Starrett 54314 O1 Tool Steel Flat Stock 1/8x8x36

Product Description

The STARRETT 54314 is an O1 oil-hardening tool steel flat stock bar used in precision toolmaking, die work, punches, and custom tooling fabrication. Manufactured from AISI Type O1 tool steel, this flat stock measures 1/8 inch thick, 8 inches wide, and 36 inches long, with a weight of 10.21 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy is critical before and after heat treatment. Machinists, toolmakers, and metalworking shops rely on O1 flat stock as a starting material for tools that will be oil-quenched and hardened in the field or shop.

This flat stock is intended for shop and industrial use where a versatile, readily machinable tool steel is required prior to hardening. Typical applications include blanks for cutting tools, gauges, dies, jigs, fixtures, and wear components. The 8-inch width and 36-inch length provide substantial material for larger tooling blanks or multiple smaller parts. It is well-suited to job shops, toolrooms, and production environments where O1 is the specified material grade.

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general toolmaking, die, and fixture fabrication applications requiring this alloy specification.

Installation Notes

Cutting, grinding, and machining should be performed while the material is in its annealed state before hardening. Follow established shop safety practices when sawing or grinding tool steel, including appropriate PPE and ventilation. Heat treatment and oil quenching should be performed by qualified personnel following recognized metallurgical procedures for O1 tool steel. Secure the workpiece properly to prevent movement during machining operations.
