Sir Ramic, the saw is a no-name jobby bought cheaply on ebay. It's got 'Made In China' all over it, and it was bought from an Asian seller here in Australia. Even though the quality might sound dodgy, it is constructed pretty solidly, and will suit my small job pretty well.
Dave, good question, but yes - using water via a small pump located in the tray underneath. The blade gets good water coverage - I don't think its an issue with overheating.

After canvassing all your replies, I suspect I've installed the incorrect blade for the porcelain tiles I'm cutting. It's quite a thin blade, and it's got quite a bit of flex in it. I'll procure the correct blade and see how I go.

Cheers, Darren.
