What Drillers need.....
v' Quality Design.
v' Increased production.
v' Better cost per Meter.
Impregnated Core Bits
Diamond impregnated core bits are at the forefront of exploration technology.
Premium quality diamonds are embedded in an infiltrated or sintered matrix which during the drilling process erodes and exposes the diamond particles to cut the rock formation.
Variances in matrix metallurgy allow the customer to select a Series bit to suit the rock hardness parameter being drilled.
Impregnated Depth
This refers to the thickness of the crown area of the matrix. Industry standards and customer satisfaction have been the key drivers in demanding value for money in Crown design, and it all starts with crown Height.
CoreEx offers crown designs and Matrix height to suit your needs.From 9 mm through to 20mm.
Other customer defined impregnating depths are also available upon request.Unless otherwise stated, a 16mm impregnation depth is supplied as standard design.

TSP & PCD Bit TSP Type
Description
Thermally Stable Polycrystalline bits that usessmaller triangular and cubic shaped cutters that are composed entirely of micron-sized syntheticdiamond particles.
PCD Type
Polycrystalline Diamond Bits that use larger cylindrical shaped cutters that consist of a layer of micron-sized synthetic diamond particles that are mounted on a tungsten-carbide substrate.
Geotechnical bits are recommended for use when drilling relatively soft, abrasive, unconsolidated sedimentary formations that are not effectively drilled by surface set diamond bits. The formation types may range from very soft clay, gypsum or talc to harder types of sandstone. The difference between the various types of geotechnical bit is in the degree of cutter exposure and the density or number of cutters mounted on the face of the bit.
Surface Set Bits
Surface set diamond bits can be used with any type of core barrels. By varying the diamond grade, size, quality and matrix hardness and crown shapes, the user can satisfactorily drill and core hard and homogeneous formations.
To avoid excessive matrix wear at the leading edge of each segment, tungsten carbide inserts are fitted on each side of the waterway. This kind of bit can not be used in broken or loose formations.
Down Hole Motor Bits
Bullnose Bits and Reamers
CoreEx manufacture Down hole motor bits for use with Directional Drilling Tools. These tools come with industrystandard threading (BW Pin on N Series bits.... NW Pin on H Series bits).
A Full Range of Matrix series is available to be manufactured to suit your needs.Bullnose Bits and Reamers are also available to assist in maintaining hole deflection during navigational operations.
Casing Shoes & Ream Over Bits
CoreEx manufacture industry standard Casing Shoes.
The inner diameter of the casing shoe is sufficiently large to permit free passage of drill bits and core barrels in corresponding sizes.
CoreEx can deliver quality Ream Over Bits (Shoes)to enable Drillers to recover Rods or Casing which may be Encumbered by adverse ground conditions.
Ream Over Bits are available in sizes designed for the following applications:
For reaming over Standard Gauge rods..(N, H and PHD/HWT Wireline Drill rods).
For reaming over Standard Barrel components ( with Standard Gauge Reamers in use).
For reaming over increased Gauge Barrel components ( with Oversized Reamers in use ).
Regular & Adaptor Coupling Reamer Shells
CoreEx design and manufacture Impregnated and Surface set reamer shells with optimum tungsten carbide and polycrystalline gauge protection toensure your drill hole remains in gauge.
CoreEx offer our customers a range of different styles to suit your needs. From Standard length, through to our Triple length design, each Reamer will maximise drill string stability.
Impregnated Reamers…..These are made with high-quality synthetic diamond and PCD wear pins, with Industry-standard spiral waterways for improved stability and increased flushing capacity. Single and Double padded designs are also available.
Surface Set Reamers…..These are set with specially selected diamonds and PCD wear pins to facilitate effective flushing with a view to extended wear and longer service life, providing an excellent economy.
Oversized Reamers are also available in N, H and P Wireline sizes. Designed to increase hole annulus and to reduce rod torque in the hole.
Adaptor & Locking Coupling Reamers……Available in all sizes and designs. Specifically for maintaining core barrel stability and enhancing drill hole direction, whilst reducing rod string vibration.
Accessories
Carbon Guide Plugs are used in transitioning Bits across an IN – Hole Wedge when Directional Drilling.Plugs can also be utilised to prevent inner tubes being filled with Mud or debris in poor ground conditions during rod string descent.
Carbon Guide Plugs
Reamer Gauges
Gauged steel rings are designed for drillers to keep a check on the Reamer gauge to ensure that hole annulus is maintained throughout the drilling process.All Gauges are marked with size for measurement reference. (Excluding Oversized product).
