Diehl Tool Steel, Inc.
Tool Steel Supplier Since 1926
In 1926, Albert Diehl founded Diehl Steel in Cincinnati, Ohio to service the needs of one of America’s largest machine tool hubs. Developed from a tool and die background, “Big Al” Diehl knew the importance of responsive, efficient service coupled with high-quality products. After 90 years in business, that tradition of excellence continues today.
Forever forward thinking, Diehl Tool Steel has become an international supplier of quality tool steel, alloy steel, mold steel, carbon steel, stainless steel, CPM powder metal, aluminum pieces, and customized machining services. Our products are used in thousands of manufacturing applications – from large-scale automotive and aerospace producers to a multitude of small businesses across the USA. No matter the size of the company, we deliver the highest quality steel products, on time, to your exact specifications.
We offer not only standard cuts, but custom cut and machined sizes for tool steel flats, bars, squares, sheets, plates, rounds, drill rod, and hollow bar. Our focus is, and has always been, to service the rapid turn-around needs of the tool and die, mold shop, machine shop, and OEM industries.
The natural result of such commitment is that in-stock material ships in as little as 24 to 48 hours.
