They are using spring loaded push in connections because they tolerate much more vibrations and are self-tightening. A screwed connection could loosen over time. This is pretty standard here in Germany when it comes to electrics.
Greets from Germany!
I had thought a screwed connection might be more susceptible to loosening from vibration and that might be why.
to add, soldered wire on screw terminals are not legal for grid operation.
I honestly don't know why they did solder instead of using Ferrels
Anxious Merchant because they use spring loaded terminals and therefore solder is legal and easier to apply.
you prolly dont care at all but does anybody know of a tool to get back into an instagram account?
I was stupid lost the account password. I love any tips you can give me.
@Hunter Ronald instablaster ;)
do more videos like these please, comparison of brand teardowns, this was 5/5 fun to watch
I have a 13amp metabo grinder and two cordless metabo. Absolutely my favorite tool right below my tig welder
I have the paddle switch version of this angle grinder (wp8-115) and it has held up very well for over five years. Two of which I was in a trade school so it was used every single day. I was always worried going in that the clutch would wear out over time and it would lose its ability to cut, but so far that hasn’t been the case at all. The trade school I went to is actually what turned me on to the grinders. The instructor said that when they first opened up multiple companies approached them wanting to give them sample products, grinders, welders, welding hoods, grinding discs, so on. I cannot remember off hand all the brands of angle grinders, but I know the instructor brought one of his personal metabos that had been already used and abused for years, tested it for a few months against the others that were supplied, and the metabo still outlasted the others. I now own two and will not go back to cheap angle grinders. If you do even the slightest amount of welding or metal work you really should invest in good tools, and one of the most used tools in a metal shop is the angle grinder.
I have a 10 year old Metabo w14-125 that I have replaced the brushes on 3 times and it has outlasted more DeWalts than I can remember although the bearings are starting to get noisy now.
Just wanted to let you know you still have support out here for your videos. I really like the teardown videos man. You do a great job. Thank you.
Very interesting & enlightening - I've just ordered a Metabo grinder because of your excellent, detailed review.
The build quality, superior engineering and the S-Clutch swung it for me.
Many thanks......all the way from London !
Nice video, I rebuild gear boxes and plastic shims are very common, Just like the clear plastic ones. They do flake apart on gearboxes I disassemble that have been in service since the 1970s. But, they were holding the tolerance the whole time, And I’ve never seen them be the cause of failure. Pretty impressive.
I love the metabo grinders. When you're using it in a heavy environement thats when you really get to see the difference. The quick change nut design and having the clutch is the best part of the metabo. The clutch just saves your grinding and cutting wheels from exploding when it gets wedged. The quick change nut makes it so easy that I've been spoiled.
When i use my milwaukee or bosh they are strictly for just grinding or using a wire wheel because i hate having to use a tool to take them on and off because its so hard. Milwakee had an update on the gearing and went to the straight gears like the metabo instead of having the ring gear type and it feels a lot smoother. If i had to choose it would be the metabo hands down. Metabo just saves you from being jerked around all day. Great video!
Knowing now that most tools are made in China, it's kinda a toss up of which to choose. I've been buying several metabo tools lately because of build quality and better part choices. Like chord type and length,etc.
Your vids are very beneficial. Keep up the good work.
Love to see a tear down on a Tacklife and a Hitachi/Metabo grinder
The brush length might be the same but the width is significantly different. A narrow brush will wear faster because of the smaller contact area. It will also have higher electrical resistance leading to higher temperature. You did mention harder material but the pressure from the spring will be important because it will affect wear on BOTH the commutator and the brush. Brushes are replaceable, commutator not so easy. BTW, you’re getting “coil” springs and “flat spiral” spring confused. Coil springs more commonly refer to a constant diameter such as the springs in your car’s suspension.
The plastic plate isn't an an issue on Metabos. I maintained many of them and my personal 6" Metabo is ten years old and finally managed to wear the gear teeth enough to require replacement. Under thirty bucks and the rest of the grinder (including brushes!) needed nothing.
I don't know much about tools, but I like to tear them apart or watch it. Thanks for your work and explaining the stuff, what goes on inside the tool. Keep it on! =)
I really like these videos. They are well made and narrated and concise but detailed. I would like to see a teardown of the Porter Cable 4 1/2 inch grinder.

Spirl cut is stronger in most cases in one direction, truck axles will be reversed front from back as loads change heavy use. Straight shear easier however spiral needs a good contact with pinion. I do appreciate you taking time and money to do this. The clutch setup is now appearing on higher end grinders. As is soft start, oddly half the tool guys go oh it seems weak but its safety to not jerk and less fatigue for user. I also like the breaks on grinders and on circular saws. In my area dewalt has been the go to and last. Now makita rat tails were the go to for a long while. Both of my dewalts are made in u.s.a. one was gift and one the wife bought me. I'll say my newest 13 amp is very nice but I highly recommend buying good disk and cutoff wheels. Cheap can come apart and good ones make ok tool work like super star but cheap ones make it a chore.
I'm subscribed, I've shared and I even went out and bought a bag of Doritos that were advertised at 16:55. Great channel. I like the direct tool talk without a lot of BS.
Thanks for watching a subscribing.
Very well done ,not that much surprised me in your findings although I may had been slightly surprised at the Hercules over all quality and build I’m a retired Woodworker and a fan of older Made InUSA tools as well as German made power tools mostly Bosch
Please make a teardown of the harbor freight machining tools ( mill,lathe).
"Take that picture of your family off the wall and replace it with this" That's hillarious!
I spewed my sauerkraut juice all over my monitor when I saw that!
German made products seem to always being good products
Awesome awesome awesome tear down!!!!
I have a metabo, has been taking a commercial beating for years! Power wise the metabo is superior
Thank you. Truly impressive.
That hercules seems pretty well made, i've been using one of the $10 ones for over 5 years while working on my own or my friends cars, that hercules would last me a good while.
Would love to see if all the hype on Fein grinders is legit.
related to Fein. I have few of those. The smaller ones 115mm disks are made in China. I was surprised to see that since in their advertising proudly present the brand as the only that does everything in house and have an engineer that takes a tool from bearings and assembles everything 'till the end product. If Fein cut costs ... than it's bad ...
Thank you Sir
odd the metabo had a powdered gear where the others had hobbed steel gears.. i wonder if its a case of metabo cutting corners or if the powdered sintered gears can be made to last as long or longer than machined steel ones
Epoxy and Kevlar wraps are the best way to keep the copper winds in place, although I highly doubt the Harbor freight one had kevelar wraps on the armature.
The advantage of a metalic bearing mount is it wicks heat away from the bearing generated by the seals.
Would love to see a teardown of the equivalent Hilti grinder!
Perfect review and summary.
That handle that came with the Metabo is from a SKIL brand angle grinder.
Subscribed and liked! Nice job. BTW - any thoughts on different price-point Metabo grinders? Kind of curious what makes a $49 Metabo vs $249 Metabo of the same size?
German made vs Chinese
they use plug in connection cuz its easier and faster during the manufacturing. i think metabo its still made in germany. and here are labour very high. if they wanna compete with the chinesium grinder. i took a few older and newer metabo 230 volt grinder appart. i think the older grinder are nicer then the new ones. i would not recommend to cheap out on grinder even if you use the grinder only for 2 minutes in a year. its much nicer and safer to use a good quality tool. u can cheap out on outer things but not on tools.
Bear in mind that this metabo is rather on the low-end side of portfolio.. they have much more ruggerd tools too.
We want same type on impact drill. Please 🙏
newer hf power tools seem pretty legit, definitely not as good as those big name brand, at least it is certainly up to my standard as a DIYer, and pretty good value.
Hercules brand does real work man. All their stuff is awesome.
I'll take option e: get the orange harbor freight central pneumatic $20 grinder, has good reviews on harbors site
I’ve had an orange HF grinder for about 15 years and put it through hell and it is still working fine. Not bad for what I paid for it. Definitely a cost effective tool. Plenty of power too.
IV got a metabo angle. I always presumed it was the quick change adapter slipping when I'm over cooking it.
No it's to keep the wheel from shattering and flying at your face.
Made in germany angle grinder the best
Should do a die grinder tear down comparison next.
Great review, great channel. Many thanks!
Thanks for the kind words.
I suggest you test angle grinders cutting much thicker scrap, at least 1/2" plate or 1" rod or bar. They'll handle it if you let the cutting disc float on the workpiece and that will be more informative than cutting light stock which any grinder can manage.
As we found in this video, not every grinder can handle the cutting test: ruclips.net/video/Gu4Y_R29ZMo/видео.html
I have the chip one for 3 years now still going strong. And ya IM a DIY dad not in professional use.
I think it's interesting how sintered metal gears are frowned upon in tool reviews but nearly all top quality stainless knife blades are sintered and more expensive than forged blade steels. Of course Tool Teardowns hints on the primary reasoning in this video in that sintered blade steels can include components to improve the blade characteristics that you simply cant get in forged steel. Just an observation, I guess...
The difference between sintered powder metal gears and powder metallurgy in knife steels is that the knife steels undergo an additional forging process after the powder is produced. Increasing expense, and producing a very fine grain, but extremely strong steel. Sintered powder gears don’t undergo additional forging, they are simply stamped powder in a die, and then baked to set.

Glad you don't cuss like AvE does. You seem to know what you're talking about, you're to the point, and you're also funnier.
Definitely earned my sub.
subbed. Excellent - thanks
Nice content ...thanks!
Would any of those armature from all those cheap grinder go in place of the metabo ??
Metabo sounds stupid is why.
Great video and keep it up
.....Metabo greace is probably fluid greace for gears, grade 00. ....
I'd just like to comment that this is an out of date base model Metabo.
Their new grinders have no competitor that even comes close. Unlike other obsolete brands....cough* Snap-On cough*
I was looking for my first grinder. Never needed one til recently. I was specifically looking at the Metabo and a Dewalt.
Skipping on Milwaukee, even though I really have had great experiences with their products and like them. Skipping on Makita and Bosch based on another tear down I saw of one that was roughly only a year old video.
Still considering Dewalt, I've had good experience with my wet dry vac and hand sander.
Most likely going Metabo though.
keep up the good work!
nice german fräulein:-)
Good video, buddy!
Enjoy your videos. So I am looking at two grinders.A Tilswall @$31. a Tacklife @$52. Both have epoxy on the stator,sealed bearings as far I can tell from the pictures/wording on Amazon. Both come with 6 disks, the Tacklife has a case and anti-vibration handle that the Tilswall does not. However the Tacklife is 8.5 amp and the Tilswall is 7 amp. and 12k rpms for both. Is it worth the $21 more to get 1.5 amps ? Would I notice the extra juice of the 1.5 amps? I look forward to your comment? Thank you in advance.
DeWalt user here
The handle looks like it came from a ryobi considering it has a wrench in it.
It’s a no brainer the metabo will outlast either of the other two brands of course it is higher priced . But if You grind all day everyday the metabo is what you want. They take the abuse that’s why most pipe fitters use them.
16:50 you're using the adjustable spanner the wrong way
Great and informative video but. I'm a pipefitter and have seen many people damage these by using the button to stop the disc while it is moving. That it horrible advice and voids the warranty on your grinder should this cause damage. I use gloves and after locking the wheel, I hit the edge of the wheel with my hands in the loosening direction.
You're correct if you're using a normal grinder. However, the directions for the quick-release nut on the Metabo specifically say to stop the disk with the button. You're not voiding your warranty in this case because that's how it's designed to work. Check out Metabo's own video on it here: ruclips.net/video/fs2nmUtfFuY/видео.html.
But you shouldn't stop the disk with the (lock) button when it's spooling down.
Metabo The best 👍👍👍
Dude you skipped a lot of info on the Dewalt and Hercules gearboxes
Get a used metabo for 30,- I’ve gotten 4 and love them...
@Jason H Amazon that's were I got mine
Not as entertaining ax Ave, but interesting.
The Metabo is made to make up for rookie moronics; trust I had to be beaten over the head to stop burning out the bushings by forcing the grinder instead of just allowing the tool to do the work.
Don't be a tool; use them instead.. 😎
Another huge difference in these three is Metabo is the innovator behind many of the features and even pattens which Dewalt and Hercules were only able to emulate after Metabo.
In the pipeline welding industry of the oil fields if you don't use Metabo you are wasting money.
The real difference is use an 8" side grinder on 48" high pressure pipe for 12 hrs/day, and you aren't worn to death be the failed ergonomics and torque, etc.
Bosch is a horrible, horrible company. Horrible. Hands down wind the award for least reliable and most failing tools ever
There, on the other hand. Metabo has stepped away from their more "German" ways in an effort to reduce overhead. I will say their adaptations are better than avg still.
Are you absolutely sure Metabo's are made in Germany? In 2004, Metabo restructured the production and a plant in Shanghai china was established. Yeah. Another good company racing to the bottom.
This Metabo was made in Germany.
in right circumstances the cheap HF brand work well, but agree they are junk. a friend has 2 of the HF grinders in a body shop, 1 I opened new 2 years ago, 1 is used only with cutting wheels, the other grinding wheels, I personally have put in 50 + vehicles of cab corners, rear quarters, fender wells, & patches, 2 clip jobs, majority done with them 2 grinders, on the clip I did use a HF reciprocating saw to do rough cuts & to cut clip off donors. the trick is to not load heavy, we only cut sheet metal, or the braces, of several layers of sheet metal, if grinder gets warm sit it down for 30 min & let it cool off, & work on something else. & for grinding all the spot welds, we use the HF grinder to cut close & then a cheap HF air grinder with a 3" 36 grit twist lock to smooth welds.
at home I have a good selection of grinders, vintage Milwaukee 7" B&D 7" Makita 7" newer Dewalt 7" as well as good & cheap 4 1/2" grinders, but at shop when working I use his tools
Well at least you get a brake fr grinding
Harbor Freight is junk. Only get consumables from them. Had three grinders that didn't even make it through one cut before they died on me and I had to send them back.
They stopped using SJW cords because they were problematic
I see what you did there
You sound almost exactly like John Mulaney. I watch all these videos pretending they're in service to an eventual punch line.
