Myconsumables for cutting discs seem to last a good amount of time and are pretty good on price.

I'm often using it to cut round bar so maximum depth is useful. Both of mine are 115mm's but I am tempted to get 125mm's and make a bigger guard for it. The parkside grinder has a low rpm anyway.
Actually been finding my mini 3" grinder has more usable depth due to the smaller centre bolt and body and its not that much slower.
Faithfull any good? They have a tin
Parweld?

Please could you suggest a brand or supplier? I had a look but couldnt see any listed as zirconium, only for flap discs.

I use Rasta discs and flap wheels atm, its a local supplier Weldtech.
Unfortunately they seem to be out of stock of nearly everything right now, but usually they have two types of slitting disc, one called formula 1 that has zirc in it. Not sure how much longer it makes them last, but they are very good.
We buy klingspor kronenflex at my day work and they seem to be ok, good value for money.
I wouldn't touch a faithfull tool, cheapest of the cheap. Parweld not sure about either. If you're looking for cheap, myconsumables seem to be worth a try.

I notice Rasta are a SGA brand unfortunatly, who have had enough of my time and money (worked for them once).
What about these?

I had some Parkside metal cutting discs from Lidl the other day but havn't tried them yet, Parkside stuff is usually middle quality.
You don't say what you intend cutting but if it is thin guage you need to secure it well as if it vibrates while cutting it will turn discs to dust in no time.

A mix of things, I dont do much sheet and where possible I now prefer the mini 3" 12v grinder anyway. So for me, the 4.5" grinder comes out for chopping 30-70mm round bar. The recent lumps were 50mm stainless when the bandsaw went off..
I have some 2.5" chromed hydraulic bar, I want to chop a lump off next week. I would bore it out first but its far too long to go in the lathe.

Flexovit klingspor, dronco, I've found to be decent. Generally I go for whatever named brand works out cheap. For the professional, time is mone of course. For hobbyists like me, money is money and it's usually tight - an extra few cuts, or seconds shaved off doesn't make much difference to the sort of stuff I do.
Likewise if the discs last half as long but cost a tenth of the price, I'm fine with that, as long as they aren't complete rubbish.

favourites are klingspor. been using them for over 10 years never had one break (as an hobbyist but did a lot of cutting during my cortina restoration
) 
https://www.ebay.co.uk/itm/266427030268?var=566239108273 tried parweld a few years ago as cheaper and wore down quick and seemed to just sit on the steel wearing away rather than cutting (on 1mm steel 
) and had 2 shatter. reminded me of clarke 3mm cutting discs from years back before 1mm were available

I also use hydraulic ram steel for making pieces on the lathe and don't have any problem cutting with the band saw but maybe what I have has lost more chrome than your pieces, my blades are from Tuff Saws as a member here recommended I get. Would grinding the chrome off where you are cutting help?
I find ram steel after the lathe doesn't have a good finish but sometimes needs must.
