Did not expect the difference in wear of the discs.
In fact I always asked myself why grinders were turning at 8500rpm when usual electric was 10/11k… more speed more effective the abrasive. Great tool!
Only time I've needed a grinder spanner is when someone else used the spanner to tighten it up before me.
No one at my work use a grinder spanner to tighten or untighten disc. Does people these days not know how to untighten grinder discs by hand?
You are the man tools!
Nice video, and looking forward to more tests you mentioned at the end :)
I am waiting for the version with slide switch and variable speed in any case, like mine 023 has.
Yeah idk what they are doing with those rpms, but this one certainly has more powerful motor.
Great video as always. And while you don’t have the fancy dynos that TTC does, you could always do some project farm type tests to measure more concrete numbers. Maybe the force applied to make them stall? Constant weight while cutting, etc.
Looking forward to the variable,glad they dropped the x-lock as I use carving heads,thanks
The holes in that blade nut is for spanners. My Ryobi grinder has that same blade nut and it came with a spanner wrench to take it off. I’m a DIYer so it’s great for me. Great video my friend!
Love to see this battery on the top Handel chain saw.
I wonder if Makita has speed limited the grinder (to prevent disc explosion), but is advertising its unrestricted speed so that it is comparable to other grinders. You could try a C-magnet and a diamond disc to make a dirtbag eddy current brake. That'll give you a consistent load, then you could compare RPM of diff grinders and batt combos.
Nice review🏆
It is known that faster grinders use less of the disk and if it is not pushed too hard, it uses disks way way less. Dga504 weas my first cordless grinder, worked a lot with it on porcelain, never tried to use it with 150mm disks because of lack of power. But xgt grinders were converted to 150mm with new guards asap. Got quite good balanced grinders. Cant wait to get my hands on new one with these batteries to have fast 125mm grinder.
As a boilermaker with about 17 grinders in my arsenal, any fancy grinder nut goes straight in the bin. Pin spanner is best, if it ain't broke something something
As me ol' dad sez, If it ain't something don't something something!
There’s nothing wrong with nut that has the flip up thing. It has holes of it for a pin spanner and can use a pair of mig pilers to get off also
@@Andrew-xd9fg We had one of them on a company Milfuckee grinder snap the ring then split the casing of the nut, needed a pair of baby Stilsons to free the bastard. Also those metabo ones are garbage too, love their grinders but hate that chunky knurled springloaded doodad that gets filled with crap and becomes stiff as a wedding prick to screw on letalone free up.
I have Makita 18v grinder with X lock , works fine , so far anyway , then again Bosch did manage to make a toolless jigsaw blade change mechanism , and no one want the older system back , the one with screws .
Will test Makitas toolless solution , for DLW140 2x18V cutting "saw" , for 355mmm/14" cutting wheels , it seem to be just a hex key bolt with turning nob , nothing special , thats what the part look like 🙂
Just got my 40v grinder, noticed the power difference straight away its a big step up. Its also a bit heavier and less balanced in the hand I reckon, maybe a 2.5ah will feel a bit better for the positional light work.
lower rpm prolly due to "Soft No Load"- `reduces vibration of tool body when idling, accordingly decreases the amount of vibration to operator’s hands during a day’s operation`
Interesting what you say about the kicking. My Bosch starlock kicks for fun, even cutting uPVC
Part of me wonders if it has something like a soft no-load limiter on it similar to the jigsaw, then when it starts to engage the workpiece the motor ups the speed/rpms and apply even more torque when it needs it.
If that were the case the RPMs will only read ~9500 without a load, but might go up to ~11000 under load.
i personally really like the 5 speed paddle switch grinder how ever im still on lxt and my grinder has enough power for what i need it to do
Hey Mate, again, thanks very much for the informative vid!! Really enjoy your reviews!!! I am in a toss-up: I have a large amount of 18v Makita tools. I recently succumbed to buying 'cheap/no-name' batteries with more Ah than Makita has to offer. (9Ah/12Ah). I found the 18v tools have enough umpf, for the work I do, but certain tools chew through the batteries like hell. Thats why i chose to get a few with larger capacity. I hate(d) having to go swap out batteries, in the middle of a job, i.e Lawnmower, hedge trimmer and having to climb up and down a scaffolding due to this. I'm not saying the 40v plattform is bad, but I wonder, with the more power of the 40v, if the 'stand time' is better, in the long run.... They may be faster, but do they chew through batteries faster, aswell?
They are actually generally better in regard to battery life. Not always, but quite a few tools are more powerful than their 18v counterparts while also getting better battery life with equal watt hour batteries.
Great work. I will see if that chap I was arguing with will now eat his hat
When people deny tool facts, it's often because they're annoyed because they can't afford it, or bought the wrong one and feel the need t to defend their decision. Either that or they're flat earthers.
Haha, what was this about? 18 vs 40v, or F vs non-F battery?
@@toolscientist He was adamant that the last video proved that the F battery was no better than standard
The new 4ah battery is clearly better it out preformed the 5 ah battery from what I was seeing it's also lighter so I will definitely be buying 2 of them
have you compared the milwuakee 5" to their 6" yet? i have both and although i havent used them side by side, i cant really notice a massive difference
all the difference i see in power and cut out frequency comes from the battery on it, go from anything with 18650s to 21700s and theres well over a 50% jump in power, maybe a 5% jump in power going from a 6/8 to a 12.0 but not much
how is that new band saw blade xgt 40v. because my problem was with the blade first. so make another blade?
I'm sure that 40 volt is much better than 18 volt as to be expected but my brushless Makita 18 volt LXT grinder works great! I even started purchasing some Bauer 20 volt tools they're brushless grinder is pretty damn good & is comparable to my Makita haha never had a problem with Makita LXT I run 5.0Ah🔋finally after about 13 years I had to get a 🆕 set of 🔋🔋 & when I started out with them batteries there was not even the brushless grinder LoL... Brushless was just starting to come onto the market.
how does the vibration compare between the 2 given the new model has an anti vibe thing on the body of the tool?
Cool 😎
Finally got the 40v original grinder. Had the 18v for many years. The 40 is slightly heavier, but MAN what a diff. Now Im trying to justify upgrading the XPH14 18v hammer drill to the 40v version. The difference on those doesnt seem to justify it, so I may wait for a new model.
AFT on the XGT drill.
have an xgt drill and used the 18v 481 quite a bit (the xph14 is mainly a shrunken version of the 481) id stick with the 18v they still a monster of a drill. unless the xgt drill brings you one step closer to not needing to carry around two battery platforms
When do we get a 40v die grinder? As a metalworker im loving the XGT platform but cant live without my die grinder
Die grinder and flat head grinder for me
Bosch Biturbo 18v grinder is rated to spin at 11k but its actual no load rpm is 9800k. It states in the app that they may update the rpm when better batteries become available
That seems weird because they already have batteries that have more power output than that tool can accept
1 x 5.0 amp battery BL4050F is around £ 187 UK pounds March 2024. Just like HP printers , the tools are sold cheap as possible to get you hooked on the batteries and the new 40v system tools - but if you really , really need them you have to stay competitive and efficient as possible.
Interestingly the US Makita site seems to claim a 9,000RPM no-load speed for the GAG14 -- at least as of today. Which would make sense since they're also advertising it as a 4.5"/6" grinder and the 6" grinding wheels I'm seeing look to have a 10,000RPM limit.
The earlier versions shown there are either 4.5"/5" or 6 inch grinders rather than a 4.5 inch/6 inch grinder like the GAG14 is being advertised as.....
Makita 40V vs Milwaukee Fuel 18V? I have batteries for both. (old 40v bat)
Had this nut from aeg/milwaukee. Don't like it, got some annoying vibrations with it, sometimes it is very hard to remove. Got myself Makita's quick release nut, it weights half a ton but stable, always releases by hand and no vibration at all. But for quick release my favorite is Metabo quick lock, unfortunately available only on Metabo grinders(where you push spindle lock button while grinder is still rotating)
rpm could be to do with the no load protection makita put on some of their tools, wont run as hard under no load
Would like to see comparison tests with the new Hikoki 36v 6” grinder. Much smaller motor, probably less powerful than the Makita XGT but would be interesting. Hikoki has variable speed and way more power than 18v grinders I’ve used.
On 4-6” grinders the dcg418 reigns king imo and I am a hikoki guy but I just love the multivolt line and I have the hikoki but it’s branded mhpt g3615dvf I believe is the model number but it’s the vari speed 6” and it’s got quite a bit more power than i expected quite honestly and I love the smaller circumference of the grip as it’s different from anything else I’ve seen any other brands put out but the one thing I don’t like is the zero voltage restart or whatever they call it safety feature it’s actually a nuisance…..
I think the hikoki g3615dvf is possibly my favorite grinder out atm unless I’m goin for stupid power then I got dcg418 but the hikoki will surprise and is a good balance of run time power ergonomics features etc…as well as having some grunt for a lighter smaller well smaller ish 150mm or 6”
Any chance they limit the max speed when they aren’t under load? Would seem odd, but if you can measure while cutting it might be interesting anyway.
brushless motors work by having electronics that create a spinning magnetic field. The switching speed is what sets that limit. When under load the permanent magnets in the rotor can't keep up so a bunch of sensors slow down the switching speed, this also ups the current (which ups the torque generated). basically current->torque, and if you had a brushed motor, voltage->no load rpm.
Maybe the new 40v has some stall or overload protection to save the battery and motor. It doesn't make sense to push that hard, maybe it just cuts out to safe you and the tool.
The Makita GA051G 150 mm is 9000 rpm in spec.
Greetings from Russia! It would be interesting to see a comparison between the Makita GA050G and the DeWalt DCG418. According to the characteristics, they have the same output power - 2300w, only the rpm differs, for Makita - 11000rpm (real 9800), for DeWalt - 9000rpm (real 8400). Thanks for your reviews!
Is it worth waiting to get this when it comes with AWS or will it be a few years ?
Dunno
I think the Ridgid octane was rated at 10k rpm which idk how close it got to that but it’d be imo one of the better 18v grinders I’ve seen
It was almost 10k right on the dot. Those things were beasts especially for 18v tools. Makes me wonder why Makita is so much less powerful
@@Dude-xv4osrpm doesn't equal power
If the Bosch 18V-15 series are true to label with 11000rpm and 1500watt equivalent they are more powerful though probably not in real world testing. They do share a lot with Makita, X-Lock, antikickback and the branded cutting discs all look to come from the same factory. They might use the same speed measuring, Bosch state "Speed output no-load, nominal max. = 11000" but "No-load speed = 9,800 rpm" which falls in line with the values you saw on the tacho. The big question though is the high output battery worth the extra $100NZD. Also if the new battery can support a higher current drain can it also handle a higher charge rate than current chargers can put out?
It probably can yeah
so under what circumstances will it ever spin 11,000rpm? whats the point of even having that imaginary figure floating around.. id buy from a manufacturer if theyd make it their mission to just be transparent in everything rather than trying to out bullshi the other guy
what wall plug cord are you using to power the 40v grinder and battery as a corded system?
What wall plug you talking about? It's still a battery(pack)
Yes, more cooperation between you and ttc please.
With regard to the wheel retaining nut, all the fancy nuts are crap and should be discarded as soon as possible. Some anti seize on the male thread of the spindle and don't use a cutting disc down to 50mm in diameter and you will always be able to undo the disc by hand. Boilermaker 64 years old.
You must admire Milwaukee for sticking with the same battery platform this long. Could be time for them to upgrade now, it’s been a long run for the 18v.
they have had the M28 for a while now, but they need something bigger to compete
I like the gen 1 based on the slim design but they are $300
I thought of a better and easier test. Clamp grinder and tacho to a bench. Set up a camera to watch tacho and lock trigger on. Use 2.0ah otherwise you could be waiting a while. 2ah will take ~30min
Now step through vid and write down RPM at 1min intervals in spreadsheet. Plot RPM vs time.
If it's speed limited, you'll see a flat section for 1/4 to 3/4 of the runtime, then it'll start dropping off with the voltage.
i like x lock.
The stall tests were disappointing, I was hoping the new wouldn't stall at all. Probably unrealistic. Is there a case to be made for angle grinders to have a 2 speed switch (if that's even possible) ?
I mean a variable speed would likely solve the torque problem with lower speed option
The grinders have a soft start don't they. Speed increases with load.
I wonder if there is a gear reduction in the 90 degree transition. It might be spinning 11k rpm at the motor but reduced at the grinder spindle.
Ofc there is, like in any grinder. But the motor itself spins way higher than 11k
Generally I found a lighter pressure saves the disc more even if it takes longer....though you need to be a sweet spot where time > disc cost (talking about cutting discs)
As for stalling....I think the newer one could have stall protection safety wise
Yes the wear is on inversely proportional to rpm per material removed.
I prefer the X lock system.
Why not the x-lock?
I'm sure they will make an X Lock version
The newer disc locks are rubbish, I’ve not had one I haven’t broken in a few weeks
Stalling test is not best show of torque curve. The useful torque is what gets put down in the steel without cutting out, so the new one might actually have more torque.
Also, just before the tool stalls it might be spinning 30 % of it's rpm or 80 %.
Close to Festool pricing here in the USA. Right THERE with newest Made in Germany Metabo.
But makitas are better than metabo so no problems
There should be no difference in rpm when testing the flange nut vs the spindle. There always is a difference in rpm when the numbers come from the marketing department instead of the engineering department.
надо было сравнить с батареей BL4025 у неё больше токо отдача
Compared to what? 2.0 and 2.5 are the weakest 40v packs
What makes the 40v better then the 18v MAKITA
I don't answer questions from people who don't watch the videos.
yeah good question. if only he covered this throughout the whole video.
@@ToolsAndStuffOFFICIAL thanks
More power
Kinda like comparing a V8 to a 4 banger
At this point I don't know why Makita don't just become an angle grinder and impact driver company. When I heard that they had released another angle grinder, my eyes rolled.
Milwaukee see to have a power tool for every imaginable thing. I'm starting to wish that I'd rolled Milwaukee at the get go, instead of going Makita 18v then Makita 40v
Makitas bread and butter is industry across the world. It's in their best interest to keep innovating with grinders. I'd for sure love Makita to fill in the gaps in their line though, but it must be making them money for them to keep doing it. Also, the new TD173 impact with the ring light and the battery centered on the handle is a legitimate jump on tech and innovation.
11k rpm. No variable speed. No thank you.
I own an use gen 1 plus the sjs 5" and 7."
Battery good grinder bad.
The problem with the fake spec with tool world is that everyone forced to lie because majority of the buyer is typical dumber who only rely on the spec sheet instead of the real world test 🤷🏻…if you wanna sell more..the spec sheet need to b extravagant LOL…and that is the same reason why many fall for cheap crappy brand tool from chna LOL….common sense is leaving human brains 🥹🥹🥹
