Bond / Service life
If the cutting efficiency of the tool drops off sharply after only a few drilling operations, the bond you have chosen is probably too hard for the material you are working on. You should therefore use a softer (more efficient) bond.
 
Bond / Service life
If the diamond coating of a core bit / disc only lasts a short length of time despite good cutting efficiency, the material you are working on is probably too abrasive for the bond you have chosen. It would be wise to use a tool with a harder diamond bond.
 
Drop in drill performance
Possible causes of a sharp drop in drill power during work are excessive advance, eccentric or non-linear operation. The drill may also have insufficient power.
 
Sharpening stone
If the cutting efficiency of diamond tools is no longer adequate, you can improve it significantly by briefly dry-drilling/dry-cutting in a special sharpening stone. The cutting efficiency will diminish if the tool is used on materials for which it is not intended. Insufficient cooling may also be the cause.
