Use segments one class softer bonded
Segment too big surface
Attach a drill bit with less segments or reduce the rpm
an increase the feed compression.
Too fast RPM!
Use lower RPM.
Drilling in steel!
Use lower gear and reduce feed and increase water
flow.
Drill bit worn out!
Replace with a new one.
Diamond grains pressed into the binding!
Sharpen drill bit in sharpening plate, work with low feed.

Reduce the speed, increase the water flow, re-sharp
the segments
No free cut because of side wards wear-out of
