As the dings normally only constitute a few percent of the surface of the taper, I would remove them with a file or a touch from a grinding stone  in a Dremel or similar.

This will preserve as much as possible of the original surface for maximum accuracy and grip.

I’ve used those flat diamond sharpening “stones” (they are actually metal plated with diamond stuff) to true up bruised tapers. Just keep gently rubbing until all the surface appears to have been touched. Before I had the stones I used fine files to do the same thing.

Agree with the others, a very gentle use of a fine file or stone/diamond lap in the dings only should be all thats needed. Fingernails are incredibly sensitive in gauging progress when passed over things like these.

I personally would be wary of trying to be too agressive as you could end up make things worse.

It’s the sort of job I would put on the side of the bench and just have a go every so often when you’ve got a spare few minutes, rather than find it getting tedious because of the number you’re trying to do in a big batch!

Treat it as therapy – nice bit of straightforward, calm work, not much thinking?

The Eze-Lap branded ones seem particularly good quality, and the version with a handle suits this sort of work very well.

These tools are known for their quality and durability, making them suitable for a variety of jobs.

Another approach is the ‘burr file’ – a fine file with the tops of the teeth ground off. This will remove the tops of any upstanding burrs but not damage the surrounding undamaged area.
