Problem with my wet cutter wheel?

[Scott]

I remember doing a granite floor (proper granite) with a mini plas plugs cutter that over heated after 2 tiles. It would take half an hour to cool down enough to cut the next ones. Took 2 days to do the cuts on that floor!

its not normally hard to straighten a steel blade sometimes if it just a little bent just turn it by hand with something just touching as you turn it you will see if a gap appears if it does turn it till its touching again then tap it with something and see if you can straighten it
