Re: HEX broach too big for our manual press

We have the same issue with the arbor press in our shop. Our solution was to start the broach using our lathe, which allows us to carefully align the broach to the hole and get the broach deep enough to now fit into our press. We try not to put too much load on the tool when it is in the lathe since we don't want to overload the lathe axially (which would damage the bearing in the lathe).

EDIT: The amount of load we put on the part+tool when they are in the lathe is very small - just enough to start 2-3 teeth of the broach - which is enough for it to then fit in our press.
