The broaching depth can be up to 1.5 times the dimension across the flats of the shape you want to broach. For example, you can broach a ¼" square hole up to 0.375" deep.
The material to be broached should not be harder than 200 Brinell. This means you can broach aluminum, brass, bronze, soft cast iron, and mild steel. In general, you are safe with any steel where the last two digits of the AISI number are less than 30.
The rotary broach tool holder is a lot like a live center. There is a bearing between the tool and the shank. But the tool is mounted at a 1-degree angle to the shank. So as the shank rotates, it "wobbles" the cutting tool. This 1-degree wobble advances each of the facet cutting edges in turn as the broach advances into the hole. The material that is removed curls into the bottom of the hole.
