I've got a Vitrex 750 and I've put a Faithfull sintered blade on it, it has a 16mm bore conversion for the Vitrex 750. It cost me about £20 for the blade, it's sintered and cuts EVERYTHING neatly as the blade is quite thin, but it hasn't shown any signs of wearing, since it was fitted last october, and it's done lots of porcelain and stone , the cutter is also very robust desoite how it looks You can get the blade via ebay on the following link http://cgi.ebay.co.uk/Faithfull-FAIDB180CR-Diamond-Tile-Saw-Blade-%d8-180mm_W0QQitemZ110415880370QQcmdZViewItem?rvr_id=&rvr_id=&cguid=fbef82551290a0aad2b6f376febff7e7
