DC30 hardfacing allows for double the hardfacing application to the critical areas of the steel teeth bits cutting structure.
Proprietary bearing machining processes support longer bearing life in all EVEREST products whether open or sealed bearing.
Carbonate grade TCIs reduce or eliminate the microfracturing induced heat checking of the carbide inserts associated with drilling carbonates.
