Diamond core bit drilling tips & trouble shooting B

Symptom:Loss of diamond segment
Cause:a.diamond core drill bit too hard for the material it is drilling, causing it to pound and fatigue.
           b.Overheating due to insufficient water for cooling and flushing.
           c.Machine setup is not rigid or loose material is in the cut and the bit segment hangs.
           d.Shooting cable, when drilling pre-stress.
Remedy:a.Use a softer bond for diamond core drill bit if possible. Increase motor RPM if possible.
             b.Increase water flow to where slurry is milky and flows easily.
             c.Tighten anchor, check vacuum system for proper vacuum pressure.
             d.Use a bit with more segments, such as a  pre-stressed diamond core bit
