- Опубліковано 13 чер 2024
- Grinding metal is something I have to do every day, and finding the most efficient consumables to do so is a goal of mine. These new grinding discs from Pferd are really something different... ive never used a disc that removed material this quickly before! I tried to make this test as controlled as possible, but theres always room for improvement, let me know what you'd do differently in the comments below!

If anyones looking to purchase these discs, I put a link in the description of the video, and here it is as well. They cost about $6 per disc in a pack of ten for $60US. bit.ly/4blOPup
3m cubitron and tiger paws are the industry standard in oil and gas. As a welder there is no better when your time and production matters. It is that simple.
Cubitron is great
Some of those disks started strong but then stopped once they wore out. Maybe instead of testing for grinding a specific distance, go for a fixed time and measure how far they cut. Run them each for one minute and then measure how much was removed.
Was thinking something similar. I'm not a metal worker, but would you ever grind that much material? Wouldn't you cut off the bulk and grind a small amount?
Those discs look amazing though!
@@NickMomrik Generally yeah. But sometimes things are in bad positions so you can't get a good angle for cutting, but can for grinding. For example: imagine a 90 degree interior corner, with an interior fillet with a 1" radius. A cutting wheel would not work very well because there's no way to get it flush to either side of that 90deg structure. The only way to go about it is to angle the grinder, and hit it with a grinding disk
What do you consider when you choose those disks?
@@NickMomrik as already said sometimes you can't get in to make a cut first, but if you are doing a lot of grinding using the edge of the wheel would grind faster and last longer.
@@cameronbateau6510 It's how fast they cut vs how long they last. Depends on use case. Do I want a slow cutting disk that lasts forever, or do I want something that rips metal but doesn't last long? Are you concerned about time and labor rate or the cost of materials.
Wow, that is amazing. Love the Pferd abrasives and they DO last a LOT longer than the ones from the Big Box Stores. Thanks for the demostration/test, Chris.
Chris, I have no doubt your test was unbiased and completely fair. Truly love and use Pferd discs. As a one man operation myself, I know people will say in the long run you save 💰by using this product, but for me sometimes I cannot justify the cost, they are pricey. Other brands and “knock off” brands some of which I can purchase 10 to 1 against the price of Pferd. That works for me. Not knocking Pferd, but sometimes I don’t want to pay that much. Loved the review and comparison.👍👍
Totally get it, I think they are reasonably priced in comparison to other set of discs just to try out, at about $6 per disc, they'll go far!
@@MakeEverything Thank you CHRIS! Will do!👍👍
I’ve never tried Pferd discs but just ordered a few packs since your test seemed pretty valid.
I’m impressed it’s a great disc and a fair test thanks for sharing
Love your videos very informative I love to learn more each day thank you for your knowledge
I’m a believer of the original CC Grind disc, now I’m going to order some of the Robust ones. Thanks for the heads up!
Great content and learning
I've never heard of this brand before. I will definitely give them a try. I learned the hard way that a good disc makes all the difference in the world. But I learned it on my chop saw . I got desperate on a weekend and ended up using some Harbor Freight chop saw blades. You would have thought I had soaked them in oil. Talk about useless. It makes absolute sense to me that a good grinding disc can make a world of difference.
Really appreciate you 😊‼️ Because of your video I started using the pherd victograin about a year ago and nothing comes close to! Trying to figure out what to do with the hard rocks I have around my shop 😢 Can’t wait together my hands on the Robust - Thanks‼️
I couldn't believe how much better these discs are than even those other discs... Really wild what abrasive technology has done!
You should have project farm I think it is test them
Thank's again for a great demo. Pferd discs clearly perform great. I'm definitely curious and will get my hand on one of those to try it out.
I wonder how long do they last. As a hobbyist, 60$ worth of stone and flaps last me a year.
How many amps is your grinder? Thanks for taking the time to do the comparison. It's alot of work and time to put a vid together like this. Just ordered a box gonna try em out.
I would want to figure it why it took 5+ times as long in the second piece with the same disc. Might be something to the weight vs deglazing the disc? And then - looking at the other discs, they seemed to slow down more over the course of the test. There might be a recommended pressure to put on them while grinding to prevent glazing? Then you could do a longevity test - once you get the pressure right to prevent glazing, how long does each disc last?
I would be more interested in the differential of the cost of the time vs the cost of the $ to buy the discs.
That analysis led me to stop using hard grinding discs altogether, once i found a good flap disc. Guess i just hadn't found a good grinding disc yet. I'll be trying these, thanks for sharing 😊
🔥🔥🔥Great video
The corseness of the disc plays a big role in material removal
Hell yeah that’s a bad ass disk!!!
That's CRAZY fast!
Gees thats quick. If the price isnt crazy I'll giver a go
Love Pferd, they are top quality. I’m just gonna call BS on the 60 grit flap disk. I’m not saying it would beat the first disk but no one uses a 60 grit to remove a bunch of material unless they run out of their 37 and 40 grits. I was looking forward to that one. Boo
Still love ya love your show! Keep it up!
Have you been watching Project Farm? After watching this, I've got these on my list. Thanks!
Pferd also do a Combi Click disc system for grinders that's worth a look, especially for fine finishing.
Very interesting results!! I like the simple but effective testing setup! Someone below suggests a "how much" per a fix period of time.. I'm thinking $... what's the cost per unit of grinding.. maybe $/mil ground away? Please going with this type of content! thanks again!
Good point. A commercial shop paying wages might find the saved time in labour out weighs any additional cost but a home shop sort of has free labour so saving money on tools can be more important.
My only complaint about the test would be that you didn’t use the lead edge of the wheels like in a real world scenario. Aside from that Pherd is a reputable brand, others have comparable if not better in certain products. I like the metabo contoured flap disc on their flat grinder better than any other. The cups on a 7” grinder are great for cleaning a layout table followed by a 7” flap if it saw heavy used.
Have Torque Test Channel test these
Very fair and has shown to be very controlled test.
How much for your used CC-Grind discs? They're better than my new discs.
Is there a great Pferd cut off wheel? I use that type of wheel more than any other.
Do you ever use the walter discs? also hard to find and about the same price I think.
Wonder how they compare to the newly released Cubitron III by 3M
Cubitron II already is awesome .... Cubitron 3 is waaay better (like 2x better)
you can already get Cubitron 3 they like WOW literally WOW
eats metal like if it was tungsten carbide end mill in a cnc --- flying chips not sparks (literally)
you can feel it bite the metal like if it was made from plastic
i was using fibre discs earlier 982c and 982CX --- the X version is epic - seconds to grind 20mm screw to 0 , you can find awesome disc shapes , types etc if you check what they offer
--- its designed to withstand few x more force aplied to the disc , and it needs more force to grind fast , yet its specially designed to work with it and will last 10x longer than any "standard" disc with "standard" amount of force aplied (or belt for belt sander) and won't get shredded if you push something sharp into it (hard screw etc)
Cool review and appears to be a product I would like to try since I weld. I went straight to amazon and nope, they’re not available. Ok, no problem, I go to eBay and there is 1 disc of this description available for $93.28 in Italy and add $17.99 to ship it to me in Texas. Plenty of the cc grind solid variety on both sites but not the item you reviewed. So where do the magic grinding discs come from? And how much should I be prepared to pay to get a box of them once they arrive in America? Stupid Pferd website wants my tax ID number to even allow me to sign up as a customer.
Hi Ronald, Check the description because I put a link to them at Fasttool for $60 for a pack of ten! Ill pin a comment here too
Tried to order from Fastool using PayPal and unable to place order. Called Fastool and got answering machine. Now have about 30 minutes invested in failing to obtain any of these magic discs. Sorry man, it’s a no go. 😢
Again thanks..
Great demo, read all the comments that were good suggestions and comments. It appears the number on issue is cost per discs. One man shops or hobbyist will have a tuff time justifying the cost. Second is the availability, lets face it, when you need a disc you can't by standing by the mailbox waiting for it to show up. Maybe when they get their cost down and availability issues trimmed down, more people will be willing to go some of the extra cost.
Thanks for sharing.
I think the cost is reasonable but I totally get it. People take a while to realize that “expensive” consumables make up their cost in time saved! $6 a disc seems reasonable compared to what a normal
Consumer pays at Home Depot for a flap disc ($10 each)
Pferd are brilliant
it helps to grind where the disc is moving fastest - at the outermost point of the disc. The dewalt appears to be grind near the arbor. No doubt slower than your sponsor - but disadvantaged too. you reifornce my thoughts ar 12:44 when you are grinding off-center. everything after your first run was sub-optimal.
What's the best 9" disc?
Maybe the same could be said about why a katana cuts better than most is because of the curved edge. Very little edge (surface) means very little resistance. Some might have a better design but low quality which would yield good results. But with great design and equal quality is a game changer. Just a thought. Either way. Seems like a great product.
I am a hobbiest, weekend blacksmith. Does it make sense to spend the premium money for me? I can see it for the pros, for sure.
I think so... For $60, $6/per disc its cheaper than Home Depot flap wheels that most weekenders use...
Yknow, $6 a disc, if it holds up, isnt expensive at all. Im interested to see who says what can do better.
My thoughts exactly!
👍👍
👍🏻👍🏻👍🏻👍🏻👍🏻
I think a better way of doing this experiment would be controlling for grinder power (with a power meter on the mains plug/cable) instead of controlling for weight, i.e. compare new abrasive vs "stone" disc at a load of 1hp / 750W or whatever, rather than both at 5lb of weight. Your experiment shows the new abrasive can hog off more material with less pressure on it, which is great, but my feeling is the old abrasive could also remove material that fast if you put (probably quite a bit) more pressure on it. I don't use grinders all day so the fatigue aspect isn't really an issue, but do often find myself hitting the power limit of the grinder (esp. with a cordless one tripping out).
I wonder how that intersects the glazing issue? How hard do you have to lean on it to prevent glazing, so the whole disc costs as fast, and which discs are even compatible with a cordless grinder, due to the force required to prevent glazing vs the load the cordless grinder would take? I'd do that test with a brand new 'cheapest' red or yellow 4 1/2" angle grinder with the battery that comes with it in the kit. Then you'd have a list of discs that are even compatible with a cordless grinder..
Are your subscribers mean? 479 likes out of almost 8k views. WTD is their problem. I admit I have watched very little of your videos. Someone stole most of my tools and it's hard to watch other people do stuff just yet. Lost about $15,000 in 2 hits. But this was a great comparison video. I just don't understand people anymore. Thanks for the video. I will save it for when I get another welder and grinder but for now I don't even own a vice or anvil. They got 4 vices and 2 anvils. Gonna be a while. lol
Those grinding wheels might be good but people won't pick my job estimates. They are very expensive. Good for me but not those paying for them. At $ 66 per wheel I will be without a job.
$6 per wheel, $60 for 10…
(Norton SG Blaze 5 inch diameter fiber back ceramic 36 grit) I'm not saying it's better than yours but I think it is faster
My 80A plasma "disc" would cut through that in a couple of seconds. 😃
I see your plasma and raise you an arc gouge!
Cubitron 3 be like
NOW ME (except the price 😆 Cubitron II is great - fibre disc 982CX go in metal like in butter and last rly long time)
yet overall both solutions are great because even if you think its expensive ....in reality when you start to use it its waaaay cheaper because maybe you pay like 5x more per piece at start ... but it will last 10x or even longer while working few times faster than cheaper solutions
all parameters should stay the same and then you measure the distance. Don't add weights. Don't change the angle. All disks new out of the package.
They were all brand new out of the box... some discs needs more pressure than others
They look awesome but apparently they are unobtanium....
Putting in a pin comment now on the website that sells them for about $6 each
@@MakeEverything thank you!
Impressive disk.
Unimpressive availability.
