How to choose diamond core bit? Laser welding or High frequency welding?

When choosing a diamond core bit, there are a few factors to consider. One important factor is the type of welding used in the manufacturing process. Laser welding and high-frequency welding are two common methods.

Laser welding involves using a laser to melt and fuse the diamond segments to the core. This method provides a strong bond and excellent heat resistance, making it suitable for cutting through hard materials. Laser-welded diamond core bits are often more durable and can withstand higher temperatures.

On the other hand, high-frequency welding uses a high-frequency current to bond the diamond segments to the core. This method offers good cutting performance and is often more cost-effective. High-frequency-welded diamond core bits are suitable for general-purpose drilling and can work well on various materials.

The choice between laser welding and high-frequency welding depends on your specific needs. If you require a diamond core bit for heavy-duty or high-temperature applications, a laser-welded bit may be the better option. However, if you need a more affordable option for general drilling tasks, a high-frequency-welded bit can be a suitable choice.

It’s also essential to consider the quality of both the diamond segments and the core material, as well as the intended drilling application and the type of material you will be drilling through. Consulting with experts or a reputable supplier can help you make an informed decision based on your specific requirements.
