Product Description



NQ Impregnated diamond bit Turbo Type for wireline coring drilling ( Mineral Exploration)

Recommended for competent rock, hard and compact formations. 

• Good fluid and cuttings evacuation to keep the waterways clean.

• It provides greater penetration rates in most competent formations.


Our diamond core bits are ideally suited to modern drilling conditions. The impregnated diamond core bits are designed and manufactured to give optimum productivity and bit life, required to maintain cost efficiency for your drilling application.
Impregnated diamond core bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer of the "CHINA GEOLOGICAL EQUIPMENT GROUP" contains a uniform distribution of these crystal that are embedded in a powdered metal bond.
