Surface set diamond non coring bits

Diamond non coring bits have many important applications in the construction and oil and gas industry. These drill bits have features that make them ideal for drilling through hard rocks and geological formations. The arrangement of the diamond cutters makes it possible for the drill bits to cut effectively and efficiently. That is why they are used for heavy duty applications.

In general, drills are equipped with capabilities to penetrate abrasive and hard formations, drill bits are added on that drilling in specific locations. Built with natural diamonds, synthetic diamonds, polycrystalline diamond compact cutters, thermally stable polycrystalline diamonds, grit hot pressured inserts, these drill bits are geared towards heavy duty work.

Impregnated diamond non coring bit hole sizes are available in 56mm, 60mm, 76mm. different diamonds are exposed to drill at different times and not simultaneously altogether, and this allows fresh and sharp diamonds to be exposed at different times and hence, increasing the effectiveness of the drilling process.

Surface set diamond non coring bit hole sizes are available in 56mm, 60mm, 76mm, the bit crown full of imported natural diamond frits of 20/30, 40/60, all diamonds on the crown of a surface set type are more efficiently for drilling, but entails a lower lifetime compared to impregnated diamond non coring bits.

Surface set diamond non coring bits

This non-coring drill bit has a layer of diamond grifts which are regularly arranged on the surface of the bit. In contrast to the impregnated drill bits, all the diamonds in this bit are exposed for cutting simultaneously. This makes them ideal for many high-speed drilling operations because they offer fast penetration. However, they tend to wear out faster than impregnated bits, so they are recommended for soft, abrasive formations. Surface set non-coring bits are effective in drilling kinds of formations and surfaces, the quality and combination of diamonds may also be altered so it can be used to drill harder, less abrasive surfaces, hole size are available in 56mm, 60mm,76mm.

Natural diamonds are arranged on the crown of a metal matrix body which is fused to a steel body, all diamonds on the crown of a surface set type are exposed at the same time. The great thing about surface set drill bits is that they are significantly effective in penetration, this is because they are designed with non-coring technology to provide the efficient cutting in the given formation which is being drilled. They are most effective in drilling through sedimentary rock formations and it does so at the lowest cost.

However, the fact that there is only a layer of diamonds on the surface of the matrix, this surface set diamond non-coring bit entails a lower lifetime compared to other types. The good thing about this type of bit is that it can alter the variations of used diamonds and their formation set on the crown to suit different drill surfaces, variations in diamond size and quality and the type of arrangement affect the effectiveness of the drill in different applications.
