General Application Chart for Mineral Exploration Bits.

 

 

Impregnated Diamond Core Bit

The impregnated diamond core bit has emerged as the most commonly used type in the mineral exploration industry. The advantages of using impregnated diamond core bits over bits manufactured with other cutting media include: An extremely wide range of application. A simple crown geometry that makes them less susceptible to in-hole damage than bits produced with other types of cutting media and as such are more tolerant of changing or banded geological formations. Their multi-layered cutter arrangement results in better overall bit life than bits produced with other types of cutting media. They are particularly well suited for drilling in hard, consolidated, non-abrasive formations.

HR-Series Impregnated Diamond Core Bits

In addition to our standard range of D-Series impregnated diamond core bit matrices, Dimatec also offers our high performance HR-Series range of impregnated diamond matrices.

Dimatec’s HR-Series impregnated diamond core bits have been specifically designed for use in Hard Rock drilling applications where formation conditions are generally consolidated and fine grained with high compressive strengths and Mohs hardness values in the 6 to 8 range. Traditionally, it has been necessary to apply higher bit loads when drilling under these conditions in order to achieve acceptable rates of penetration – usually at the expense of overall bit life and premature wear on drill string components.

After conducting extensive field tests with the HR-Series range of impregnated diamond core bits, several performance benefits have been identified. These include: Very smooth cutting characteristics throughout the life of the bit when drilling through even the hardest formations.

A relatively low weight-on-bit is required to maintain a high rate of penetration. In some cases, a reduction in bit load of as much as 30% has been realized with HR-Series bits while achieving or exceeding the penetration rates of competitive products. The application of lower bit loads results in less wear and tear on drill string components as there is less potential for flexure or over-tightening of the thread connections. Under most conditions,

HR-Series bits are self-sharpening. Very little intervention by the drill operator is required to keep the bit cutting steadily.

HR-Series bits have demonstrated an ability to drill through fractured formations with significantly fewer core blocks than competitive products. Improved overall bit life and exceptional production rates in harder, consolidated and fine grained formations.

Surface-Set Diamond Core Bit

As the name suggests, the surface-set diamond bit differs from the impregnated diamond type in that they are set with a single layer of natural drill diamond on the working surfaces of the bit crown in a pre-determined pattern.

The diamonds are mounted in a bit crown powdered metal matrix body that is fused to a steel tool body or shank. Unlike impregnated diamond bits where the controlled erosion of the powdered metal bit crown is desirable to expose new diamond crystals, the metal bond matrix used for all Dimatec surface-set bits is extremely tough and wear resistant. The function of the bit crown matrix body on a surface-set bit is to securely hold the diamonds in position throughout the operational life of the bit.

Surface-Set diamond bits are primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bits. They are also recommended for use in drilling harder formations where the available rotational speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.

In most cases, surface-set diamond bits will provide higher rates of penetration than impregnated diamond bits in softer formations due largely to the greater degree of exposure of the individual diamond crystals. However, as they are set with only a single layer of diamond crystals,surface-set diamond bits will generally yield a lower overall bit life than impregnated diamond bits.

Geotechnical Core Bits

This group of products are similar to surface-set diamond bits in that they are set with a single layer of cutters mounted on the face of the bit in a pre-determined pattern. Instead of natural drill diamond however, the cutting media used on geotechnical bits are synthetic polycrystalline diamond elements. These elements are composed of micron-sized particles of synthetic diamond that have been formed into various geometric shapes. Like surface-set diamond bits, geotechnical bit crowns consist of a tough wear resistant matrix body that as a minimum includes natural diamond gauge protection setting. In most cases, the gauge protection setting augmented with seismic grade tungsten-carbide pads and/or polycrystalline diamond elements..

Reflex ACT


Reflex ACT is an electronic core orientation device, designed to achieve accurate and consistent orientations for structural and geotechnical purposes, in badly broken formations.

Consistent and Accurate Orientations

Based on modern gravimetric sensors, Reflex ACT measures independent components of the earth’s gravitational field, and correlates this information to accurately determine bottom of hole and the original position of the core sample in the substrate.

Reflex EZ-AQ®

Reflex EZ-AQ® is a magnetic surveying instrument for AQ-sized boreholes.

For special needs

The diameter of Reflex EZ-AQ® is only 25 mm, which permits measurements in boreholes from AQ-size and upwards. Reflex EZ-AQ® may be equipped with a heat shield and a heavy duty pressure barrel, which allows the instrument to withstand an ambient temperature of +177C/+350F for ten hours and a pressure of up to 20,000 psi.

Reflex EZ-Dip®

Reflex EZ-Dip®is a small electronic instrument for dip measurements.
