Q) What materials can I broach?

Q) I have nicks or skid marks on my chamfer, how do I eliminate this?
Reduce RPM's by 2/3 upon engagement of workpiece chamfer. After ½ way into chamfer increase RPM's to recommended speed maintaining same feed rate. If this does not improve condition or machine has no RPM control, re-chamfering part after broaching may be required.
Q) Why is my form twisted or gage stops short of going through?
All forms will have some degree of twist. Chip formation on end of broach tool causes a reduction in RPM's of the broach holder spindle, resulting in miss timing of RPM's. (workpiece to broach)
Q) Why does my part keep pushing back?
There are several possibilities:
Q) When mounted in a mill, why does my holder look like it is wobbling?
The holder is on a 1 degree angle, designed to reduce broaching pressure, which causes the holder to wobble. (Do not alter 1 degree angle)
Q) How do I remove chips from inside my part?
Q) What type of coolant do I use?
Broaching produces very minimal heat, therefore coolant is not a major requirement. Any water or oil based fluid is acceptable.
Note: When internal broaching, coolant could be trapped in front of tool causing inability to broach to full depth. If this occurs, turn off coolant or open pre-drilled hole larger to allow coolant to escape.
