Rotary broaches, also known as wobble broaches, produce polygonal shapes in blind or through holes without the need for a secondary machining operation. They create minimal heat during the broaching operation, which helps prevent damage to the workpiece. They also require less pressure to form the shape than punch-style broaches. Compatible rotary broach holders and set-up plugs are used with the broaches to help improve accuracy during the broaching operation. Rotary broaches are commonly operated with lathes, milling machines, or machining centers in metalworking tasks.
