Slater Tools expands its product line of Swiss-type, adjustment-free rotary broaching toolholders with the 0700 series, which has a 0.5" tool bore. It uses standard 0.5" inch shank and 1.75" overall length rotary broaches for polygon forms, and most are available from stock. The series suited for use on Swiss-type CNC machines and gang-style lathes.
Rotary broaching, also called hex broaching or wobble broaching, uses a precision tool to produce an internal form inside a pre-drilled hole or an external form on the outer diameter of a machined part. Maximum toolholder life requires precision alignment with the pre-drill or diameter. The result is a form which matches the shape of the broach. For instance, an internal square broach measuring 0.25" across the flats produces a square hole of the same size. The company’s broaches are available with squares, hexagons, splines, serrations and other polygon forms.
