Are hole saws readily available in 54 and 82mm diameters?

I'm fitting ETB 80 52 and 80mm gauges to my dash.

Cheers
Nick

Use the 52mm and 80mm hole saws that are available.

They are sized to give clearance over their nominal sizes so your gauges will fit through the holes you drill with a 52mm and a 80mm hole saws.

you need one of these

dont you need to cut the holes a little bigger to allow for th evinyl or leather that needs to go through?

Hole saws always wobble and cut a slightly bigger hole than the nominal size.

cheers guys - checked what sizes my dad had at work and found a 50, 51 & 52 so will try all 3 and see which gives the best fit. Will have to buy a larger one though.
