Description:

Thepolycrystalline diamond bits consist of a designed cast matrix head to which PDC inserts have been fixed in a pattern, the natural diamond on both sides to protect the waterways. The PDC bits, include the core and non-coring types, have been used in soft to medium formation of hardness 3-6.

The surface of the disc-shaped cutting element consists of very fine synthetic diamond powders sintered together by a high pressure, high temperature process. Backing this diamond layer is a tungsten carbide stud which is brazed directly into the bit matrix by a special process. These cutters can take the enormous compressive and shear loads generated during drilling without failure or erosion. PDC core bits are ideal for use on high powered drills at relatively low rotation speeds. Remarkable results have been obtained both in bit life and penetration compared with surface set bits. Core recovery is also enhanced due to the faster penetration.

Advantages:

PDC core bits have proved to be exceptionally cost effective for geotechnical drilling and have extremely fast penetration rates and a very long working life.

Category:

A wide range of full-hole drill bits with polycrystalline diamond cutters (PDC) are available for numerous applications in mining, civil engineering and the oil and gas industries.
