RBT offers on precision ground serration rotary broach tools. Serrations are fairly simple forms generally designed with multiple sharp teeth, and governed either by a major and minor diameter or by the angle of the tooth. Many serration forms can be made using rotary broaching tools in a lathe, mill or turning machine.
Various methods can be used to determine the dimensions required to manufacture a rotary broach with a serration form. The keys are to determine the major and minor diameter, angle of the tooth, and number of teeth.

Custom Form Rotary Broach Tools
Rotary Broaching has been one method used to obtain these various shapes. Common forms include hex broach, square, rectangle, torx, serrations, spline, involute spline, missint teeth, double d, double hexagon, double square, keyways, rectangle and triangle. Broach Sharpening, an external or internal broach tool can usually be sharpened one or two times if the tools are in reasonable condition. Only the front face will be re-sharpened with a cutting angle from 4 to 8°. The entire operation can be completed in a few seconds and can be generated to 0.0005 accuracy or better. Used for years on automatic lathes, Rotary Broaching has become the method of choice on Swiss Type machines, Mill, CNC lathes and Machining Centers because it eliminates a secondary operation.
