owing to the axial displacement of one auger’s nipple into the coupling of the another auger till the whole closing of augers’ stop face.

Tightness of the connection as achieved with the help of installing O-ring on the auger’s connector.

For the transmission of the rotary moment from the rig through the kit of rods to the bit it is foreseen to use the hexagon coupling and the solidity of augers there is the bolting connection of connector.

Advantages of our augers as compared with import analogues:

  1. Increased quality of the bolting connection for the solidity of the column during the drilling process.
  2. Standard kit of duplicate parts which includes in itself O-ring, pin, nut. The number of providing kits are coordinated with the customer.
  3. Price of the proposed augers is lower from the import analogue in 1.5 times.
