Cutting discs advice/recommendations please

Used Klingspor discs for 11 years every day , working for a multi national company who would only use good quality stuff .

No complaints , last well .

I've used a hundred or so of these - great value for money

    Blue spot cutting discs

If you think blue spot cutting, grinding or flap discs are in any way acceptable in terms of performance or wear, go out and buy some of the aforementioned brand name ones, and prepare to be amazed.

Well I needed some more, so I've given some Dronco's a go.

I've spent some of this weekend being amazed at Derren Brown on telly, looking forward to being amazed next weekend too 

Big brand names do cut better, so use the advice above. For you, it may be worth getting a diamond disc for metal. I've been using the DeWalt one and although slower and noisier than an abrasive it doesn't wear down. The date issue goes away as well. I recommend them as a "backup" for every box for that reason.

In all honesty they are all much of a muchness brand wise. The vast majority of discs I use are ones other people have discarded (when you ain't paying I guess you don't bother once you have used up the first 5mm!) I've used all sorts of brands and I cant see any real correlation. All I will say is the thin discs will cut far better and quicker than thicker discs and usually the bargin basement discs are thicker (ie 1.2mm vs 0.9mm or whatever)

I think the last ones I actually bought came from parweld about 5 years ago. They are still going strong. How long they last depends how you treat them more than anything.

Thanks for all the responses. I've bought a 10-pack of Dronco from ebay for less than a fiver including postage. Cutting will commence once they've been delivered!
