Broaching is a metal-cutting process in which a broaching tool is pushed or pulled through a workpiece to remove material and form complex shapes. It is widely used for gears, holes, splines and keyways, making it one of the most established high-precision machining methods in modern manufacturing.

A typical linear broach consists of several functional sections along its length. Its overall size depends on the required cutting depth and the tonnage capacity of the broaching machine.

Shank
The pull end and slot allow the broach to be fixed securely into the broach holder.

Front Pilot
This section guides the broach into the workpiece and ensures concentricity as the tool enters the hole.

Cutting Teeth and Chip Breakers
The cutting area carries multiple rows of teeth. Roughing teeth remove bulk material while chip breakers control chip formation and improve cutting stability.

Rear Pilot and Finishing Teeth
The rear section contains finishing teeth that bring the final dimensions, tolerances and surface quality to specification.

The effectiveness of broaching comes from the progressive rise in tooth height along........
