In 1874 the Sibley Drill Press Company was founded by three men, Albert P. Sibley - Machinist, George Ware - Pattern Maker, and John R. Mills - Machinist, with the purpose of manufacturing and distributing drill presses. To support the manufacture of these drill presses, they found it necessary to integrate a foundry operation into the manufacturing organization. Once the foundry was in operation they began receiving numerous requests to manufacture parts other than for drill presses. Their customers in those days were well known companies like Studebaker, Oliver Plow, and Notre Dame University.

In the early 1950's the outside business far exceeded the drill press portion, so when numerical controlled machines were developed, Sibley exited from the manufacturing of drill presses and concentrated on the casting and machining portion of the business.

Sibley's core business involves the manufacture of gray, ductile and white iron castings and contract machining. With casting and machining capabilities encompassing 260,000 square feet, technical depth, state-of-the-art equipment, skilled and committed employees and administrative backup, Sibley is well placed to serve the demanding needs of its customers. Now well into its second century, Sibley Machine & Foundry Corporation continues to grow while providing a stable industrial job base in the community.
