Now, CNC Broach Tool LLC has begun offering indexable carbide spline cutting inserts that fit its existing line of toolholders. These spline inserts can be used to punch broach internal and external involute splines in a CNC lathe or mill. Each spline insert has two cutting edges and are TiN coated carbide just like the stock standard keyway insert product line.

CNC Broach Tool LLC has been manufacturing indexable linear broach systems for broaching keyways in CNC machines for nearly 20 years. "Automating the broaching process makes it possible to broach keyways in blind holes within a CNC without the need to purchase big expensive broach equipment," said a company spokesperson. "It also allows you to combine offline broaching operations together within a CNC lathe or mill operation to save time and money."
