Drill Rod Tool Steels 03720018 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03720018 is an A2 air-hardening tool steel flat stock bar cut to 0.625 inches thick, 3 inches wide, and 36 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good wear resistance. This flat stock is supplied in the annealed condition and is intended for fabrication of dies, punches, gauges, and precision tooling components. Machinists, tool and die makers, and industrial fabricators working with cold-work tooling applications will find this stock suitable for demanding forming and cutting tool applications.

This flat stock is appropriate for shops producing cold-work tooling, jigs, fixtures, and precision machine components that require a steel capable of through-hardening with minimal distortion. The 36-inch length provides a full bar suitable for layout and rough machining prior to heat treat. The 0.625-inch thickness and 3-inch width suit medium-duty die block and punch plate applications where A2 air-hardening properties are specified by the tool designer.

Key Features

• A2 air-hardening tool steel per AISI designation - minimal distortion during heat treatment compared to oil-hardening grades
• Thickness tolerance: +0.010 to +0.015 inches for consistent stock removal planning
• Width tolerance: +0.010 to +0.015 inches
• Length tolerance: +0.250 to +0.500 inches
• Square tolerance: +/- 0.003 inches for predictable squareness in layout
• Weighs approximately 19.8 pounds per bar - suitable for bench and machine handling without lifting equipment in most shop environments

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock suitable for cold-work die, punch, gauge, and general precision tooling fabrication applications where AISI A2 material specification is required.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified tool and die makers or heat treaters familiar with air-hardening cold-work steels. Always follow the material supplier recommendations for preheat, austenitizing temperature, and air-cool procedures specific to A2 steel. Secure the bar properly in the vise or fixture before machining to prevent movement. Inspect stock dimensions and squareness before beginning layout to account for the stated tolerances.
