Looked at these on SF and the reviews are not good - flimsy etc.

At work we had single-sided one that worked well but it was made 'in house'.

Any recommendations for a good one, please?

What size hole, wood, steel, thickness?

For wood you might like to look at "expansive bits".

These look good - I might get one - but go up to 76mm dia.
Hole saws go higher but 102mm (not quite big enough, so some filing needed)
then to 114mm (too big!).
I have hole saws going to 70mm so I'll get some bigger ones then make do and
bodge!
