    Thin cutoff discs - any difference between brands

    Been going through a few of the 1mm cutoff discs in the angle grinder lately, so thought I'd better stock up before I ran out.

    Having a quick look online, for quantities of at least 10, the price varies from around 60 cents per disc to around $2.50 for decent name brand ones (like Flexovit). There's Bosch ones in the middle for $1.50/disc.
    Pricing is for 115x22 1.0mm discs.

    I'm not too fussed on the actual price, just want to get value for money.
    Has anyone used a few different brands and noticed much difference in performance or life?

    I use about a box of 25 of them (125mm) a month and have tried most. I keep coming back to the "Pferd".

    I buy from The Bolt Shop and they work out about $1.80 each or thereabouts.

    I recently purchased 2 tins of the Bosch ones, never again, they wear way too fast.

    Cheers,

    Mate I always use flexovit ones however the Bosch ones are ok as well. Definitely stay away from cheap ones as I have seen them fly apart and they usually wear down much quicker as well. I've also had several cheap ones spin the center out when you get a slight bit of a jam.

    I've tried a few brands, cheap ones are just that - cheap and crap, they wear out quick and bust up. While pferd are ok, I find that they still wear more quickly than Flexovit, they are also more prone to explosion. The pferd rep once told me about their "new" and fancy air holes that make them last better because they dont get as hot - maybe it works but I can't see it.

    I stick with Flexovit where I can, I find them the most robust, quick and nice to use. I mostly use 125mm discs.

    I've also found the same with 6mm grinding discs. Cheap ones are rubbish.

    Be aware if you are stocking up - grinding discs absorb moisture and are then very prone to explosion. So either keep them pretty well air tight or don't stock up too much.

    At the end of the day I think it's a preference thing - I've seen guys swear by pFerd and then there are the others that hate them and same with Flexovit....

    I use either pferd or flexovit and have not noticed a difference between those two. I would steer clear of ebay for any cutoff or grinding discs. The cheapo ones are absolute rubbish, seem to be made of compressed dirt.

    Stick with the suggested.
    Cheapies tend to explode and the fragments bloody hurt!!!

    I buy the Makita 12 pack of 1.2mm x 125mm discs from bunnings for about $17 - they work out to just over $1.40 each and last better than the Bosch ones I tried. I did use some Flexovit ones and felt no difference between them and the Makita - I just find the Makita tin more convenient, as Bunnings here only stock the 2.5mm discs.

    The small ones do hurt, particularly with no guard on...

    Been using Makita bulk tin.

    I'm trying out the diamond edged cut off discs, after having them pointed out to me by the shop when I asked is there any new technology. Packaging says they'll last a zillion times longer than regular discs. The advantage will be that the disc does not reduce in diameter to any extent. They do cut a wider slot though.

    Thanks guys - will definitely steer clear of the cheapies then.
    Good point about them absorbing moisture over a long period. I hadn't considered that.

    My last lot were the Makita bulk tin from Bunnings and have lasted pretty well. Had the odd jam that ripped a piece out of them but they didn't break up/explode and lasted pretty well so I was also reasonably happy with them.

    Think I'll grab another tin of those but also pick up a couple of the Flexovit ones when I'm at the steel supplier on Saturday and see how they compare.

    Out of interest, I just came across this video which reinforces what has been said about the Flexovit discs. They crap on a bit, but at the 2min mark there's a nice comparison of cutting speed and remaining disc after 15 cuts in 12mm rebar.
