Hi peeps. I found this in my late father's garage, I have absolutely no clue what it is, I figured maybe for cutting holes in wood? or am I mistaken? Any help and naming of it would be much appreciated :)
Thanks!

It's an adjustable hole saw. Usually has two cutters.
We used these in the toolroom to cut holes in thin material, sheet metal and gasket material. With one cutter it has to be used in a mill or drill press. We called it a trepanning tool.

Trepanning tool? You were doing brain surgery in shop?
No, but when asked if it was hard work, we always said, "It's not brain surgery". hahaha (sorry)
I call it a Trepannig tool also. I have trepaned 6" holes in 3/8inch plate with such a tool. Heavy duty drill press, very slow speed with plenty of cutting oil and it is amazing what can be done.

The term that I learned for this type of hole cutter is a fly cutter
Tank cutter - used to cut holes in galvanised iron water tanks - superceded by hole saws and plastic water tanks.... Used with a brace - too vicious and dengerous in an electic drill
Clamp down the work to the drill press stoutly, and do not get your hands within the same time zone!!
I use these often. I will never love them
