Grinding wheel review
On PM, someone made a passing remark about 3M Cubitron II grinding disks lasting the longest....
So I did some googling and found some in AUS. https://www.ebay.com.au/itm/252944739652
Pretty expensive I thought, but if they last, then it might be worth the expense for a trial....
I've been using the ONE disk for about 2 months now. Some pretty heavy work (cleaning up plasma severance cut steel plate, cleaning up welding beads etc etc. Giving it a pretty hard time.
The result so far is that it seems to have reduced very little in thickness and NOT AT ALL in diameter. I'm pretty amazed. It seems to cut MUCH faster than cheap grinding disks and with less force applied to the grinder.
Just thought I'd pass that on - only because I'm impressed myself.
Anyone else ever used these?Cheers, Joe

No, but now I'm interested!
Thanks Joe.Girl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.

Yeah these things are great, I go through one of these every few weeks. They don't clog up like the standard ones do. When they are new you need to be very careful as they can take off more than needed. They are expensive, but work pays for them.
When at home I just use whatever is cheapest as I don't do a lot of grinding here.
If you get a chance try out one of these! https://www.3m.com.au/3M/en_AU/compa...3241514&rt=rud

Yes they are exceptional discs and flap wheels wait till you get some linishing belts though they are the next level they never clog up always sharp right till the end

I haven't used a flap disc in about 10 years probably, don't think work even stocks them. I don't really see the benefit in them.
Yeah finishing belts would be a good thing I reckon, wouldn't mind trying some out.

Hi Joe, Guys,
I've a number of those 3M disks, that I got a while back. So far I've never used them, I'll have to get them out and have a look at them.Best Regards:

I just found because of the curved design that it was easy to removal material where not needed. I much prefer an orbital sander and rolocs for finishing type work.
By the way for anyone who hasn't used these things before, they work great for paint and rust removal. 5 x 125MM POLY STRIPPING DISC WHEEL PAINT RUST REMOVAL CLEAN METAL ANGLE GRINDER | eBay

I can't say I don't use grinding wheels, they're handy for inside corners & areas where a flap disc would be destroyed; the downside is they can be expensive; lately, I've been using these which aren't too bad...

I'm not sure what you mean by the curved design? They're round of course, but are either flat or with a bevel on the working face. They do tend to wear roundish, however I've never found that an issue in hitting the correct spot.
I agree, the stripping disks are also good, but I find they don't last as long, and generally aren't as aggressive as a typical flap disk (depending of course on the grit used in each).

The ones I used had a bevel or maybe they were just worn out. I should try some again. Smith & Arrow have some Ceramic ones. https://www.ebay.com.au/itm/5x-125mm...7pUOl01uReh3RA
