Synthetic Diamond Reamer

Introduction: The reaming shell is an integral part of a diamond drilling system and acts as a coupling between the core bit and the outer barrel. It reams the hole to the proper size, and stabilizes the bottom of the drill string.

APRdrills' reaming shells are made with high-quality, synthetic and natural diamonds, embedded in a highly resistant matrix. The friction-resistant tungsten carbide inserts found on the leading edges of the ring provide additional protection and increased lifespan.

Reaming shell features one diamond ring, which is standard and effective in the majority of competent bore holes. It is used for every kind of rock hardness or ground condition and is the minimum reamer requirement to provide minimum stabilization.

The synthetic Diamond Reamer is a tool that uses labor-synthesized diamond particles as cutting/grinding materials. Diamond particles are prepared through high-temperature and high-pressure (HPHT) or chemical vapor deposition (CVD) technology and fixed on a metal substrate (such as steel or hard alloy). Its working principle is similar to that of natural diamond reamers. It expands, refines or precisely processes hard and brittle materials (such as stone, ceramics, concrete, etc.) through rotation or vibration, but the core material cost is lower and the performance is controllable.

Core advantage

1. High cost-effectiveness

Artificial diamonds, produced industrially, are much cheaper than natural diamonds and are suitable for large-scale applications and projects with limited budgets.

2. The shape and size of the particles are controllable

By adjusting the synthesis process, the particle size, shape and distribution of diamond particles can be customized, enhancing the consistency and efficiency of processing.

3. Adapt to diverse demands

The diamond concentration and binder type (such as metal, resin, ceramic) can be selected according to different processing scenarios to optimize wear resistance, cutting speed or processing accuracy.

4. Improvement in high-temperature stability

Some synthetic diamonds enhance their oxidation resistance through coating techniques (such as titanium coating), reducing performance degradation during high-temperature operations.

5. Environmental Protection and Sustainability

It does not rely on natural diamond resources, reduces the environmental impact of mining, and conforms to the trend of green manufacturing.
