Natural 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.

A natural diamond reamer is a tool that uses natural diamond particles as cutting/grinding materials. It performs reaming, dressing or precision processing on hard and brittle materials such as stone, ceramics, glass and concrete through rotation or vibration. The core of it is to fix natural diamond particles on a metal substrate (such as steel or hard alloy) through electroplating, sintering or brazing processes, and achieve efficient processing by taking advantage of the extremely high hardness and wear resistance of diamond.

Core advantage

1. Ultra-high hardness and wear resistance

Natural diamond is the hardest substance in nature (with a Mohs hardness of 10), which can remain sharp for a long time and has a much longer lifespan than ordinary tools. It is suitable for high-intensity and long-term operations.

2. Precision processing capability

Diamond particles can achieve high-precision reaming and dressing of hard and brittle materials. After processing, the hole walls are smooth and the dimensions are accurate, reducing the subsequent polishing process.

3. Low risk of thermal injury

Diamond has good thermal conductivity. During the grinding process, heat dissipates quickly, preventing the material from cracking or chipping due to high temperatures. It is especially suitable for fragile materials such as glass and ceramics.

4. Wide applicability

It can process super-hard materials that are difficult to handle with traditional tools, such as granite, sapphire, silicon carbide, etc., and is widely used in geological exploration, construction engineering, jewelry processing and other fields.

5. Strong environmental adaptability

Natural diamond has stable chemical properties and is resistant to acid and alkali corrosion. It can still maintain its performance in harsh environments such as moisture and dust.
