It seems like you're looking for information or assistance related to a Hilti drill bit or drilling a hole with specific dimensions. A 14mm by 13mm dimension isn't a standard drill bit size, but it could refer to the size of the hole you want to drill.
To drill a hole with those dimensions, you would typically use a larger bit to create the initial hole, such as a 14mm bit, and then a smaller one, like a 13mm bit, to reach the final size. Make sure to use appropriate drill bits for your material and application, and always follow safety guidelines and instructions provided by Hilti or other manufacturers of your tools.
If you have more specific questions about Hilti drills or drilling in general, please provide more details, and I'll be happy to assist you further.
