Drill Rod Tool Steels 03718921 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718921 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, punch fabrication, and precision machining applications. Measuring 0.125 inches thick, 3.5 inches wide, and 36 inches long, this flat stock is manufactured to AISI Type A2 material specification. A2 tool steel is valued for its dimensional stability during heat treatment and its resistance to wear and deformation under load. The stock ships at approximately 5.06 pounds and is ready for machining prior to hardening. Licensed machinists, toolmakers, and metalworking shops are the primary users of this material.

This flat stock is suited for fabricating punches, dies, gauges, jigs, and fixtures where consistent cross-section and tight tolerances are required. A2 air-hardening steel minimizes distortion during the hardening cycle compared to oil-hardening grades, making it a preferred choice for flat tool components that must hold their geometry after heat treatment. It is appropriate for both prototype and production toolmaking environments in job shops and manufacturing facilities.

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for general toolmaking, die-making, and precision machining applications requiring an air-hardening grade material.

Installation Notes

Cutting, grinding, and machining should be performed prior to heat treatment. A2 tool steel is air-hardened and should be processed by a qualified heat treater following appropriate temperature and atmosphere controls for the grade. Always use appropriate personal protective equipment when cutting or grinding tool steel. Consult applicable shop safety standards and material data sheets before processing.
