I want to drill several 3/4" holes for bench dogs in a laminated workbench
top (prior to assembly) that will be 3 inches thick.


Right after posting this message, I discovered Forstner bit extensions.
They are expensive ($29 each). Does anyone have any experience with these?
I am little skeptical of the two allen screws used to hold the Forstner bit
in place in the extension.

I have one. Used it to drill 1" holes into a laminate of oak, walnut,
and purple heart. Worked fine. Not sure about the allen screws in a
hard use environment though.
