The Dando Drilling ‘Destroyer’ range includes a wide range of coring and non-coring bits.

They have been used globally by clients in both the mineral and geotechnical sectors, receiving positive feedback for their high performance rates and longevity.

All bits are manufactured to conform to accepted drilling industry standards but can also be supplied in non-standard designs for clients with specific requirements.

There are four types of cutting media to accommodate the various types of geology:

  • Impregnated diamond type for hard rock formations.
  • Surface set diamond type for medium-hard.
  • Polycrystalline diamond type for soft-medium conditions (TSP & PCD).
  • Tungsten carbide type for very soft conditions.
