Cool Edge Series
Features
A single set cutting structure with backup redundacy for extended longevity.
Diamond-focused hydraulics for improved cutter tip cooling.
Nozzle orientations facilitate chip-braking during initial rock removal.
The medium cone profile and gauge configuration promotes stabile lateral trajectories.
Impact dampeners protect diamond cutters during transitions between interbedded formation layers.
