The Company was founded in the year 1954, in the city of San Pablo, industrial capital of Brazil, with the aim of manufacturing diamond tools to be introduced in the rising car industry. A few years later, in 1957, as a result of a Joint Venture with the North American Company Christensen Diamond Products, Christensen Roder is born, and devotes itself to the manufacturing of Diamond Bits for oil well and barrell coreheads drilling for oil and mining.

In 1994, Baker-Hughes enters this Joint Venture through the acquisition of Christensen Diamond Products. This new company had not considered an investments policy nor a manufacturing products policy in Latin America, and for this reason Christensen Roder Productos y Services de Petróleo Ltda., acquires the capital share from Baker, and assumes an independent position as regards the original Joint Venture. At present, Christensen Brazil is divided in two main sectors: Its Oil Division, whose main offices are in the city of Macaé and its Industrial Division whose main offices are in the city of San Pablo. Christensen Brazil has also got business offices all along Brazil, Italy, Chile and Mexico.

and sale of diamond bits to YPF in the regions of Mendoza, Salta, Neuquen, Río Gallegos and then at the Golfo San Jorge area, in Comodoro Rivadavia.
In 1981 Christensen Roder definitely establishes its Administrative Office and Repairs Central Workshop in the Province of Buenos Aires, locality of Don Torcuato. At the same time, and due to the industry growth, the company consolidated all along the country, opening services and administrative bases at the main oilfields in Argentina.

The same as in Brazil, since 1983, Christensen Roder Argentina S.A. has two divisions: the Oil Division and the Industrial Division.
