I just had a screwfix special offer brochure in and it had the a QEP CLINKER heavy duty cutter for £70 from 109.99. I am sure Bubblecraft has one and says they are really good. Not had one myself but its seems a bargain.
It is a great cutter. It's my main flat bed cutter & never had any problems with it. Will cut all ceramics & porcelains & a few natural stones. Granites, conglomerate marbles & slates do snap ok with a good wheel but have a very slight kick at the end but can be tidied up with a wet saw or grinder.
It's a bargain at that price. I might even get another before the end of the tax year lol
