Giltha Core 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 Before the drill is withdrawn from an incomplete hole, let the tool run for a short time at the bottom of the hole without removing any material.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.

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.
