NOV® Downhole proudly introduces ReedHycalog® Helios™ Thermal Tough Cutters, a range of thermally abrasion resistant PDC cutters that have been re-engineered from the ground-up.  This leading edge technology has been designed specifically for maximum thermal toughness, combining high-density polycrystalline diamond material with NOV’s patented deep leach technology to significantly reduce cutter degradation and allow the bit to drill considerably further and faster.
