Value Collection NS06266381 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06266381 is an O1 oil-hardening tool steel flat stock bar measuring 1 inch thick, 3 inches wide, and 36 inches long. Manufactured to AISI Type O1 specification, this flat stock is a general-purpose tool steel widely used in toolmaking, die work, and precision machining applications. It ships in annealed condition and is intended for heat-treating after final machining. The 30.94-pound bar holds tight dimensional tolerances, making it suitable for applications where precision stock removal and dimensional predictability are required before hardening. Machinists, toolmakers, and industrial maintenance shops are the primary users of this material.

O1 tool steel flat stock in this size is commonly used in the fabrication of cutting tools, punches, dies, gauges, jigs, and fixtures where moderate wear resistance and good toughness after heat treatment are needed. The 1-inch thickness and 3-inch width make this bar appropriate for medium to heavy tooling work in job shops, tool-and-die operations, and maintenance departments running manual or CNC machining equipment. It is suitable for both small-run production tooling and prototype work where close-tolerance blanks are required.

Key Features

• AISI Type O1 oil-hardening tool steel meets standard material specification for predictable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches supports precise machining before hardening
• Width tolerance of plus 0.005 minus 0.000 inches ensures stock is never undersize on width
• Length tolerance of plus 0.5 inches provides adequate cut allowance for squaring operations
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Single-piece packaging with no minimum order multiple requirement for flexible procurement

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat stock suitable for use in toolmaking, die making, and general precision machining applications requiring an oil-quench hardenable steel in bar form.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. All heat-treating operations, including hardening and tempering, should follow established AISI O1 time-temperature guidelines and be performed in a controlled atmosphere or with proper scale protection to maintain surface integrity. Secure the workpiece properly before any cutting or grinding operation. Personal protective equipment including eye protection, gloves, and hearing protection should be worn during all machining and material handling.
