Surface set diamond core bits T2 86 , T2 101 , NQ ,

Surface set diamond core bits are often considered old-school tools in diamond drilling. They were the only choice for drillers years ago. Like many other things, new methods and technologies have caused diamond drilling to evolve, and diamond impregnated core bits are more common today. The surface set bit had only one layer of diamonds on the surface while with an impregnated core bit has several layers of diamonds all through the matrix.

Product Description

Surface set diamond core bits T2 86 , T2 101 , NQ , HQ

 

Surface set diamond core bits are often considered old-school tools in diamond drilling. They were the only choice for drillers years ago. Like many other things, new methods and technologies have caused diamond drilling to evolve, and diamond impregnated core bits are more common today. The surface set bit had only one layer of diamonds on the surface while with an impregnated core bit has several layers of diamonds all through the matrix.

 

Surface set core bits still have a role to play, and with the introduction of synthetic diamonds, surface set bits have become a lower cost alternative that are suitable for a variety of soft ground conditions. This kind of core bit is manufactured using a choice of diamond grades ranging from coarse to fine, and a variety of profiles, to make the core bits suitable for a range of ground conditions.

 

Choosing the right core bit is one of the most important decisions you will have to make and the same applies to surface set core bits. These are some of the factors you will need to consider when choosing a surface set core bit.
