    It would be great to see you test some professional brands like what you get at welding stores I feel like they work better than these big box stores brands. Especially 3m cubitron blades for instance

      Hello from one fan from tiny Azores! I love your cientific and unbiased reviewing. One idea, comparing orbital sanding discs, mesh ones versus paper ones. I've been making some research but cannot conclude anything useful, and due to be in a tiny island, only paper ones are available.
      Thank you for your hard work!

        Try cutting a straight line with a simple almost no pressure pull cut and see how you feel about ever using a Lenox for anything that you want to look nice :)
        Regular wheel cuts a groove that's flush on both ends and rides this groove as you pull the grinder down the line. as long as you can keep a relative straight line the disk will do its thing.
        The Lenox is another BEAST entirely. There is no flush groove its a beveled cut where the disk is dancing around as it pleases as you pull down the line it follows no direction from the original groove and makes it own mind which way the line is going to be. It will skip and dance and you will have to reset it back in the groove unless you use a lot more pressure than you would a regular disk.
        The end result will be an oversized hole with beveled edges. A word to describe the end result is BUTCHERED. I will use it on non critical pieces that are going to be used as support or hidden like gussets or L brackets somwhere out of view. I would not cut thick steel with this wheel though. If I had an old grinder i would put this wheel on it permanently and make it a goto grinder for quick thin cuts but if I have to change the wheel on my grinder i may as well put a regular cutoff wheel that can get the job done quicker. That being said if and when you run down you last disk and still have work left to do i think Lenox will be a gem to have as reliable backup wheel to save you a trip to the hardware store to finish a job.

        I agree with Bobby Jones. How about a video comparing the cutoff discs you can get at your local welding shop? I use Norton Blue Fire and would like to see how it compares to the other LWS brands such as 3M, SAIT, and others.

        These were all cheaper big box store brands, need a do over, this time with high end cut off wheels like Sait, Cubitron..... I'm just a weekend welder and I use Sait and Metabo. I was very disappointed in that diamond cut off wheel, I was thinking of buying one but not after watching this video so thanks for that test comparison.

        The Lenox wheel could handle more pressure I believe which would drastically reduce it's time for a cut?

          So many reviews online are biased or have human error in the test, but not you! I used to trust those untrustworthy reviews, bit after I ended up buying trash I watch your review. Sorry for bad English, it's my second language.

          Im sold on lenox since you dont lose diameter. I pinched one and bent it. Took it off smacked with hammer and went back to work with it. No blowing up. Ive also done cuts where i needed full diameter the entire time cutting some thick welds on my trl

          You always make such quality videos and have come up with some great tests for every product you use in your videos! I think it would be an interesting idea to test how effective different brands of flame retardant clothing are for the job as well as how long they would last before becoming ineffective when exposed to high heat, Sparks,open flame,and anything else you can come up with for an ignition source! Thank you for all of the great content!

              I wonder how repeatable this test is? ie. If you tested 10 of each would the results be the same? I think your test rig is about as good as can be expected but I've had some disks wear out much faster than others of the same brand cutting the same material. Of course, maybe the problem is me and not the cut off wheel.

                    I know this is an older video but I have kind of a great video idea for you.

                    Make once a year a video of the top performers in everything you’ve done for the year. That would be a perfect new year’s gift for us subscribers. That way we can all watch and have the shortcut to the best performing brands. Just a thought but I’m placing a large cut off wheel order today.

                    Thanks! I still want tat grease test!! :)

                    It is very very very difficult to judge the qualities of manual cutting discs by one test setup. Every disc is composed of grit, structure reinforcement (fibers) and binding material. With an ideal disc the grit is very wear resistant and the binding material does let loose the grit particles only just after them getting sufficient dull. Letting loose the grit is caused by increased friction forces by the dull grit and increased temperature as a consequence. For clear, these friction forces are not only caused by the dullness of the grit particles, but even more by the specific contact pressure applied on them. And this contact pressure is a function of the contact area and force applied. As a consequence, depending on the section of material to cut on should apply a different force. Most technicians take this reasonable well in account by intuition. But by experience I know that some technicians will consume 3 times more discs for cutting the same lengths as others do. And that's all about feeling. By moving the disc slowly back and forth during the cut, one does continuously play with the contact surface. And for every time they experience some slower cutting progress, they slightly increase the cutting force or move back and forth a little more quick for removing the dull layer. One has to manage this "dance". But, without being conscious, lots of people work too often the "layer removal mode", and they consume more discs. And as every disc is made of different materials, they need a different "optimal dance". And as every technician prefers different "dances", they prefer different discs.


                    In this test, some of the discs could be for the whole test in a "layer removal mode", because of a weaker binding material. And others could be in a soft cutting mode and being quite dull as from half through the part, because of stronger binding material.

                    Seeing as the Lenox is a diamond wheel maybe it needs more downward force to cut as fast as a standard wheel

                        I understand this is a lot of work, and you definitely do this type of unbiased testing better than most, but for a wheel that changes in diameter as it's used, I feel like 3 cuts per wheel and an average cut time would have been more telling. I would be willing to bet that some of the faster wearing wheels would slow down substantially on subsequent cuts . (I know this test happened months ago 😭, still working through the back catalogue)

                          @projectfarm How about testing tire pressure gauges. I've never seen two that matched each other! It's ridiculous. There is no way to test one for accuracy either. When you use one and adjust your tire pressure accordingly, it's just a "feel good" I think. What is it REALLY reading???

                          What I'd like to know is why a wheel seems to be cutting normal and then sometimes, it hits a spot where it just disintegrates? You can see a lot of dust and feel the wheel shrinking fast. I've seen that so many times. I mostly use the Warrior brand & whatever H.F. sold before that one but I'm sure others do it too.
