Robin and I put in edits at the same time, so I'll add my refs/comments here and reject my version.
I was happy to agree to Robin's removal of "vegetable" for two reasons: (a) none of my JEs has that qualification, and (b) the term is used for a wide range of graters including those quite suitable for cheese (see the Ikea ad link, where a very 3D one is labelled おろし器.) The more traditional おろし金 would struggle a bit with a soft cheddar or mozzarella, but is fine for parmesan.
That said, The kokugos do specifically mention the vegetable grating role.
I'm suggesting an "esp" comment, but I'm not sure it's needed.

おろし金 is quite commonly used to refer to any type of grater (see example above), but if we want to make the distinction, "(vegetable) grater" isn't a particularly helpful gloss.
You wouldn't usually use an おろし金 for carrots, but you would for wasabi and ginger, which most people don't think of as vegetables.
I suggest something like this.

Not really, no. Ever tried grating
cheese on an おろし金? The more 3d
graters sold at ikea are called 
グレーター/おろし器 rather than 
おろし金

I'm sure you could use an おろし金 to grate whatever you liked.
