Forge Your Future

Most people have no idea what honing or deep hole drilling is. Many of the products we rely on regularly would not be as safe, environmentally friendly, or as long lasting, if some of their critical parts were not honed.

The world runs on precision. Sunnen has recognized this need and been a leader in the bore sizing and finishing industry since 1924. From hydraulic pumps to landing gear to elevators – even medical and musical instruments—the parts we work with keep our world running smoothly and safely.

Join our team and work alongside leading manufacturers as you build a rewarding career.
