There is no Kress anymore. The production and so on continues under AMB-Elektrik with reduced portfolio. Some employees continue to work for AMB on the same premises.
I'm not sure if there is a license fee for CAS. My impression is Metabo makes the batteries puts the label on and sells them to the CAS partners. Some CAS partners basically sell Metabo in they're branding (color and label) not having a battery tool of they're own.

Haven't seen any adapters to fit CAS batteries yet, which is sad. Especially considering that it's still (arguably) the best battery available that could be used to fill the gaps with other manufacturers' larger tool ranges.
There's other German manufacturers that would benefit from the CAS "spreading the love" a little further. Level manufacturers like BMI &/or Stabila could have cordless modules on their current & future Lasers, just like DeWalt, Makita et. al. do. Wacker Neuson could do with cordless versions of their hex demolition hammers (are they actually Austrian?), although it appears that Milwaukee are already doing this with their new 72V battery platform. Maybe a mere 18 x 2 (36v) aren't sufficient for such high power demands?
Either way, a new 2 x 18V SDS Max cordless hammer is really needed on the CAS platform even if it's currently insufficient for larger hex breakers. Maybe a more specialist manufacturer of LED floods & site lights: Osram or another competitor? Given that longer runtimes & power is available from the latest batteries, it starts to open up possibilities.
Maybe just as Metabo's little 12V batteries are de-facto part of the CAS now, perhaps a newer "extreme power" pair of 10-cell & 20-cell 72V batteries rated @ 5.0 & 10.0 AH respectively are possible? Cordless cement mixers? Wacker-packers? Welders? Ditch-Witch, Bobcats or powered site carts?

Not really & yes, it is. In the 2nd link there's a Metabo battery to Hitachi tool adapter. The first I've seen! It's potentially a good thing: I've for some time rather fancied a Hitachi-Koki cordless Framing Nailer, but don't want another bloody battery system! Unfortunately it appears that they don't ship the confounded adapters to OZ! Sigh.
Yet I suspect that a CAS battery adapter will always be "problematic" due to the much-complained about tool-mounted battery release button. It's really never been an issue for me personally. In fact I've always had a lot of confidence with Metabo's battery mounting's security. Since the new interface I've never had a battery come off a dropped tool - which is more than can be said for many alternatives. No, I'm not in the habit of dropping tools willy-nilly, but, you know, shit happens. I always seem to have a good, secure & strong physical & electrical battery connection from CAS tools. Older Metabo battery interfaces, such as the rather insubstantial older gen. 18v & Powermaxx ones, Bosch, Makita et.al. - less so.
Given this, any 3D printed CAS battery interface adapter will necessarily have to include release/locking button & linkages. I'm dubious at best with this potential source of frustration & insecurity. Not saying it won't work well - I've not tried one of course (didn't even know they existed) - but I'm guessing it would work BETTER with battery-mounted release buttons like almost all other cordless tool manufacturers use.
As regards the second part of my post, I think on reflection that an entirely new interface will be required for super-duty cordless tools & machinery. Something that fits larger, more energy-dense, powerful & higher voltage cells such as the proposed Tesla "4680" high powered cylindrical cells perhaps? Something that requires a new generation of tools, interface, charger power & cooling & battery housing design to best take advantage of all this energy density when applied to traditionally mains (& petroleum)-powered tooling.
Cordless tech is currently advancing exponentially. Who knows what's around the corner?

It shows a CAS battery, but it's actually to put a Ridgid battery on a Hitachi / Metabo HPT.
It's worth putting up with an extra battery system for the framing nailer - I can't fault it.

Many users consider the Milwaukee equivalent to be superior. Personally, I wouldn't have a clue. I've only ever used Paslodes' gas & Bostitch air nailers. Plus there's a new Senco cordless electro-pneumatic framer out too!
They all seem to be a bit heavy, 'though. When I start whinging about big double-row batteries on cordless drills & their ilk being excessively heavy, then a 4-4.5 Kg battery framer is just getting a bit beyond the pale. Especially considering the weird & wild angles & arm extensions used when roof & sub-floor framing.

Got a couple of new Fein cordless - the 125mm paddle switch grinder (so I've got both of them now!), and an ASCM 18 QSW drill. Both excellent quality - I think the drill will quickly become my favourite!

After sticking with Fein for years with their corded multitools, I upgraded to the cordless supercut year before last, principally in an effort to reduce the spaghetti junction of extension leads and cables cluttering up scaffolding when I'm working on exteriors. I reckon I'm getting around 40 minutes runtime when using a standard 5.2 ah battery, though haven't tried the high power batteries yet. Since the success of this upgrade, I've got the 18V 125mm grinder, the ASB 18Q combi drill, the fast charger, 3 of the 2.5ah batteries and a couple of the high power 5.2ah batteries. These are replacing corded and cordless Metabo tools - my experience has been the Feins are better engineered, more powerful and offer more flexibility. The next move is to replace the Metabo 18v die grinder with the AGSZ 18-280 which like the grinder offers variable speed, and I'm hoping they'll bring out something I can replace my Metabo 18v band file with. I'm not expecting the Fein angle grinder is going to replace my corded grinder - even with the high power batteries, I'd be swapping them out too often to make it worthwhile, but for smaller jobs with sanding discs or metal cutting discs on it, it'll be useful. And in the meantime I'll still hang onto my metabo band file and caulk gun, they're both ok for the time being.

Shame Fein don't do a high handle/vertical motor SDS with extraction attachment... I need one and don't know what go with. I have the Makita but it's not very torquey, keeps binding and slowing; the Hilti TE6 A22 is very nice but very expensive; other option is the Bosch GBH 18-26... if Fein did one I'd get it in a heartbeat - top quality tools.

Makita died on me, less than 2 years old, maybe a warranty job, but I won't hold my breath... ordered the Bosch with dust extractor... another battery platform!

I'm trying Metabo's 18v version. Made in Germany. Seems like a pretty good alternative. The fan in the extractor attachment runs on for a few seconds after the trigger is released. It's fairly heavy in comparison to my mini Bosch ones (have 2 - one required repair after about 30,000 holes in structural concrete). But it's at least CAS battery-compatible. The mini-Bosch are about half the weight, & much better balanced, but lack extraction.
I've always had Bosch SDS drills. Tried a Metabo Multidrill years ago, & a Kango years before that. But the Bosch versions are "better". Best of all (corded) is the GBH4. Just a great allrounder with interchangeable chucks for worksite boring from about 12-25mm, chiselling & chasing. Also have an (old version) 36 V Bosch, which is also fairly versatile if a mite gutless, but lacks useful capacity beyond about 20 mm. Had it almost 20 years now - ultra reliable! Also won a GBH3 in a competition, but gave it away as the "4" is just so much better.
Plus a couple of Max drills. DeWalt & Metabo, 1500 & 1700 W respectively. Both are extremely powerful & bore 35mm holes (supposedly up to 52mm max) effortlessly, but are also much too heavy for chiselling &/or chasing above waist-height.
So I'm rationalising my drills down to the new Metabo cordless, the Bosch GBH4 & Metabo Max corded, which is a nice long inline format for breaking & digging with a clay spade. Might keep the old Kango 240 multidrill as a nostalgic backup too. The 2 x 18v Bosch minis, 36v Bosch, & SDS Max DeWalt will be going. The Bosch GBH3 & Metabo UHE28 went years ago.
The Metabo KHE96, also sold as a Milwaukee 950S & even an AEG something or other is still (1700w, 20J) the most powerful Max hammer that still drills (up to about 52mm/2")! Unfortunately, it's still lacking the necessary punch for bursting (or even efficiently flaking) hard bluestone boulders, of which I have plenty. An air hammer (& even TNT) is required for that task!
Whilst I haven't used the little Metabo KHA 18 LTX BL 24 Quick Set ISA (what a bloody ridiculous mouthful!) in anger yet, I can already tell that its much more powerful & heavy than the mini-Bosch tools are. It's also going to be a bit front-heavy too, but I won't be using it continually all day as I once did with the baby Bosches. The extraction adapter is removable, & helps a bit with the handling when removed. It's 4.8 KG (measured) all-in with extraction cassette & 8.0 AH battery! So unlike the baby Bosches its definitely a 2-handed tool. It's major redeeming feature is that it has CAS compatibility.
I still maintain that Bobbie Bosch manufacture the biggest & best range of corded & cordless SDS+ machines on the market.
PS Ive found that Hilti make the best small SDS+ bits: fastest by a huge margin. Hawera/Scintilla/Bosch make some of the longest lasting bits. Hilti's bits are much faster due to having a cruciform tip even in smaller sizes, which tends to snap off if it obliquely hits steel reinforcing bars. Standard cheap H/S/B bits have a cheaper twin cutter head in smaller sizes that tends to deflect away from reo bar. Above about 12mm most quality bits are cruciform, meaning boring speeds are similar.

I once had one the old Bosch GBH24VFR - very heavy 3ah battery - we're spoilt for choice now. I looked at the Metabo, but I've had too many problems with their cordless tools and it's too expensive.
The 18V-26F is 2,6joules, 3,4kg - has a -70% power mode too. I've not gone for ProCore batts, just the normal 6ah, from what I've read the extra bulk and weight don't add much to the run time for a drill...
I've been trying out the Bosch 7X bits, cruciform head, seem to be better than the standard Bosch bits.

I've not gone for ProCore batts, just the normal 6ah, from what I've read the extra bulk and weight don't add much to the run time for a drill... I've been trying out the Bosch 7X bits, cruciform head, seem to be better than the standard Bosch bits. The ProCore batteries are Bobbie Bosch's Li-HD equivalent: top quality matched arrays of hi-power 2170 Sanyo Panasonic cells. Should you require boring at or near the max recommended capacity of the drill, the additional current capability of these batteries may be useful. I'm unaware of the "7x" bits, but they're undoubtedly faster than standard bits. One thing that I've noticed with Bosch published specifications is that they have 2 distinct drilling ranges published for each model: Possible & Optimal ranges. My own little GBH18V-ECs quoted ranges are 4-18 & 4-10mm respectively. As the doubling of any given diameter actually quadruples the cross sectional area, & therefore the power required to any given depth of hole, larger sizes become exponentially more difficult for any drill. As I used mine specifically for drilling 5mm x 50mm deep Hilti Plug holes in structural concrete buildings for surface mounting cable ducts & electronic fittings, this little beast was/is ideal. I'd never even consider boring wider holes than the "optimum" 10mm unless in the softest of substrates. In fact, I'd consider the 18mm diameter "Possible" max to be wildly optimistic! Likewise, with your own choice I'd suggest that anything larger than the stated Optimum max of 16mm might be unnecessarily asking too much of your drill, especially the "Possible" max of 26mm. Yes, its possible, but it will also be slow & pretty hard on the tool too. You'd really need the extra power of those ProCore batteries to regularly exceed the recommended Optimum max in anything harder than soft clay brick. Even the inexhaustable power of the corded GBH4 has an Optimal max quoted of only 25mm (32mm possible max). This is all I've ever asked of it. For bigger holes (35mm was infrequently but regularly required) I always chose my 1500w (9Kg, 18J) DeWalt Max hammer. This tool was also the preferred option for brick removal, deep chases and lighter demolition work. I consider that battery hammers of most persuasions fall abysmally short for chiselling & chasing. All SDS + iterations that I've tried are pretty inefficient. Even the GBH4 (one of the more powerful SDS + hammers available) much prefers chasing between rather than through concrete bricks. For optimum chasing it's hard to ignore the SDS Max hammer's additional punch. I notice that Bosch now have a couple of cordless (18V!!) contenders in the 5 & 8 Kg classes. The addition of a 8.0 or 12.0 AH ProCore battery to each will necessarily add an extra 1-1.5 Kg to what is already a pretty heavy (& heavy duty) tool. Even then, I'd guess charge life will necessarily be rather short. I personally found that my 36V GBH 36 VF-Li Plus was a bit too compromised for continuous and intensive professional work. Batteries required frustratingly constant exchange (every 30-60 minutes, or 20 mins continuous chasing), which when accompanied with slow charging of an hour or so soon becomes untenable.

I doubt I'll use it for more than 16mm - main range I use is 5mm - 10mm into pretty hard structural concrete.
For the really light stuff, I have the 10,8v Makita, it has it's place - 1 joule can't do much!..
For the big stuff, I'll admit I like the look of the Bosch 18v SDS Max machines - but I have the 2x 18v Makita SDS Max, it has very low vibration, batteries last a decent time (and I have lots of them) - but I use it mainly for chiselling instead of drilling... it'll do for now.

The Fein hammer drill is, as far as i know, from Keyang. www.keyangtools.com/product/hd18bl-cordless-combination-hammer-battery-18v-5-0ah/That does not mean it' bad, I've never handled one and heard very little about it.
