T2-76mm Impregnated Diamond core bit for geotechnical coring
drilling
Description:
T2-76 Impregnated diamond bit
The impregnated diamond core bit is the most commonly used type in
the mineral exploration and the construction industry. The
advantages of using impregnated diamond core bits over bits
manufactured with other cutting media include:
- To drill a board range of geological formations from the softest
to the hardest rock and from fractured, abrasive to consolidated
formations.
- To be manufactured with very small, high quality synthetic
diamonds mixed evenly through a metal matrix. Their multi-layered
structure results in better overall bit life than other type bits
of cutting media. They give an efficient and stable cutting action
throughout the life of the bit.
- To be particularly well suited for drilling in hard, consolidated
and non-abrasive formations.
The matrix layer of the bit crown contains a uniform distribution
of synthetic diamond crystals that are embedded in the special made
matrix. When matrix layer is eroded the new layers of sharp
synthetic diamond will expose controlled until the matrix layer of
the bit crown is totally consumed. The function of the impregnated
diamond core bits, such as overall bit life and penetration rate
are dependent on the grit size, concentration and grade of the
synthetic diamond crystals are well as the relative hardness and
property of the metal bond materials
OBI have developed a range of impregnated diamond matrices with
matrix layer metal bonds that range form hard, abrasion resistant
types to soft, ductile types. Individual matrix types are
identified by number designations which are marked at the collar of
the bits and also can be identified by the paint color inside of
the bits. The relative hardness of the metal bond hardness
decreases as the matrix number designations increase.
Diamond-impregnated bit
1. High quality and best price
2. Huge stock and good service
3. Long service life
Main features:
1. Better resistance in most forms, especially in very hard rock
forms
2. Abuse rough handling and improper use will cause less harm
3. Self-grinding due to matrix erosion and diamond
4. High quality synthetic diamonds are evenly distributed
throughout the matrix
5. High efficiency cutting function continuously provides fresh,
sharp diamonds
