China T2-76 Impregnated Diamond Core Bit

T2 series core bits are used for surface exploration with the T2 series core barrel.
Impregnated Drill bit Diamond Core Bit can handle a broad variety of rocks.
Product Description
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.
The choice of the diamond bit crown shape:
W Profile
Suitable for drilling hard dense formations with high penetration rate.
Semi-Round Profile
Impregnated bits with this profile are recommended for use in highly fractured formations with good drilling stability. Surface set bits of this style have a long bit life and the matrix is not easy to be damaged.
Flat Profile
It's suitable for various rocks, often used in impregnated casing bits, casing shoes as well as the bits with very hard matrices(e.g. F1, F2).
Cross Profile
It's especially designed for ultra-hard formations, such as granite (hardness 8-9), ganister, quartzite, siliceous limestone, chert, etc.
Multi-Step Profile
Multi-Step type impregnated bit are suitable for soft to medium hard formations and alternating hard-soft formations. With very good drilling stability, it makes the borehole not liable to deflection and the penetration fast. This profile is also often adopted in thick-kerf surface set core bits, with good drilling stability and fast penetration.
Shaped Gear Profile
It's suitable for competent formations, and can expand the flushing ways and improve the penetration rate.
Face Discharge
It's suitable for sedimentary and metamorphic formations, or the formations including with lots of mineral powders, this design can protect the core from flushing and improve the getting effciency of core samples.
