Novice question about ordering a tip

[DJ14.1]

If you have a 13mm. shaft, is it best to order a 13mm tip, or to order a larger one and have it turned down on the lathe? Does it matter?

Thanks

Larger one.

They are usually 14mm. And needs to be trimmed down, both in diameter and length.

They always need to be larger and cut down on a lathe to get a professional installation.
