Polycrystalline Compact Diamond Core Drill Bits For Rock / Sintered
Flat PDC Core Bits
Sintered Flat PDC Core Drill Bits Polycrystalline Compact Diamond
Bit for drilling soft with fractured rock formation
Detailed Product Description:
Sintered Flat PDC Core Drill Bits Polycrystalline Compact Diamond
Bit
Ideal for drilling in soft to medium sedimentary formations which
are homogeneous and competent. The PCD cutters are available in
several sizes and are located to yield maximum penetration rate and
long life depending on the application. The bits are constructed
with a tough, wear-resistant matrix body and gauge reinforcement.
As a result, worn cutters can be rotated or replaced allowing the
continued use of the bit.
Product Advantages:
1. PCD sintered bit with premium PCD teeth;
2. Tungsten carbide as the drill bit body;
3. Over 50 years manufacturering experience;
4. Solid quality;
5. Cutter layout is force balanced to drill a precise round hole
and reduce bit whirl;
6. Large junk slots and flushing ports;
7. Advanced geometric design for faster penetration;

Introduction of PDC (Polycrystalline Diamond Compact):
PDC is made of diamond micro-powder and hard alloy substrate under
high temperature and high
pressure. It possess of high wear resistance like diamond, at the
same time the impact resistance like hard alloy and that’s made it
the best material as a drill bit cutter. Reinforced PDC has higher
dense diamond powder, claw hard alloy substrate made the two layers
solid as whole one. So, the reinforced PDC of supper wear
resistance, longer service life and high efficiency.
Features:
1. Suitable for soft to medium mations(f=1-10), particularly
suitable for harder rock construction, not available in broken,
fractured, strong abrasive formations.
2. The bit body are adopted advanced sintering technology, have
high strength and good gauge protection;
3. High quality polycrystalline diamond compact (PDC) cutters as
the cutting teeth and advanced welding technology make the bits
have stable quality.
4. The bits have strong stratum applicability, high drilling
efficiency and long life. The various performance are much better
than steel body PDC bits.
