Fixture table hole drill jig

What size chamfer should I use after drill all my holes?

You can choose, it’s not a critical dimension. It helps prevent hole deformation and clamp pin damage. The thickness of the table top comes into play also. A thin top don’t recommend going very deep.

My table thickness is 3/4. I was curious what diameter chamfer I should use. I do not plan to go deep, just enough to create a lead in and reduce the edge.

By the way….. I love your tools. Please keep developing and improving on what you have created.

I use 1 1/4. But something like this might be handy.
