That is a really hacky "solution" to a problem that is easily solved by using purpose-made brass and plastic bits.

Plastic bits have a 60deg point to eliminate this problem.

Brass cutters have a different rake and other slight tooling changes to keep from catching.

Sheet metal bits have no spiral flues, or very short ones, to avoid this problem.

Not to mention that proper setup and material/tool holding should make this a non-issue in the first place. I would never put a thin piece of plastic in a vise like that, it would be clamped or screwed to a piece of wood or metal that is then clamped or placed in a vise. Working around one bad practice with another bad practice is not a good plan.

Just because some people consider something 'common practice' does not mean it is the safest, or 'right' way to do things.
