Product Description
Key Features
15mm Standard Crown Height
More Durable & Cost-Saving With a DCDMA-standard 15mm matrix height , each bit delivers 25-30% more drilling footage. It reduces replacement frequency and offers superior durability.
Multi-Hardness Matrices
Full Strata Coverage 18 matrix series (F2-F18 ) to match different strata: soft rock (shale), medium-hard rock (sandstone), hard rock (granite), and ultra hard rock(quartzite). No need to switch bits for mixed strata. Efficient Drilling in Hard Strata New technology matrix for hard strata like quartzite and siliceous rock (Mohs 8-9), increasing drilling footage efficiency by ≥20%.
Forged in Extreme Heat,
Our diamond core bits are born from a precisely controlled High-Temperature, High-Pressure (HTHP) sintering process. This advanced technique fuses premium synthetic diamonds with a specialized metal matrix at the molecular level, creating a supremely dense and uniform structure. The result is a cutting crown of unparalleled integrity—engineered for consistent performance, superior wear resistance, and maximum lifespan in the most demanding drilling environments.
