2) Reaming Shells

The reaming shell is part of an overall drilling system that includes a core bit, a core retrieval device (core barrel assembly), the drill string (rods) and the drill rig itself. The cutting media on the reaming shell may take the form of natural drill diamond on the I-Series type, a combination of synthetic diamond and natural drill diamond on the Heavy Duty type, or strips of tungsten-carbide deposits.
This group of products is used to maintain the critical hole diameter and to stabilize the drilling system in the hole during operation. The reaming shell is part of an overall drilling system that includes a core bit, a core retrieval device (core barrel assembly), the drill string (rods) and the drill rig itself. Its key function is to create an accurate sized hole with the precise, stable specific diameter. The cutting media on the reaming shell may take the form of natural drill diamond on the I-Series type, a combination of synthetic diamond and natural drill diamond on the Heavy Duty type, or strips of tungsten-carbide deposits.
Product Descriptions:
Reaming Shells
This economical diamond set reaming shell is available for use on all conventional and Wireline core barrel assemblies with drill hole sizes of up to 8 inches (203 mm) in diameter. The IDP reaming shell is manufactured with a full matrix body gauge ring that is cast onto the steel tool body for maximum bond strength and tool integrity. In addition, the reaming shell gauge ring features spiral waterway canals that both effectively clear the bit cuttings and provide full 360 degree hole contact with the matrix body gauge ring.The setting on the gauge ring is a combination of mechanically rounded 'P3' Grade natural drill diamond in the size range of 20 to 35 stones per carat and seismic grade tungsten-carbide wear pads that are cast into a tough, abrasion resistant matrix body. The IDP reaming shell is recommended for use in light to medium duty applications where the formation conditions are relatively consolidated and non-abrasive. Although hard-metal strips that are used to armor coat the steel tool body are normally not provided on reaming shells, this option is available at an additional cost.
Heavy Duty Reaming Shells
This "Heavy Duty" type represents IDP's premium line of reaming shells. They are intended for use primarily on Wireline core barrel assemblies with drill hole sizes of up to 6 inches (152 mm) in diameter.
A tapered leading edge for ease of movement down the drill hole. Placement directly adjacent to the male thread connection to reduce the possibility of abrasive washout between the shoulder of the drill bit body and the gauge ring of the reaming shell.
The IDP "Heavy Duty" reaming shell is recommended for use in the most difficult applications where the formation conditions are highly unconsolidated and abrasive. As a standard feature, all IDP "Heavy Duty" reaming shells are supplied with hard-metal strips on the exposed outside diameter of the steel tool body. These hard-metal strips are composed of micron sized tungsten-carbide particles that are suspended in a metal alloy and are used to armor coat the steel tool body in order to prevent premature wear.
Stabilized Reaming Shells
IDP's stabilized reaming shells are available for most wireline core barrel assemblies in the 'AWL' (Ø 48,0 mm) to 'PWL' ( Ø 122,6 mm) size range. Their purpose is to assist in minimizing the degree of drill hole angular deviation in target or deep hole drilling situations.The term “set diameter” refers to the dimension of the matrix body gauge ring diameter on which diamonds (or synthetic PCD particles) and tungsten-carbide elements have been physically set in order to preserve this dimension during drilling. The specifications for set diameter tolerances to which IDP manufactures reaming shells are given in the following tables.
3) Casing Bit & Casing Shoes Bit
Impregnated Diamond Casing Shoe Bit
Home Products Casing Bit & Casing Shoe Bit Impregnated Diamond Casing Shoe Bit The impregnated diamond casing shoe is the most commonly used as it has the widest range of application and is generally the most efficient tool for advancing casing through overburden layers. IDP manufactures impregnated diamond casing shoe Bit that may be used with all sizes of standard casing tubes. The basic construction of these casing shoe Bit features a sintered powdered metal crown that is fused to a steel tool body or shank. The powdered metal crown is composed of two layers: the “matrix” layer which cuts the overburden and the “backing” layer which connects the matrix layer to the steel tool body and serves to support the gauge diameter protection hard materials.Casing Shoe Bit
This economical impregnated diamond casing shoe Bit is available for use with all standard casing tube sizes and a limited number of Wireline drill sizes. The IDP ‘casing shoe Bit is intended for use in applications where the casing tubes are to be permanently left in the drill hole.
IDP casing shoe Bit are supplied with :
§ Flat-Face (Style ‘F’) crown profile.
§ Regular (Style ‘W’) waterway configuration.
§ 0.12-inch (3 mm) diamond impregnation depth.
The matrix layer on all sizes of IDP impregnated diamond casing shoe Bit contains natural diamond crystals that are uniformly distributed and embedded in a powdered metal bond. Unlike the matrix layer, the backing layer does not contain diamond crystals distributed throughout its volume. The backing layer is also composed of a powdered metal bond material and has good wear resistance properties. The exposed outside and inside gauge diameter surfaces of this layer are set with a combination of natural mined ‘kicker’ grade diamond and tungsten-carbide wear pads. These gauge setting materials assist in maintaining the critical gauge diameters throughout the life of the shoe.
SurfaceSet Diamond Casing Shoe Bit
As the name suggests, this style of casing shoe Bit differs from the impregnated type in that they are set with a single layer of natural drill diamond in a pre-determined pattern on the working surfaces of the tool. Surface-set diamond casing shoe Bit are recommended for use when drilling relatively soft and abrasive formations such as sandstone or limestone. The diamonds are embedded in a powdered metal matrix body tool crown that is fused to a steel tool body. Unlike impregnated diamond casing shoe Bit where the controlled erosion of the powdered metal tool crown is desirable to expose new diamond crystals, the metal bond matrix used for all IDP surface-set diamond casing shoe Bit is extremely tough and wear resistant. The function of the tool crown matrix body on a surface-set casing shoe Bit is to securely hold the diamonds in place throughout the operational life of the tool. IDP manufactures surface-set diamond casing shoe Bit that may be used with all sizes of standard casing tubes.
Tool Configuration
All IDP surface-set diamond casing shoe Bit are supplied with a semi-round crown profile and a Regular (Style ‘W’) canal type waterway configuration.Diamond Quality
Unless otherwise specified, the tool face of all IDP surface-set casing shoe Bit are set with economical ‘A’ Grade natural drill diamond. Any of the other standard IDP diamond grades may be substituted on request. In addition, the outside and inside gauge diameter surfaces of all IDP surface-set casing shoe Bit crowns are set with a natural mined ‘Kicker’ Grade diamond to assist in maintaining the critical gauge diameters throughout the life of the shoe.Diamond Size
All IDP surface-set casing shoe Bit and rod shoes are supplied with one of three standard diamond size ranges, namely 25, 50 or 75 stones per carat (SPC). The use of diamonds smaller than the 75 SPC range is not recommended for surface-set casing shoe Bit. While it is possible to specify diamonds larger than the 25 SPC range for use on surface-set casing shoe Bit, consideration must be given to kerf width constraints in allowing for sufficient diamond coverage when using larger diamond crystals.Tungsten-Carbide Casing Shoe Bit
This type of casing shoe Bit uses seismic grade tungsten carbide as the cutting media. Tungsten carbide does not possess the hardness of diamond and as such has a limited range of application as a drill tool cutting media. Tungsten-carbide casing shoe Bit are however a very cost effective means of drilling through softer unconsolidated formations.Set Diameters for Casing Shoe Bit
The term “set diameter” refers to the dimension of the outside or inside diameter of the matrix body on a casing shoe Bit crown on which diamonds and/or tungsten-carbide elements have been physically set in order to preserve this dimension during drilling.

4) Diamond Drilling
The main technology in diamond drilling equipment is its diamond bit. The diamond bit is made of a soft metallic matrix. The industrial diamonds are scattered throughout the matrix to provide diamond bit. The reliability and strength of bit depend on the matrix. This bit is mounted on drill which is connected to rotary drill system. The diamond bit is designed for the specific rock type according to requirements or its application. While choosing diamond core drilling machine, diameter of core bit defines the specifications of the machine. Generally, larger diameter core is expensive than smaller ones. The core bit sizes of diameter NQ and CHD 76 are more commonly used. However, many other sizes of core bits are made available according to requirements.
