Plasplugs tile cutters

IIRC, it also has a larger motor which can be run for longer periods before requiring switching off to cool down. My original basic one took its thermal fuse. Which is a bit tricky to replace - it's not like a normal user replaceable fuse.

And the larger cutting wheel allows you to cut thicker tiles.

Not sure what you mean by that. The water sits in a tank, the disc dips into the water for lubrication, cooling and a muddy shower for the operator. Do other tile saws need a runing water supply?

Yes, but you need to give it a good wash to get rid of the sludge so I don't see a drain being a great advantage.

Might be false. How long a disc lasts depends on how deep the diamond edging to the disc is. The bigger one might be going faster (in linear terms) than the smaller one, thus may wear quicker. All other things being equal, like the material being cut.

It leaves you with 67.5 degs, two of which take you round a 135 deg bay. Never seen a tiled bay though.

On some the water from the tank is lost once 'used'. Certain versions of the Plasplugs have a drain channel round the outside of the bed which returns most of the water to the tank.

I've used it to make a tiled octagonal "cakestand" for someone who sells wedding tiaras.

Well, there you go. A vital setting on any tile saw.

So to summarise so far:

It's worth getting the Pro version for the better motor but the drain and 22 deg mitre are not worth fussing over?

When I read the box in the shop they both said they would cut up to

It could be that they all use the same motor these days - my comments were on the ones I've bought and used. However, it would seem strange to use the same motor/gearbox but different sized blades. The other clue would be the power consumption.
