Looks like a 90* rotary attachment with chuck. Most likely custom made to attach either an arbor with a 0.025 slotting mill, or rotary blade or something similar?

It's a technique known as mill sawing.

Video is fuzzy, but it looks like a standard right angle head to me. They're off the shelf from a few suppliers. It uses the machines spindle to spin a secondary collet chuck. They use them at Taylor, and I know I've seen some other builders with machining centers using them as well.

They tend to be pretty pricey; in the $3500 range last I checked. I've also heard that they don't last all that long in production, requiring a rebuild after a few months. If you were set on that method, I'd recommend getting a head made with a small spindle in a frame running the saw to get around the gears.

I'd recommend using a high speed turbine spindle and a small end mill, as the startup / maintenance costs are much lower and you can make blind slots as well. It's not quite as fast as a saw being optimally used, but you can slot with a turbine faster than he's slotting with a saw in that video.
