Frequently Asked Questions (FAQs) in Core Drilling or hole cutting
What action do I have to take if the core bit gets stuck?
If the core bit gets stuck, switch off the motor. Inspect and carefully take the appropriate action to remove the cutter.
What do I have to change if core bits are breaking?
Check whether the core bits are still sharp. The guides must be set to have no play on the machine. If this isn’t the case, please send your tool to customer service. Reduce the feed force and change the speed if possible.
What should I be aware of when drilling?
Position the drill with care and drill through in one go wherever possible. Don’t switch the tool off during drilling, as doing so could cause the core bits to break loose. Before the drill is withdrawn from an incomplete hole, let the tool run for a short time at the bottom of the hole without removing any material. This will break the chips forming at the bottom of the hole. Always withdraw the drill from the hole with the tool running clockwise.
How can I forestall the core bits from becoming blunt or overheating when drilling?
Maintain a consistent water pressure to cool down the core bit.
What should I do if the core bit is chattering?
Check whether the core bit is still sharp. The guides must be set to have no play on the machine. If this isn’t the case, send your tool to customer service. Carefully increase the feed force until the chattering decreases or change the speed if possible. Use caution as too much feed force may result in the tool lifting up.
