Slater Tools Inc. now produces a series of external rotary broaches to fit its Swiss-Type internal rotary broach toolholders. The broaches can be used to manufacture precision- machined products and other microfastener products. Custom sizes and standard hexagonal forms as small as 1.5 mm are available. Diameter sizes ranging from 0.056" to 1" are offered.

Rotary broaching, also called wobble broaching, uses a precision tool to produce a form inside a pre-drilled hole or on the outside of a part’s diameter. The result is a polygonal form that matches the shape of the broach. Broaches are available as squares, hexagons, splines, serrations and other polygonal forms.
