Serration Broaches — Custom Profiles to Drawing

Serration Broach Manufacturer in India

Q: What is a serration broach?

A serration broach is a precision cutting tool used to machine a series of parallel ridges (serrations) inside a bore. The serrations provide a mechanical interlock between a shaft and hub, transferring torque and preventing relative rotation. Serration broaches are used for steering columns, shaft couplings, aerospace fasteners, and anti-rotation joints.

Q: What is the difference between serrations and splines?

Splines are typically used for sliding or rotating connections and have a defined standard (DIN 5480, ASA B92.1 etc.). Serrations are generally used for press-fit, friction-locked, or anti-rotation connections and are often custom to the product design. Serration tooth profiles are usually triangular (V-form) while spline profiles are involute or straight-sided.

Q: Can you manufacture serration broaches to my drawing?

Yes. All serration broaches at SK Broach are manufactured to customer drawings. Please supply your drawing in DXF, PDF, or STEP format. We will review the drawing, confirm feasibility, and provide a quotation within 24 hours.

Q: What surface finish can serration broaches achieve?

SK Broach serration broaches can achieve Ra 0.4 μm surface finish on serration flanks. This is important for friction-fit connections where surface texture affects the press-fit holding force.

Precision serration broaches for fine-pitch serration profiles used in friction-fit and locking applications. Symmetrical and asymmetrical profiles manufactured to customer drawings in DXF, PDF, or STEP format. Ra 0.4 μm surface finish achievable.
