Picked up some 115mm cutting discs for cutting steel from Wickes (£11
for 5 narrow discs) and noticed that they have 115mm Diamond edged
discs that also claim to be able to cut steel. The Diamond disc is
£25.

Question: Are Diamond discs worth the money? The packet claims that
the speed production because they need changing less frequently. Is
this so? That's not a problem from my point of view but are there any
other (or actual) benefits of using Diamond discs?

A diamond disc outlasts numerous grit discs, cuts faster, and is much
safer. Get one, its that simple. But forget paying £25, they're way
cheaper from toolsatan.

True for concrete/masonry, but for cutting metal (such as the steel
identified by the OP), thin grit discs are much better.

Wickes discs are, I think, Norton - at least they look very much like
them. Anyway, they are good quality. Diamond discs are not all the
same. The quality (i.e. durability and speed of cut) varies
enormously.

I can only partly answer your question, since all the diamond discs I
have used have been for stone/masonry cutting. In the case of those,
there is no comparison - the cut faster, narrower, and last for the
equivalent of tens to hundreds of conventional abrasive disks.

The ones that also cut steel are a newer thing, and I have not tried on
of those for that application yet.

Thanks All

I'll stick with the thin, grit discs for the steel. The ones I have
been using (Wickes) do slice through steel in a very satisfying manner
- and knuckles!

I picked up a 230mm(?) and 115mm grinder set from Makro a few years
back that included a large number of grit discs and one 115mm
'Diamond' disc. Well, I would have got on just as well had I used a
beer mat instead of the Diamond disc!

One thing that is tempting about the Wickes Diamond discs is that they
claim to be able to cut reinforced concrete. I plan to enlarge the
side door to my reinforced concrete garage and the thought of how to
remove the existing lintle has been giving me pause for thought.

The original diamond discs would die very quickly if you tried them on
steel... Unless it was a very cheap crap one, then it ought to work on
masonry. Having said that there are different classes of disc suited to
different types of masonry. Some designed for hard masonry will wear
fast on very abrasive materials like sand stone. Some designed for
sandstone won't even touch granite or porcelain.

My first 230mm diamond disc (a Hitachi one that came with the grinder)
must have cut many hundreds of metres in concrete before finally giving
up in a granite slab a couple of years later!

Yup there are some Makita discs that also make the same claim (in fact I
suspect that this multi material disc is now quite "mainstream")

I bought a £1 diamond masonry disc from Poundland, on the basis that it
wasn't much to lose if it didn't work. I have not had any reason to
regret the purchase.
