Guys,
Just checking EBay and saw the supplier I have used for blades for my D2400.
DEWALT DT3733 254 X 25.4MM DIAMOND TILE CUTTING DISC | eBay UK

I know many people are directed to other suppliers and makes, but this blade is IMHO is the best blade available going.
Yes I have spent Ģ140 on recommendation of popular choice, but this blade is unbeatable pound for pound.
Now itīs even cheaper.
Want great clean cuts and no chipping on Porcelain, GET IN THERE!
Save yoour old blade for the ceramics and itīs like laser cut.
