The traditional Hilti tools are awesome. Very tough, and made in Europe (Luxembourg).
Used one of their drills years back on a rewire project that involved cutting holes through concrete blocks for waste pipes, and it was way ahead of anything else I'd used!
A word of warning though! I was told that their 'lower end' tools are now made in the Far East! Whether these are half decent tools, or the usual Chinese shite that Hilti have whored out their name for, just be aware that buying a Hilti doesn't necessarily mean you are getting what you think!
In the USA, when Hilti tools first started showing up in Home Depot, which I think might have been around 2000 give or take, most of the tools were manufactured in Europe. Basic drills, grinders, hammer drills, and the laser measuring tools were manufactured in Germany, along with some consumables. Some other items including some of the cordless tools and nailers , etc., were from Switzerland. The really expensive rotary hammers, and what might be described as "flagship" tools that had innovative features that weren't common the same type of tool from other manufacturers usually seemed to be manufactured in Liechtenstein. Some cordless tools may have been manufactured in China, but it was a very small portion of the tools.
Home Depot dropped the Hilti tools in store near the end of 2012. By that point "new improved" models of a lot of the tools had been introduced that were priced far closer to what the other professional brands like Milwaukee and Dewalt. Many of the new models had dropped some or all of the innovative features found on the older models. Most of the newer tools were also made in China. The Chinese made tools even included some of the older models like the smaller rotary hammers and powder actuated nailers.
I believe almost all of the cordless tools were by that point made in China, but this supposedly has to do with some joint venture with Panasonic. The prices on the older models Hilti was still manufacturing either stayed the same or went up.
After switching over to the Chinese manufacturing Hilti then parted ways with in store sales at Home Depot, although you can still buy the tools online, and Home Depot still has the best prices I've found.
Some of the higher end tools and accessories are still manufactured in Europe. This includes the ultra expensive stone cutting and grinding tools, breakers, probably and some of the larger rotary hammers. Some of the more expensive angle grinders were still manufactured in Germany. Hilti may have switched suppliers for their laser tools since they just went into some partnership with a specialist in that area, so I have no clue were those are manufactured.
When I checked some of the European sites, some of the flagship tools that had been discontinued in the USA were still being sold, but the prices were sometimes twice what they would now cost in the USA. I've lost a bunch of confidence in the brand, but maybe the Chinese made tools are just as good quality as the older tools.
