I can't seem to establish whether it's possible to adjust the height of the saw blade! That one I linked to on Tescos, clearly has a bevel/angle adjustment knob, but I can't see anything else (doesn't mean to say it hasn't got one).

Does your Wickes tile cutter come with a blade depth adjuster? (presumably it's very noisy too?)

Edit: BTW John...I can't find one of these for a tenner anywhere on Ebay?
