Dearborn Bortec was founded in 2002 by Howard K. Dearborn several years after he retired and sold Dearborn Precision Tubular Products. Advanced in years Howard felt the need to stay active in the industry. Howard K. Dearborn, was a pioneer in the machining industry, spending over 70 years developing special equipment and processes to accurately drill high precision small deep holes in highly specialized difficult-to-machine metal alloys such as Inconel, Beryllium, Titanium and others.
After working several years for his father Howard Dearborn started his first company, Howard Manufacturing Company, in Berea OH in 1941. The company name changed to Howard Dearborn Inc. in 1943. His company produced components for the war effort until the end of WWII. At the conclusion of the war he continued to fabricate components, predominantly for the military and energy industries. In the 1950s in order to produce specialized parts for the military and energy industries he designed and built special machinery enabling him to drill deep holes to exact tolerances previously unattainable. Howard fabricated prototype parts from difficult to machine metals including titanium, beryllium, zirconium and Inconel, for the USS Nautilus nuclear power reactor, and nuclear power plants in the US and Canada
