Sunnen Acquires Long-Time Partner Hommel Präzision

A partner since 1950, Hommel Präzision has represented Sunnen Products Company and its comprehensive line of bore finishing equipment, tools and accessories in Cologne, Germany. As of January 2023, the company will continue its mission of providing honing and deep hole drilling solutions as a wholly owned subsidiary of Sunnen.

January 2023 – St. Louis, MO – Sunnen Products Company has acquired Hommel Präzision, a former division of the Hommel Gruppe and a leading provider of honing and more recently, deep hole drilling, solutions in Germany for more than 70 years. Since 1950, Hommel Präzision has been the exclusive sales and service partner of Sunnen in Germany. The company’s sales and technical service teams will all remain the same – further augmented by the service and support of the Sunnen Global network. Closing was on January 3, 2023.

“Hommel Präzision is a well-respected, customer-focused organization and we are happy to have them as an official part of Sunnen,” said Chris Miltenberger, President, and CEO of Sunnen. “Our customer base benefits directly from the in-country sales and technical support capabilities.”

Honing has proven itself for decades as an alternative to internal grinding, fine turning, reaming and roller burnishing. Through its decades-long affiliation with Hommel Präzision, Sunnen is an established leader in Germany for honing components for the metalworking industry. And, as a systems manufacturer, Sunnen offers all the necessary tools, fluids, gages and accessories from a single source and not just honing, but more recently, in the past few years has provided a full line of deep hole drilling solutions, including machinery and the cutting tools to support them.

Sunnen’s bore finishing solutions include vertical and horizontal honing machines for single and series production; automated honing machines as processing cells or multi-linked systems; single and multi-spindle, modular honing machines with maximum variability; portable hand-honing devices for complex workpieces and individual parts; and a wide range of grinding strips, honing tools, honing oils, bore gages, and tools for third-party products. Sunnen’s deep hole drilling line of products includes deep hole drilling and skiving and roller-burnishing machines, cutting tools, cutting inserts and accessories.

Sunnen’s world headquarters and main manufacturing plant is in St. Louis, Missouri, with additional sales and manufacturing facilities in 14 countries spanning the globe. Total employment is over 700 worldwide. For additional information on Sunnen bore finishing solutions, tools and abrasives, contact: Sunnen Products Company at or visit
