Any idea what the dividing sign means in the above?

Cheers

is it not the tolerance? so + or – the number

Edit: sorry didn’t look closely at the left number

surely the + and the – is the tolerance?

As shorty says, what’s it for?

This thread needs Mrs Toast. And a bike, a bear and a rainbow.

Cutting a hole in a worksurface for hob

obelus denotes a range

denotes a range

Naa, its a Hob he said, not an Aga.
😉

At a guess it’s chamfered so the hole is wider at the top or bottom?

is it italian by any chance ?

480 to 490 +2 to -0 tolerance

Not sure what the context is, but it makes no sense to me – unless they’re suggesting a size range between 480 & 490 but then the notion of a tolerance (can’t read it clearly, but it looks like plus2 / minus0) would be nonsense. Couldn’t begin to tell you why they’ve used the division symbol though.

I’d ring them and ask them for clarification; as the drawing’s pants.

It’s a neff hob.

Confused because why not not write 486 +- 6 rather than 480 to 490 +2 – 0

another neff drawing

Why don’t you just measure the hob and see what size of aperture you need that way

Just went with the shorter measurment, fits fine (not in middle front to back because worktops deeper than standard and overhang)

as oli’d said^^^.
Sloping (by 5mm each end of the hole) face to those cuts.
490 measured on top of the opening.
480 measured underside.
Possiblly?
