Drill Rod Tool Steels 06320121 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 06320121 is a precision-ground A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and machining applications. AISI Type A2 tool steel offers good wear resistance, dimensional stability during heat treatment, and moderate toughness, making it a reliable choice for punches, dies, gauges, and cutting tools. This bar measures 5/16 inches thick by 1-1/4 inches wide by 18 inches long and ships at approximately 1.99 pounds. Thickness and width tolerances are held to +0.010 to 0.015 inches, with a length tolerance of +0.062 inches and a squareness tolerance of +/-0.003 inches. Machinists, tool and die makers, and metalworking shops are the primary users.

This flat stock is suited for low-to-medium production tooling in job shops, tool rooms, and industrial maintenance environments. It is used to fabricate punches, forming dies, trim dies, jigs, fixtures, and wear plates where air-hardening steel is preferred over oil-hardening grades. The air-hardening characteristic of A2 reduces distortion risk during hardening, which is valuable when machining close-tolerance components before heat treatment. This bar size is appropriate for smaller tooling components and can be cut to length on a band saw or surface-ground to final dimensions prior to hardening.

Key Features

• AISI Type A2 air-hardening tool steel - reduces distortion during heat treatment compared to oil-hardening grades
• Thickness: 5/16 inches with tolerance of +0.010 to 0.015 inches
• Width: 1-1/4 inches with tolerance of +0.010 to 0.015 inches
• Overall length: 18 inches with tolerance of +0.062 inches
• Squareness tolerance held to +/-0.003 inches for precise fit-up in tooling applications
• Ready-to-machine flat stock format - suitable for sawing, milling, and grinding prior to hardening

Compatibility

Designed as a general-purpose A2 air-hardening tool steel flat bar for use in tool and die fabrication, fixture building, and precision machining applications requiring AISI A2 material specification.

Installation Notes

Cutting, grinding, and machining should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. Follow established heat-treatment procedures for AISI A2 tool steel, including proper preheat, hardening, and double-tempering cycles per the material specification. Always wear appropriate PPE when cutting or grinding tool steel. Consult the material manufacturer's data sheet for specific heat-treatment parameters before processing.
