I thought we could systemize the 'other tool section' by manufacturer. I'll start with Bosch. To 'add' a machine one can open a reply by mentioning the machine first. I'll give it a try.

GBH 2-28 hammer drill w/ exchangeable chucks. Got this drill about three years ago, but it's only been used a few times, since i live in a wooden house. But it came in handy when i build a sub-structure for a deck. The drill sports a SDS plus-chuck as well as the garden-variety kind. The normal chuck opens up to 13mm. It has a hammer function with and without rotation and a normal drilling mode. It has 850 W input,stroke energy is 3,2 joule, frequency 4000bpm. Weights in at 3,2 kg, sans drill. It features a 43mm collar.

I like the GBH 4-32 VFR drill. It's light enough to use all day drills 10-20mm holes in the hardest materials powerfully & quickly, and chisels & channels both chased grooves or shallower gouges freehand. It will even make holes in brick up to 32mm, albeit slowly.
With 900w & an interchangeable jawed chuck too, it can holesaw like a champ even in seriously large steelwork. I've cut holes as large as 75mm in girders! It's probably still one of the most powerful SDS plus drills available, which places it firmly at the top of the heap of its peers in my opinion. Whilst it's performance will be somewhat lacking in comparison to larger SDS Max machines with their more aggressive pneumatic hammer mechanism, it has two distinct advantages over them all: firstly it's a true multidrill, with the power, speed, torque, ergonomics & interchangeable chucks required of a multitalented general construction drill, & secondly a reverse gear. Anybody that's had a big 25mm + bit stuck around a deeply embedded reinforcing rod will know what I'm talking about. No more vise-grips, no more vainly hammering a stuck bit out backwards with a lump hammer bashing the side of the grips. In fact, stuck bits are all but eliminated with a reverse gear!
I should also add that with it's "L" shaped motor/drive mechanism it's also one of the few drills short enough to fit between stud work for drilling cable & pipe runs along walls. The excellent clutch mechanism will likewise help prevent any wrist-snapping, face-smacking jammed bit torque reactions too!

All I can say is wow! Bosch are using the new Sanyo/Panasonic 21700 cells in their batteries too, offering 4.0, 8.0 & 12.0 AH capacities in their new ProCore 18v lineup. Yes, you read that right; 12.0 AH! Using the now familiar (but uncomfortably heavy) triple-row (of 5 cells/row) format as used by both Milwaukee & DeWalt for their lesser-grade batteries. Apparently the Bosch techs can squeeze a bit more juice into & out of these batteries by using the top 'o the range Sanyo 21700 cells, and carefully electronically matching all cells within each row. The result is a peak power delivery of 90!! amps! Using Ohms law, that equates to 1600 watts @ 18v, & an insane 3200 watts @ 36v. Given that most mains electric tools have a usual max. input wattage of about 2,000-2,200 watts (a very few, such as Mafell's LO65 router are as high as 2,500-2,600 watts), that's getting into 415 volt 3-phase territory in terms of input power. There aren't even any tools made that can absorb that kind of power yet. Likely, all that peak power availability allows adequate safety margins & "headroom" for the coming new generation of cordless site tools. It also likely to be extremely useful for high-capacity "deep cycle" household & industrial storage of solar & wind power, not to mention all those prospective automotive, transport & logistics applications that Bosch is currently spending billions of R&D Euros on. www.bosch-professional.com/gb/en/community/category/new-bosch-procore-18v-35ah-70ah-and-105ah-()-batteries/12910115-t/p2#/main
