Tungsten carbide is feasible for medium to hard rocks, including sandstones, limestones, dolomites, tuffs, granites, etc.

• The high grade tungsten carbide has relatively high intensity, hardness and wearability.

• Floating-seal subassemblies of good quality ensure the cutter’s proper working performance submerged.

• Precision bearing enables the cutter’s flexibility of performance even under extreme drilling condition.

• Advanced and strictly-controlled engineering process provides sure guarantee to the indisputable quality of the cutter.
