Technical Selection Matrix

Precision drilling performance relies on matching matrix hardness to aggregate Mohs scale ratings and motor horsepower.

Hard Aggregates / Heavy Steel

Employ softer cobalt-bronze bonds (ZENESIS V or Geared Turbo) to ensure steady diamond renewal when striking Grade 60 rebar.

Abrasive / Low-PSI Materials

Use hardened tungsten-carbide matrix bonds (X300 Asphalt / X300 Masonry) to counter slurry erosion and protect diamond retention.
