If its a blind hole - sometimes you can use a thread tap.
Just keep on turning it as it bottoms out in the hole and the dowel will thread its way up the tap, and out.
Use some PB Blaster spray ahead of time, to start with.
Its one of the ways we get old starter bushings out of bellhousings on older model VW Diesels.
They are a pressed fit into a blind hole of an aluminum casting.
