Before placing order, here is some infomation we'd like to know:
How deep is the project?
What is the rock?
Is it hard, soft or complex rock?
Is the rock very complete, semi-broken or broken?
How is the abrasiveness of rock?
Have you use any other brand before? what is the brand(optional)?
How is the performance previously?
Such as:
Drilling speed?
Meters downhole?
Drill bit working life?
Above questions will help us be more familar with your ground situation, meantime, more accurate and appropriate bit will be provided to you.

Suggestions:
SOFT ROCK FORMATIONS
LOW RPM's
Large diamonds/cutters
Large waterways for better flushing and higher GPM flow rates
Hard matrix for longer bit life

HARD ROCK FORMATIONS
High RPM's
Small diamonds/cutters
Small waterways
Soft matrix to expose more cutting elements
