B76 Impregnated bits / Diamond Core Drill bits for Mineral Exploration Core Drilling
B76 Impregnated bits / Diamond Core Drill bits for Mineral Exploration Core Drilling
B76 Diamond Core Bit / Impregnated Core Drill Bits 61.57 ~ 61.82mm
B76 impregnated and granular material of the drill bits
The impregnated diamond bits are the most commonly useful bits in the mineral exploration industry, as impregnated diamond bits 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 crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond.
The matrix of our impregnated diamond bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action.
Our impregnated diamond bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.
Our impregnated bit HQ3 NF3-4, used in a diamond core drilling project in Armenia, has broken a world record, for it drilled nine holes up to 1533.5 meters of depth and was used for periods up to 2 months. This geological exploration project, taken by Armenia Major Drilling Group, used our bits for drilling basalt (abrasive) sedimentary shale and siltstone (non-abrasive), whose hardness is medium to soft(Refer to Details).
Advantages of B-Series Diamond Core Bits:
The B-Series diamond bits are cutting tools. They are widely be used for wire-line core drilling. They contain diamond segments bonded to a base material.
The Bits could be impregnated, they are single tube core drill bits.
They are widely applied in cutting non-ferrous materials.
Roschen's bits are using high quality diamond materials and also based on Roschen’s exquisite technology.
Features of B-Series Diamond Bits:
1. Wide hardness range. Roschen could produce the bit matrix bond hardness from 5 to 55°, Mohs hardness from Series 1 to 15.
2. High drill speed.
3. Longer service life.
4. Competitive prices.
5. 60 years experience in manufacturing diamond core bits.
