And here are the results. All just FYI, but I found it interesting, and in the long run...a cost savings project for my company.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Thanks for the input!

Can you also test cutting aluminum rods and carbon fiber too? I feel like silicon carbide might be a better material for cutting that stuff.
I feel like "gravity fed" might introduce variations on the pressure exerted, which could impact the efficiency/durability of the cutting wheel.

And it was horrible. Slow and VERY loud. Dont get me wrong, this thing would probably be great in a stationary saw doing some production work of some sort...but in an angle grinder for general cutting, we didnt like it all. I also can not attest to the longevity of it, as we only tried it for a few minutes...it may very well last a long time, not sure.
The gravity fed system we used was set up exactly the same for all the wheels. So, even if we were using too much or too little pressure (we think we had it set just right though)...it was equal to all, thus we considered it "fair" for all the discs we used.

We are currently trying to do a similar thing, but for grinding away material (with thicker discs) instead of cutting discs.
Our application is repair welding of Hadfield (manganese) steel, which work hardens easily.
So far we have tested about 6 different types of two brands, it's amazing what differences there are, but we cannot find a test stand that creates the same conditions for each test.
We grind manually for 10 minutes and try to measure the amount of ground away material. Which is a rather questionable test method, I am aware.
We are always open for suffestions!

It's PFERD's CC Grind Solid (dumb name eh) but these little beauty's are bad ass. Matter of fact, while watching that video, my shop foreman walked in my office and said the exact same thing. I sent a few down to our shop and they love them. They really do remove metal and a remarkable rate...WAY faster than a regular grinding disc, of any type, that I've found. Less vibration and less noise, as advertised, is also true.
Supposedly they will replace grinding wheels (or at least this technology...someday)..not sure about all that, but they are pretty sweet...fyi...

I really like the way you did your tests, I am still looking for a similar, equal-to-all, test set-up. When we find something, we'll try to do the same thing you did, as this is a very important (and time-consuming) application to our weldors.
