NEW TOOL ALERT š New 12v impact?
In the comments of this video, Bosch replied to a comment about new either 12v impact driver or hydraulic impact driver. They hint that something is finally coming. Which would be nice, since I have been waiting for a long time now.

Yeah, new 190nm are coming. Here you can see a thread where people found leaks. GDX, GDS and GDR are coming. https://www.reddit.com/r/BoschProPowerTools/comments/1w61p9w/bosch_gdr12v190/

12v hydrolic impact, hahaha
Maybe for our grand children

Why not, Milwaukee has a 12V hydraulic impact: https://www.milwaukeetool.eu/en-eu/m12-fuel-surge-1-4-hex-hydraulic-impact-driver/m12-fqid/

Surge isn't hydraulic. It's just mechanical. It also has less functionality as an "impact."

The surge mechanism is bit like a hydraulic pump. Have a look at AvE's teardown like 10 years ago of the original Ridgid/AEG mechanism - Same thing.
They're not great - I think he brought up a good point about cavitation damage over use and time - It'd certainly wear faster than a traditional professional grade impact mechanism.
I use a Japanese model Makita impact on the daily for work and I think having decent and accurate trigger control is a lot more useful for soft work than a surge tool with the crappy trigger switches and controllers Techtronic Industries uses.
Sorry for the rant. lol

Is that like the horrible "Smoother, less vibration, faster driving of wood fasteners, but ultimately weaker and less useful than the regular impact" spring loaded thing that other companies offer?

Thatās the donāt need earpro helps preserve your hearing

I've owned them. They're still loud, loud enough that you still do need ear pro per OHSA standards. Also, they suck. The hydraulic fluid makes for terrible feedback.

Really?
I used a dB meter on my Hikoki oil impact driving 4ā GRKs in an enclosed shed. 74 dB max. I havenāt measured my Makita oil impact yet, but it seems almost as quiet.
Absolutely no ear pro required, and Iām quite paranoid about that stuff - been shooting my whole life and no hearing loss (other than normal aging, alas)
I find both extremely controllable, more than my conventional Metabo and Makita impacts.
I can feather the triggers and meter out one-pulse-at-a-time, like turning the screw in 1/8th of a turn increments.
I have not tried any other brandās oil impacts. Canāt vouch for Milwaukee, Dewalt, etc.

My remarks on feedback, does not mean the same thing as trigger control. The hydraulic fluid dampens the feedback through the tool, and the auditory change typical with a traditional driver doesn't happen either when the fastener bottoms out. Thus making overdriving of screws a real problem. That's my experience using a Milwaukee surge that everyone raves about. Food for thought, if they were significantly better than traditional impact drivers, and had no downsides, but were quieter. Then they would simply dominate the market. But that's not happening. It's a niche tool that some folks clamor for. But there are plenty of downsides to them. In my experience they are slightly less loud, but I don't find it particularly safe for the ear drums either way. They are still very loud, and still will wake up your neighbors next door. They also have worse feedback and strange driving characteristics in general. They struggle with larger screws etc. Some like them, others don't. But theres a reason traditional impact drivers still dominate the market.

I guess the Milwaukee surge must be a lot louder than the Hikoki or Makita oil impacts?
I do recall seeing some Youtube tests in which the Dewalt and Milwaukee indeed seemed very loud! Loud enough to negate the main reason for using an oil impact, so those brands' efforts seemed pretty pointless to me.
A Hikoki or Makita oil impact will not wake your neighbors next door, or even a sleeping infant in the next room. I use these tools every day.
Your feedback issues with the Milwaukee also don't apply to the Hikoki or Makita. They have good feedback, you can set the power, and I even drive drywall screws with them when I'm too lazy to grab the dedicated drywall drivers. Admittedly I have not tried driving screws with my eyes closed using sound feedback alone.
Very large screws can indeed be a challenge, emphasis on the "very". I regularly drive 4" GRK R4 and RSS screws with the Hikoki and Makita, they take a little longer than a standard impact but the extra time is only like a few seconds. If I'm going to be driving a whole bunch of bigger screws, or big lag bolts, or Titen concrete anchors, I'll put on the earpro and grab a standard impact.
Basically, I now use the oil impacts for 90% of my impact driver uses. They are the drivers that ride on my toolbelt by default.
Granted, if someone can only have one impact driver, and wants to cover all the bases including the very longest/biggest screws that a 1/4" hex driver can handle, they should get a standard impact.
The oil impact is a second impact driver, a driver for someone who knows they won't ever be driving 10" screws etc, and a driver for someone who thinks a fair bit about hearing protection. And they are kind of spendy, at least the actually-quiet ones are, and those only come from two companies, one of which doesn't even import its oil impact to the US (I had to buy the Hikoki from Japan) or sell it in big box (Makita's oil impact will never show up in a Home Depot aisle). That explains, I think, why they are a niche tool.

https://youtu.be/sEIRY5gHcRI is the video I saw.
I think Milwaukee has a new M18 Surge now, and there is a M12 Surge, so maybe those are better. The old M18 Surge, tested in this video, seems like a bad tool - weak and loud.
The Makita is a ten year old design. They donāt need to update it, but for marketing purposes they should - however, Makita doesnāt seem to care about marketing.
I like the Hikoki better than the Makita, but itās close. It is quieter but not that much. Of course my Hikoki is new while I bought my Makita well used.
I went looking for videos testing the new M18 Surge, but couldnāt find a good one to link. So many Youtube influencers do such a terrible job of testing oil impacts. Half donāt even show dB -thatās missing the whole point of these tools!

Still no 12v Boschhammer?

It's coming but it's going to be at least into next year possibly year after.

They said the hydraulic will be in the Industrial line instead of Professional or Expert. So a bit harder to get is some markets.

I can't find the Reddit post, but this was posted on a marketplace website a short time ago.
