Starrett 54194 O1 Tool Steel Flat Stock 0.75x3.5x18 in

Product Description

The STARRETT 54194 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Manufactured from AISI Type O1 tool steel, it measures 0.75 inches thick, 3.5 inches wide, and 18 inches long. Thickness tolerance is held to plus or minus 0.001 inches, and squareness is maintained at 0.003 inches per inch on all edges. These tight tolerances make this flat stock suitable for applications where dimensional accuracy directly affects finished tool performance. At 13.39 pounds, this is a substantial piece appropriate for heavy tooling stock requirements.

This flat stock is used in tool and die shops, machine shops, and maintenance departments where O1 tool steel is specified for its reliable oil-hardening characteristics. Typical applications include punches, dies, gauges, jigs, fixtures, and general tooling blanks. It is supplied in the annealed condition, ready for machining prior to hardening. Machinists and toolmakers working in job shops or manufacturing facilities are the primary users of this material.
