1

Leaching Technology for 750°C+ Resistance

Precision cobalt-leaching removes thermal expansion risks, preventing micro-cracking in extreme downhole heat.
2

Optimized Interface Against Spalling

Non-planar interface disperses residual stress, drastically reducing cutter delamination in fractured formations.
3

Premium Powder & HPHT Sintering

Ultra-high pressure sintering creates maximum diamond density, delivering extended wear life and higher ROP.
