Norton Expert Turbo Jet Blade 230 x 5 x 22.23mm
Haven't used this yet. Bought to replace the much cheaper Erbauer one as that started to struggle with cutting stone paving slabs.
However, despite being listed as 5mm thick (the reason I bought it) this Norton disc is more like 3mm thick.
Will review again once used.

Not good enough
I bought this because Norton have a good name and was expecting no trouble cutting some bricks. The first four went ok, then after that the disc just tried to burn it's way through instead of cutting. I ended up doing the rest of the cutting using a cutting disc for my 4.5" grinder. It would probably be ok for softer materials.

The best turbo blade
This blade did what it said it would, it cut block paving blocks very fast with very little chipping of the edge of the blocks, also lasted a lot longer than other turbo type blades i have used in the past, Worth paying the extra to get a great finish and long life out of the diamond blade.
