Product Description

146 Geobor S Wireline Triple Tube Core barrel Diamond Core Drill Bits 


A heavy-duty wireline core barrel enabling 102 mm (4″) diameter cores to be taken in a simple and cost-effective manner. It is designed specifically for air-flush, but foam, polymer and water flush can also be used.

This core barrel has been proven to 2500 metres in depth, with full float capacity, or a dry hole lowering device. With a 6 mm all-round clearance between the outer and inner tubes, full advantage can be taken of both air and foam flush in soft formations.

The core barrel can be used with or without plastic coreliner tubes with the same core lifter and bit setting. The barrel accepts the Craelius SK6L / Geobor S type core bit, or our own equivalent, with a set O.D. of 146 mm and set I.D. of 102 mm. The barrel is rotated with either SK6L 140 mm drill rods or by using good quality PW casing as the drill rod.

The core barrel head is attached directly onto the inner tube and consists of three main parts: the latch assembly, which locks into the locking coupling of the outer tube, the bearing housing, and the inner tube bung. The inner tube bung incorporates a series of "Belleville" springs to allow the core to be broken easily when pulling back on the inner tube, and a float valve that allows the inner tube to be dropped into a wet hole and to control the rate of descent.


Description

Impregnated Diamond Core Bit

Impregnated Diamond Core Bit is made from high-quality synthetic diamond and metal powder which could be used in various types of strata. The best effect is achieved through the flexible design according to the different strata and parameters of drilling equipment.
 
Surface Set Diamond Core Bit

Surface Set Diamond Bit is produced from a single layer of natural diamond setting on the surface of bit crown with hard matrix, and primarily recommended for drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bit. It is also recommended for drilling harder formations, which the available rotary 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 in softer formations due to the greater degree of exposure of the individual diamond crystals. 

Tungsten Carbide Core Bit

Tungsten Carbide Core Bits are designed especially for soil investigation and geotechnical drilling, but also suitable in some applications for mineral exploration. As the tungsten Carbide is softer than diamond stones, the formations are limited in the range of soft or some medium rocks, like the overburden drilling, cleaning of drill holes, e.g. for the removal of steel fragments in hole.

PDC Core Bit

PDC Core Bit has a long working Life, very fast penetration and high percentage core recovery in soft to hard rock formations. PDC bit mostly be used for drilling with air, mud or foam flushing.
