Welcome to Dearborn Bortec,
founded in 2002 by Howard K. Dearborn, a well-known specialist in deep-hole drilling. At Dearborn Bortec, we welcome standard machining jobs. In addition, we specialize in parts requiring operations not typically performed in other machine shops. Special operations include deep-hole drilling of single-hole or multi-hole patterns, inside finishing of long tubular parts and turning/boring of long parts requiring
large diameter hollow-spindle capability.

Located in Fryeburg, Maine our new facility is equipped with our own specially designed and built machines to accurately drill small deep holes in a variety of materials. With our larger
machines, we can perform conventional turning, drilling and boring operations on long parts, as well as perform deep-hole drilling.

Our machining specialists welcome the opportunity to assist our customers in overcoming product and process design challenges. We can accommodate most ferrous and non-ferrous metals including alloy steels, nickel-based alloys, non-magnetic materials as well as plastics.

Regardless of your application, we'd love the opportunity to quote your deep hole drilling needs. If you are not sure how to proceed with your project or if you are unsure whether or not deep hole drilling is the right solution for you don't hesitate to contact Dearborn Bortec first!
