One for all you roofers out there

I'm looking for a supplier for a one hole holing machine, its for making holes in scotch slates, something like a punch.

Is this the type of thing?

(It's described as a 'slate cutter with punch'). If so, it's �44.85 (inc VAT) here:

There's no picture here but the description is the same:

�33.98 (or �39.92 inc VAT).
