Mammoth teeth are horrible to work. They fall apart. Keep the super glue handy!

If a drill breaks out of a brittle material, try countersinking the spot where the drill will come out.

Make sure the OD of the countersink is bigger than the drill. The goal is a non-sudden transition. It doesn't have to be a lot bigger.

Thanks. All good advice. Fossils should be here this week. Looking forward to this material in handles.
