About Diehl Tool Steel Inc.

In 1926 Albert Diehl founded Diehl Tool Steel in Cincinnati, Ohio to service the tool steel needs of one of the countries largest machine tool hubs. Coming from a tool and die background, Mr. Diehl knew the importance of fast, efficient service and high-quality products. After 85 years in business, that tradition of service continues today.

Today, Diehl Tool Steel Inc. is an international supplier of quality tool steel, alloy steel, CPM powder metal, mold steel, carbon steel, stainless steel, aluminum products, and services.
