Frequently Asked Questions

Can you make a Rotary Broach for an SAE J500 48 tooth Spline?

We can make 48 tooth broaches at Polygon Solutions Inc., however some of the SAE major and minor diameter sizes result in too much tooth height for rotary broaching. Give us a call with your major and minor diameter and we'll let you know. Depending on your application, some internal involute splines can be altered by increasing the size of your pilot hole, and then relying on the remaining form for engagement or, milling the form first and then using the rotary broach as a finishing tool.

Standard forms specified as SAE J499, J500 and J501 are generally understood to be technically obsolete for design of new applications. However, it is listed for those existing applications where it may be required and broaches must be made for mating or repair parts. For the design of new applications, consult the ANSI B92.1 Involute Splines and Inspections Standard.
