What is different between sawing and broaching?

Rotary Broaching is a method of producing both internal and external forms fast and accurately on the end of a workpiece. Rotary broaching makes it possible to very accurate forms within 0.0005 inches within seconds.

With rotary broaching not only can you produce standard shapes such as hexagons and squares but also shapes such as Double Hex Rotary Broaches, 6-Lobe Rotary Broaches, Serration Rotary Broaches, J500 Rotary Broaches, Spline Rotary Broaches, Involute Rotary Broaches, Torx Rotary Broaches, Double D Rotary Broaches and any other Special Design Required. Rotary broaches can be made to just about any size, English or Metric.

Some of the material that can be rotary broached is brass, aluminum and steel and can go as much as 2 inches deep.
