Value Collection NS06124077 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06124077 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Manufactured to AISI Type O1 material specification, this flat stock measures 3/8 inches thick, 3/4 inches wide, and 18 inches long and weighs 1.45 pounds. Thickness tolerance is held to +/- 0.001 inches, making it suitable for applications requiring close dimensional control. O1 tool steel is known for its excellent edge retention after heat treatment and its ability to harden in oil quench, making it a standard choice for punches, dies, gauges, and cutting tools.

This flat stock is used by machinists, toolmakers, and metalworking shops in both production and job-shop environments. It is supplied in the annealed condition, ready for machining prior to heat treatment. Typical applications include blanks for punches, forming dies, woodworking blades, and precision gauges where consistent cross-section dimensions are critical. The 18-inch length provides enough stock for most single-piece tooling blanks or multiple shorter cuts.

• Supplied in annealed condition, ready for machining and subsequent oil quench hardening

Compatibility

Designed as a standard O1 tool steel flat stock blank suitable for general toolmaking, die making, and precision machining applications requiring AISI Type O1 oil-hardening material.

Installation Notes

Machining and heat treatment of O1 tool steel should be performed by qualified machinists or tool and die makers familiar with oil-quench hardening procedures. Always follow established shop safety practices when cutting, grinding, or heat treating tool steel. Proper personal protective equipment is required during all machining and heat treatment operations. Consult the material specification and applicable shop standards before hardening to achieve target hardness values.
