Product Description:
1. Whole Q series and T series drilling sizes (B,N,P,H).
2. Various waterways design.
3. Longer bit life and high speed performance.
4. Cost effictive;
Our impregnated bits are manufactured to give optimum penetration
rates and bit life, which is required to keep the cost of diamond
drilling to a minimum.
Crown Height:
We could offers crown impreg depths of 9mm, 12mm, 14mm, 16mm, 25mm.
The taller crown heights provide improved bit stability and reduced
vibrations, enhancing bit life and performance.
Waterways:
Various waterways are available for diamond impregnated bits.
Differing waterways allow for better flushing in various ground
conditions and drilling systems.
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.
