Brass hollow rods offers significant economic advantages, by way of removing the need for drilling operations, and very often the boring out of the parts.

Numerous applications, and in particular for the making of taps and valves (plumbing-heating industry), use many components that require the boring out of parts.

Industrial Application:- Widely uses in the automobile industry for synchronizer range and bearing cage and brass retainer.
