Bosch GWS 18V-125 SC BRUSHLESS GRINDER - 6.3Ah CORE Battery

[@shifty277]

Hi guys, just wanted to say great editing and in-depth looks on this. Side by side video for the viewer of the battery powered units on both legacy and the the new battery technology compared to the equivalent powered mains tool is fantastic. Really really grateful for the content and time you guys put in as i'm not able to just pick up 100 different tools and test them out each year before pulling the notes out of the wallet to make the real world best purchase choices. So thank you to you guys for putting the time and effort in for us viewers, I whitelist your channel from my KZbin adblocker on desktop and watch ads on my phone to make sure you guys (touch wood) get the rewards back for the effort you put in. I'm watching from the other side of the planet! Watching from London, thumbs up on this vid & GOODAY MATE!

[@OZToolTalk]

[Dwain] wow thanks for the support Ryan! It's nice when people really 'get it', that we are trying to help people make good decisions, and also to like tools as much as us ;) You're a champ.

[@overexposurevideo]

nice one! now I need the EC version so much more power, thnx again

[@ellasOLE22]

Unit is a beast, so happy to see Bosch releasing some great new 18V tools. Now they have the best recipro, best grinder, best multitool. All they got to do now is release a new Impact driver

[@StewFairweather]

To be honest, Bosch's GDX 18V-EC (not sure what it's called in US/OZ) brushless impact, although it's 3/4 years old is still a beast. Especially if you pair it with the Core/Eneracer batteries. Those batteries give all the tools a bit of a boost. Highly recommend them.

[@teeg3275]

You've obviously never used flexvolt

[@terryinozland]

And upgrade their baby blower to something really impressive to boost my "Ego". To be the best out there would be awesome.

[@uglyashelful]

Agree

[@ReticentArc]

Technically its the second brush less grinder Bosch have made, their little 10.8v unit is also brush less. Never the less this is a great step for them in particular the eneracer battery and the Bluetooth connectivity.

[@OZToolTalk]

[Dwain] nice pick up, I forgot about that one, not that it's a REAL grinder ;)

[@ellasOLE22]

Also thing to note: where they say its 1000W doesn't mean they have compared it to a 1000W grinder. What they are refering to is much more likely the fact that with the Core batteries, it can output ~55Amp to the motor. This therefore gets you the 1000W of power. Using the tool though will see temperature spike and maybe the amps drop to accommodate for that, and thats why you see the performance not the same to 1000W corded. Because a corded tool is always going to run at MAX input power. Thats why its super easy to burn out a corded motor if you don't know how to use tools.

[@OZToolTalk]

[Dwain] I see your point, but the actual Bosch marketing claims, "Delivers power equal to 1000 W corded "

[@Hidegety1]

I dont think it was thermal protection but rather anti kick feature - which sensed that the disk got stuck and shut off to prevent the kickback.

[@Wroom90]

I have now tried my ginder for some hours. The power is better than the old version, and size significantly bigger, but fits well in your hand! It is very easy to switch the protecting shield position around, and can easily be taken off. The power of the motor is fairly good with a 5 or 6 ah battery - maybe it's better with the eneracer battery? Comparing it with Makita' new brushless grinder you can feel that the Bosch model is much stronger! The tool also have some interesting bluetooth features, which I think are not as useful as being cool. I don't like about the tool that if you slip the power button you need to stop the machine again completely before restarting it. If I would buy the grinder again I would stick with the model without the bluetooth stuff.

[@OZToolTalk]

Joachim Osmundsen I found the buttton issue annoying myself ! I used it a few times after borrowing it off Dwain and was often frustrated. Small thing but annoying nonetheless. (Mike)

[@OZToolTalk]

[Dwain] yes much more power with the Eneracer / Pro CORE battery.

[@jed6rar]

they have a paddle version now if you prefer

[@sw86241996]

Core battery- I have being waiting for so long time finally released, love new grinder which is really big step on, in past 3 years my old 125 grinder still keeping going and does job. Probably just wait for Bosch sell pro core Battery separately on the market.

[@OZToolTalk]

[Dwain] yeah the newer batteries are going to change the cordless market..

[@jwiz8586]

wei shu the bosch core 6.3 batteries have been out in the USA market for 3 months and make every bosch tool I have at least slightly more powerful. However the new brushless grinder is not out in the USA. A putty because I use a cordless grinder beyond capacity more than any other cordless tool I use. The brushed bosch cordless grinder I have has held up well for almost 2 years now, but I could certainly get jobs done quicker with more power.

[@OZToolTalk]

you won't be dissapointed J Wiz.

[@terrygoyan]

It is always tough when a new tool comes out that is so much better then the tool I have. Time for a new battery system? To much invested in makita and Milwaukee batteries! Nice review as alway Dwain!

[@ellasOLE22]

Go blue! Really reliable tools aswell. In the hardware shop that i work at, we barely get any Bosch stuff back for repairs, cant say the same about Makita TBH

[@OZToolTalk]

[Dwain] imagine how broke we'd all be if we swapped platforms every time another brand releases the latest and greatest version! lol

[@terrygoyan]

Ha ha! That explains why I'm broke all the time! Toolaholic.......

[@fabiokkaturagui5845]

Ainda comprarei esse ano. Excelente ferramenta bosch

[@peacockealot]

I think you’ve got the designations the wrong way around. From looking at the grinders on Bosch’s website that you’ve linked in the description the C model is the one without the connectivity and the SC is the one with the connectivity. They don’t mention an S model.

[@OZToolTalk]

[Dwain] yep the SC model is what I was talking about (the one with an 'S'0. Without having rewatched the video, perhaps I didn't get it out well.

[@sergey4162]

The question is, putting aside bells and whistles (Bluetooth), is it underpowered compared to previous brushed model? Maybe it is still better to get older 18 V-LI model in solo and equip it with recent 6.3 or 7 ah batteries? Brush maintenance seems not a problem to me

[@OZToolTalk]

[Dwain] It is much more powerful than the brushed model, which I used to own :)

[@cantor0305]

@@OZToolTalk thanks for that response. after reading it i cancel just in time an order on amazon for the older brushed on amazon an i order a brushless one. the brushed one was even more expensive ! i first chose the old model because he is shorter.

[@advparikshitbade3364]

Is it available in India?

[@sprescav]

my grandpa surely would be exited about the bluetooth feature

[@justawordaway]

Depends on whether it has a canine,incisor or a molar onboard and which one he has got missing.

[@jasondreckmann3396]

Try and get your hands on a dewalt dcg413 to test out, i haven't tried to bog mine down but it feels like it has plenty of power, pretty happy with it.

[@OZToolTalk]

[Dwain] We definitely will be, but it's not quite out in Aus yet.

[@jasondreckmann3396]

Oz Tool Talk alright, wasn't sure if it would be. Its available here in the states but with a wait time through all the retailer's, luckily my brother works for a service center and ordered mine directly.

[@dazaspc]

Good looking little grinder. It looks like it has brush covers on the sides? That app looks a bit better with its ability to data log, can it disable the tool? Is it a 9000 or a 11000 rpm machine? Another great review Cheers

[@ellasOLE22]

9000rpm. Looks like all Brushless grinders are in that RPM range, only the brushed units RPM really high. Wonder why :/

[@dazaspc]

I know corded grinders that are made for stainless are 7500 ~ 9000 rpm (Bosch has this model for example goo.gl/eHzJY8 ) . But I severely doubt that this one could handle extended stainless or masonry work. One day someone will make a grinder disc specifically one with a weaker bond for these low torque units that will stay sharp with the lower loads used. I know you can use a flap disc but sometimes that isn't up to the task.

[@ellasOLE22]

Flexovit make a disk specifically for cordless tools. Look it up its called the "Flexovit ion" Says its meant to increase the battery life of cordless grinders too.

[@dazaspc]

Its a cut off wheel though not a grinder. :( Correction just had a look at the catalog and noticed the grinding wheels of the type, will head of to blackwoods and grab a few

[@OZToolTalk]

[Dwain] What benefit would a 'cordless' grinder wheel have? I don't really understand. And as demonstrated, this unit isn't really lower torque than a basic electric anyway...

[@amana1480]

2:29 Why would a higher capacity 6.3Ah battery make the tool cut faster? A higher capacity battery should only make the tool cut for a longer amount of time?

[@OZToolTalk]

DIfferent cells have not only different Ah (total storage) but also different output caacity (Amps). Often higher Ah batteries have LOWER power output. But these ProCORE batteries have different types of cells (20700 compared to older 18650), which give it a higher output capacity.

[@okafka5446]

@@OZToolTalk I think the batteries here are Core batteries, the ProCore batteries use 21700 cells.

[@dkconstruction50]

Hi grinder price

[@advparikshitbade3364]

Is it available in India~

[@MADEFERmultTEC]

Waiting for it in Brazil for September 2019

NICE TOOL BRO

[@chacebaso235]

Does anyone know when the new Bosch core battery will be available to buy from stores in Australia

[@OZToolTalk]

Chace Baso I don’t think there is a release date yet. .. STILL.😬 (Mike)

[@asfanizam3269]

please do review for wall chaser like bosch gnf 35 or what ever brand they have

[@OZToolTalk]

[Dwain] hmmm, maybe one day.

[@asfanizam3269]

i hope so you can review this product

Bosch gws18 v 45 How to rotate guard

[@Skidbarrow]

where can you get the core batteries from in aust? Thanks

[@OZToolTalk]

[Dwain] I've only seen them in kits so far. Seen them in TT and Bunnings I think.

[@ashtonlowe6761]

How does it compare to the flexvolt power wise

[@OZToolTalk]

[Dwain] It's not in the same category as the flexvolt. Nothing is at the moment. This is still under 1000W equivalent. The FV is more like 1400-1500W eq.

[@juniorsacwed1524]

helow, approximately how many hour continuously run time for this tool. coz i like to buy one. thankyou

[@4everzapy]

hours??? hahaha 10 minutes in economic mode ON

[@Wroom90]

I have it, and love it!

[@OZToolTalk]

[Dwain] how long have you had it for? what do you use it for?

[@Wroom90]

I've had it for two weeks. Haven't actually used it yet. It's hiding in my closet :) I'm intending to use it for all applications

[@Hunter-kh7li]

This one is made in Germany? Their brushed grinder is made in germany

[@OZToolTalk]

[Dwain] pretty sure it is. will check next time im in the shed.

A shame that the continuous runtime is about 10 minutes....

[@yyeyeyhwyege3281]

Price in saudi arabia

[@kendigjl]

Bluetooth for a grinder? Why make the thing needlessly more complex, so that 10 years from now you have a tool that is more likely to have problems?

[@OZToolTalk]

[Dwain] So i guess just stick with a basic brushed unit then? Or better yet, an electric unit. Much less chance of issues ;)

[@MyFatty69]

whats so good about the core batterys ? they are both 18v and 4/8amp. whats the discharge rate on the core batterys compared to normal cool packs ?

[@OZToolTalk]

discharge rate is significantly higher, don't know the numbers off hand. The larger cells inside enable it.

[@amana1480]

Why would you want to connect an angle grinder via Bluetooth to your phone loooool

[@ironpirate8]

Agreed, I can see absolutely no point in any of those features controlled by the app

[@MrJtown420]

It's so you don't lose a tool at the job site. Or if one happens to walk off. Considering how many tools have disappeared I was actually intrigued about this. Losing a cordless grinder is not cheap!

[@deidjera]

Joseph Townsend yup, damn thieves everywhere.

[@stanislavtihohod]

Everything is better with bluetooth!

[@terryinozland]

8 mths later and i just bought mine at Bunnings last week and it's not this model at all. It works great but it's definitely not Bluetooth nor did they indicate I'm buying an old " model. Not that it's a problemo because I'm old now too ✓✓✓✓✓>50's.

[@OZToolTalk]

TERRY MAGGACIS bummer :/ It may not necessarily be the ‘older’ model but bosch (and all brands) will have multiple models. Bunnings do often also have their ‘own’ models. All Bosch blue grinders are good regardless but this one is particularly impressive. I hope it works out for you mate. (Mike)

[@OZToolTalk]

[Dwain] If it looks like this one except for the display panel on the top, then it's got the same power, safety features etc.

[@smokesmypaparazi]

Worth the coin?

[@smokesmypaparazi]

tuck your shirt in.

[@OZToolTalk]

no

[@smokesmypaparazi]

Oz Tool Talk you ever seen what a grinder does when when it gets caught in you clothing. It almost lets the spaghetti out.

[@OZToolTalk]

I thought you were just implying I'm a slob ;) Thanks for the safety reminder.

[@smokesmypaparazi]

Oz Tool Talk all good. Seen it happen twice, one with a corded 5 inch and the other with a 7 inch, you dont forget those images.
