PDC drill bit from GeoGem Limited

A wide range of full hole PDC drill bit designs are available and are used in numerous applications within the civil engineering and mining industries.

PDC bits are manufactured with a tungsten carbide crown imparting a much superior wear resistant than equivalent steel headed bits.

Specially developed dome-shaped cutters are incorporated into majority of drill bits due to this type of cutter having excellent impact absorbtion than standard flat cutters. Each PDC cutter has a built in side and back rake, which cuts more evenly and with less torque and vibration. Thus the dome cutter is less susceptible to heat damage and does not suffer edge chipping to the same extent as the flat cutter.
