FAQ

Problems & solutions for drilling with diamond core bits

1.The core will not drill
• The material is too hard for the core bit application range: use a specification suitable for the material in question
• The diamond impregnation is blunt: sharpen the tool with a grinding stone or abrasive material
• Speed too high: reduce speed
• Water flow too high: reduce water flow
• Excessive play of the drilling stand guides: set up the drilling stand
correctly, or have it repaired
• Drilling stand not properly anchored: improve anchoring, use suitable dowels
and a thread rod
• Insufficient machine power: check the motor speed and slip-clutch. Use a more
powerful drill
• Drill motor running, but core bit not rotating: low contact pressure so that the slip clutch is not engaging. If the problem reoccurs, have the drill repaired

 

2.Excessive wear of the diamond segments
• Insufficient flow of water. Drilling sludge sharpens the diamonds and also wears them down: increase the water flow
• Feed / contact pressure too high: reduce feed
• Drilling material is very abrasive: use a harder core bit segment specification
• Excessive motor power: adjust the motor speed to reflect the core bit diameter
• Core drilling system has too much play, causes excessive vibrations: check and correct the settings.

Tighten screws, effect repairs as needed
• The drill stand is not properly anchored: improve anchoring, use adjusting screws (make sure they are adjustable).

Use the right dowels and threaded rods or the material that you are drilling
