Internal broaching requires a starting hole or opening in the workpiece so the broaching tool can be inserted.
For internal broaching, the length of a broach in relation to its diameter may determine whether it must be pulled rather than pushed through the workpiece, for a broach tool is stronger in tension than in compression.
Vertical internal broaching machines are table-up, pull-up, pull-down or push-down, depending on their mode of operation.
