Milwaukee recently showcased a new sub-compact cordless M12 1/2″ SDS Plus rotary hammer at their 2012 New Product Symposium event.
Milwaukee engineers are definitely ambitious with some of their M12 cordless tool designs – this became clear back in 2010 when they first released a 12V hammer drill. While I would never use the M12 hammer drill for extended masonry-drilling sessions, it works great for occasional holes. Thew new rotary hammer looks to be a perfect complement for extended or larger-bore drilling applications.
While the M12 rotary hammer is so small it seems almost toy-like, it can definitely hold its own against beefier tools.
There was a testing station at the media event, where we were encouraged to test out the M12 rotary hammer alongside an 18V hammer drill and an 18V rotary hammer. Although we’ll still need to test out the rotary hammer under our own conditions as well, the experience showed that the M12 is no weakling despite its smaller size and lesser weight.
The M12 rotary hammer is designed to handle SDS Plus drill bits up to 1/2″, but it could probably go past that although with greatly dimished performance. According to a handy reference chart, 4 out of every 5 holes drilled in masonry are with 1/2″ or smaller bits, meaning that the new compact model could handle up to 80% of all masonry-drilling tasks.

The rotary hammer is available as part of a 2x M12 XC battery kit (model 2412-22XC), or as a bare-tool (model 2412-20).
