Kadia Inc. has been the North American sales and service point of contact for Kadia GmbH since 1984. Beginning 2015, Kadia Inc. assumed the responsibility for all TBT Tiefbohrtechnik products in North America. With the addition of the TBT product line, Kadia Inc. also became the U.S. manufacturer of TBT carbide tipped gundrills. We manufacture, stock, resell, and regrind TBT deep hole drills here at our facility located in Brighton, Michigan.
Kadia and TBT Tiefbohrtechnik are both a part of the multinational Nagel Group.
Founded in 1966 in Dettingen a. d. Erms, the company specialised right from the outset in the manufacturing technology of deep hole drilling.
The company’s prime goal has always been to supply machines, tools, service and professional expertise from one source.
The company’s rise to market leader confirms that our customers appreciate this corporate policy. TBT combines the flexibility, dedication and customer-oriented approach of a streamlined medium-sized company with global presence.
