Product profile : 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 which these bits are able to handle 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 from a drill hole.
 
FIT provides two types of T.C. Core Bits : 
Standard T.C. Core Bit 
Unless otherwise specified, the octagonal inserts is the standard for this type of T.C. core bits, with various sizes according to different bit kerf widths.
 
Carbotec T.C. Core Bits 
Carbotec bit is another type of tungsten carbide bits, consisting of tungsten carbide fragments fused together to form a crown with multiple cutting edges. They are particularly effective for cutting in formations which are highly fractured or contain loose pebbles. Carbotec T.C. bit causes less vibration and offer better core recovery than standard T.C. bits.
