Tungsten Carbide Core Bits (T C Bits), like diamond core bits, drills for cores but use tungsten carbide as its cutting medium. It cuts the same size core as that by a diamond bit & fits into the same size core barrel.
These bits have octagonal tungsten carbide inserts as cutting edge. The quality of tungsten carbide tip has been specially chosen for rotary core drilling to give high wear resistance.
UEW T.C. Bits can be used in soft to medium hard or comparatively less abrasive formations. These can be used as tools for cleaning out casing. These bits can replace the more expensive diamond drill bits when used for drilling in non consolidated formations.
UEW manufactures complete range of following TC Bits as per DCDMA / BRITISH / WIRELINE Core Drilling Standards
