The new Sunnen SHD-series bore-sizing machine incorporates the BTA Heller skiving and roller burnishing tooling. Sunnen expects the acquisition of Troy, MI-based BTA Heller to create a company unique in the industry, combining years of both deep hole drilling and honing expertise


Last year’s acquisition of the premiere deep hole tooling and systems manufacturer positioned Sunnen as a single-source for bore creation and finishing solutions, unique to the industry. Now, the company is moving the new division to the company’s long-time headquarters in St. Louis, MO. The move will allow further development of tooling, systems and processes for precision bore applications.

Sunnen Products Company is relocating its BTA Heller division to the Sunnen headquarters in St. Louis, MO. The move from Troy, MI will be completed by March 31st, with key personnel making the move. Sunnen’s acquisition of BTA Heller last year created a unique solution for shops looking for complete bore creation-to-finishing capabilities. Sunnen, the world’s largest vertically integrated manufacturer of honing systems for precision bore sizing and finishing, added BTA’s deep hole tooling and systems for primary hole generation. The move will facilitate further development of tooling, systems and processes, as the companies build on natural synergies to offer single-source bore creation and finishing solutions.

“Our companies complement each other very well,” says Chris Miltenberger, president and COO of Sunnen Products Company. “No other deep hole/BTA company has Sunnen’s global presence for customer, technical and post-sale support. The transfer of knowledge between the two companies has already created unique value propositions, and Sunnen’s strong sales and service network will deliver this expertise to our customers.”

Sunnen’s core technical competencies include automated and manual honing and lapping systems, custom system development and integration, abrasives, tooling, lubricants, and gaging. The BTA Heller acquisition expanded Sunnen’s industry leading honing expertise to include tooling for initial hole creation and other complementary bore sizing and finishing processes. Sunnen recently introduced the new SHD series skiving and roller burnishing system with tooling engineered and supplied by BTA Heller.

Sunnen employs 650 people worldwide, with offices, manufacturing and tech support facilities throughout Europe, the UK, China, Brazil and India. For additional information contact:
