Gunner Omniturn question

Gunner, how rough on the machine is rotary broaching on an Omniturn GT-75, using 5C collets, broaching an internal 6 point spline of around .312
overall diameter through brass previously drilled with a pilot hole of the proper minor diameter? How about a larger spline, around .437, through 12L14 Ledloy? The broaching would reach about 3/8" into the hole each part. I would appreciate any comments you have on this.

Both should be just fine, if wobble broaching. The brass should be a snap... the larger one may be approaching the limits. Be sure your holes are deep enough for the broached material to migrate to. http://www.omni-turn.com/Pages/Tooling/Cutting%20tools/Somma/broaches.html
