Mineral Exploration Geological Wireline Coring Impregnated Diamond Bit For Hard Rock Formations

 

 

Impregnated Diamond Type for Hard Rock Formations

 

 

Impregnated core bits are manufactured by bonding diamonds into a matrix which wears away during drilling to continually expose the diamonds for the cutting of rock. This process has distinct advantages over surface set bits, which can shed diamonds from the matrix leading to premature bit failure, due to the bit drilling out the diamonds.

 

The disadvantage of impregnated bits is that if the wrong matrix is selected or the bit is allowed to ‘run on bottom’ without penetrating the matrix can ‘polish’ preventing further diamonds from being exposed. The bit then has to be ‘mechanically’ stripped to expose further diamonds. Therefore matrix selection for impregnated bits is an important factor and often is a matter of initial trial and error.

 

Generally the harder the rock, the softer the matrix. Most manufacturers have adopted a numerical identification system for their bits:- I =The hardest matrix up to 18 = The softest matrix.

 

 

Surface Set Diamond Type for Medium-Hard Conditions

 

Surface set bits are manufactured for high speed penetration, long service life and suitability for a variety of rock conditions. The range includes a variety of face profiles, diamond grades and stone sizes, enabling our customers to choose a bit that will provide optimum performance in any formation.

 

Diamond stone size: Stones Per Carat (spc)

10/15 spc: Soft to Medium Formation


20/25 spc: Medium to Hard Formation

30/40 spc: Medium Hard to Hard Formation

40/60 spc: Hard Formation

60/80 spc: Hard to Very Hard Formation

 

 

Polycrystalline Diamond Type for Soft-Medium Conditions (TSP & PCD)

 

The PCD bits have the same profile as sawtooth design bits, but the cutters are composed of Polycrystalline Diamond (PCD) which give a long working life, fast penetration and a high percentage core recovery in soft and hard formations, from clay to hard limestones. These bits are suitable for use with air, water, mud or foam flush. Several types of PCD cutters are available depending on the formation to be cored such as flat, clam or claw

 

 

Tungsten carbide type for very soft conditions

 

Tungsten carbide core bits are available to suit most sizes of core barrel, and come in a variety of types to suit different drilling conditions. Sawtooth design of bits can have various types of inserts:
