Home Drilling Equipment Drilling Tools Destroyer Bits

Dando Drilling supplies a wide range of coring and non-coring bits within its ‘Destroyer’ range. They have been used globally by clients in both the mineral and geotechnical sectors, receiving positive feedback for their high performance rates. 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.

Dando has recently supplied a range of ‘Destroyer’ HMLC PCD bits to one of its clients on a large mine site overseas and received the following feedback:

“Following recent work with the Dando Destroyer HMLC PCD core bits which were supplied, the test results received have proven to be very positive with our recovery of coal cores achieving more than 90%. We are very satisfied with the performance of core bits produced by Dando and are pleased that they have enabled us to improve our performance rate.”
