We get a lot of questions about rotary broaching in stainless steel. This video shows broaching of a custom shoulder bolt with a 3/8″ Hex in 416SS. The machine is a Haas TL-25 lathe and uses Polygon Solution’s GT Rotary Broach Tool Holder.

Rotary broaching any type of stainless steel can be very challenging, but we have many customers who do it and will do our best to try and help you succeed.
