Hole saw adapter with round shaft for expanding an existing hole

Hole saw adapter with round shaft for expanding an existing hole.

If you need to expand an existing hole, this adapter will be able to help because it makes it possible to put 2 x hole saws together.

First, you mount the hole saw for the new hole on the hole saw holder 60308348, then you replace the center drill with the adapter.

Instead of the center drill, the hole saw from the existing hole is used, it is mounted on this adapter (60308430), it means that the hole is centered correctly.
