The shell's high-quality steel body provides durability and strength, ensuring stability during the reaming process. The advanced cooling system helps to prevent overheating, ensuring that the shell remains cool and stable even during extended use.

The diamond reaming shells are available in various sizes to accommodate different reaming needs, making them versatile and suitable for various applications. Its long lifespan and cost-effectiveness make it a valuable tool for any project that requires reaming holes in hard rocks and minerals.

Professionals can use the diamond reaming shells to ensure accurate results and reduce the risk of errors. The shells are easy to use and require minimal maintenance, making them a convenient choice for those who need a reliable reaming tool.

With their durable construction, advanced design, and versatility, the diamond reaming shells are an excellent choice for anyone looking for a reliable and efficient reaming tool. Their long lifespan, cost-effectiveness, and ease of use make them a valuable tool for any project that requires reaming holes in hard rocks and minerals.

  1. Function: reaming shells are attached to the leading end of the core barrel assembly in diamond drilling systems. Their primary function is to stabilize the core barrel and the inner tube assembly while drilling , ensuring the borehole remains straight and concentric.

  2. Design: reaming shells typically consist of a steel body with natural or synthetic diamond-impregnated matrix on their outer surface. The diamonds provide abrasive cutting action, helping to maintain the diameter of the borehole and prevent deviation.

  3. Diamond Impregnation: The diamonds on the outer surface of reaming shells are embedded in a matrix material, which can be metal or resin-based. The diamond distribution and concentration are carefully engineered to ensure optimal cutting efficiency and durability.

  4. Compatibility: reaming shells are designed to match the outer diameter of the core bit they are used with. They come in various sizes to accommodate different core bit sizes and drilling conditions.

  5. Waterways: reaming shells typically feature waterways or flushing holes to facilitate the circulation of drilling fluid (usually water or drilling mud) to the cutting face of the core bit and the diamond-impregnated surface of the reaming shell. This helps to cool the diamonds, carry away cuttings, and lubricate the cutting action.

  6. Wear Resistance: The diamond-impregnated surface of reaming shells provides excellent wear resistance, allowing them to maintain their cutting efficiency even in abrasive formations.

  7. Longevity: reaming shells are subjected to high levels of wear during drilling operations. However, their robust construction and diamond-impregnated surface ensure a relatively long service life compared to conventional reaming tools.

  8. Maintenance: Regular inspection and maintenance of reaming shells are essential to ensure optimal drilling performance. This may involve cleaning, re-tipping worn diamonds, or replacing worn-out reaming shells as needed.

FAQ

Q: What does nq stand for in drilling?

A letter name specifying the dimensions of bits, core barrels, and drill rods in the N-size and Q-group wireline diamond drilling system having a core diameter of 47.6 mm and a hole diameter of 75.7 mm.

Q: What is the lifespan of a diamond drill bit?

All diamond core drills have a known average lifespan. On average, these drills can drill up to 100-250 holes before needing to be replaced. With that said, careful maintenance can help extend the lifespan of your drills beyond 250 holes.

Q: What does NQ mean in quality?

“NQ is "Normal quality" movie. HQ is "High quality" movie” This is a bit vague since depending upon the iteration of a digital SLR camera, “normal” can mean anything from HD, Full HD to UHD. The HQ also includes the bitrate that the video can be recorded.

Q: How do you deglaze a core drill bit?

To sharpen your core drill bit – to deglaze it – you need to raise the weight on your bit while reducing the water flow. When your cut begins to improve, the bit has successfully sharpened. At that point, you can return both the weight and the water to their original levels.
