Pcd bits

The structural feature of the bits with polycrystalline diamond inserts is a cast die head reinforced with circular polycrystalline inserts with a diameter of 13.3 mm, arranged in a specific order. When drilling without casing, coreless bits are used.

Drills with polycrystalline diamond inserts show the greatest efficiency when drilling soft and medium hard formations. They are widely used in the exploration of coal deposits and during preliminary drilling without casing before the core drilling.

In addition, these bits are used for degassing mines and for horizontal drilling when laying pipelines using a trenchless method.
