Oil & Gas

Dearborn leads the way in deep-hole drilling and precision machining of complex Oil & Gas components. For more than 60 years, Dearborn has been a key machined parts supplier to the world’s foremost energy service providers. In the quest to drill deeper, faster, and in increasingly harsh environments, today’s E&P technologies demand a level of precision which rivals that of the nuclear and aerospace industries.

Dearborn employs unique deep-hole machining capabilities, and our penchant for quality has made us a leading supplier for many oilfield service companies. Our depth of experience and broad "turn-key" machining capabilities make us the preferred supplier of high-precision machined components for today's premier oil-field service companies. Expertise in providing co-engineering for manufacturability, complete machining, wear surfaces, coatings, cladding, peening, logistics, to planning and procuring of raw material make Dearborn a full service solution.

Our specialty is drilling deep bores in high grade non-magnetic alloys such as MP35N, 718, 925, 17-4PH and titaniums. Our unique and specialized gun-drilling technology gives us the ability to produce fluid passages and wire-ways to depths and tolerances considered impossible by others in our industry. We are able to produce bores as small as ? .055", as large as ? 14.0” and in excess of 32-ft long.
