Drill Rod Tool Steels 06316400 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 06316400 is an A2 air-hardening tool steel flat stock bar supplied in an annealed, ground condition ready for heat treatment. It measures 0.25 inches thick, 4 inches wide, and 18 inches long, with a shipping weight of approximately 5.43 pounds. A2 tool steel offers excellent dimensional stability during air hardening, making it a preferred choice for dies, punches, gauges, and precision tooling where tight tolerances and resistance to distortion are critical. Machinists, tool and die makers, and industrial fabricators work with this material in shop environments where controlled heat treatment will be performed after machining.

This flat stock is suited for toolroom and production applications requiring a medium-alloy air-hardening steel. Typical uses include blanking dies, forming dies, trim dies, shear blades, and precision gauging fixtures in both job-shop and production settings. The 0.25 inch by 4 inch by 18 inch piece size is convenient for smaller tooling projects or prototype work without the waste associated with cutting from full bar stock. AISI type A2 is the specification governing this material.

Key Features

• AISI A2 air-hardening tool steel for minimal distortion during heat treat
• Ground flat stock with close thickness tolerance of plus 0.010 to 0.015 inches
• Width tolerance of plus 0.010 to 0.015 inches for consistent fitment in precision layouts
• Length tolerance of plus 0.062 inches - provides slight oversize for face-milling to final length
• Square tolerance of plus or minus 0.003 inches for reliable squareness across the cross-section
• Ready-to-machine in the annealed condition prior to hardening and tempering

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock for use in any toolroom or fabrication application requiring A2 specification material in a 0.25 inch by 4 inch by 18 inch form factor.

Installation Notes

A2 tool steel flat stock is machined by tool and die makers and industrial machinists using conventional milling, grinding, and EDM equipment. All heat treatment - including hardening and tempering - must be performed by qualified personnel following AISI A2 recommended thermal cycles; do not attempt to air-harden without proper furnace equipment and temperature controls. Secure workpieces properly before any cutting operation, and wear appropriate PPE when grinding or machining. Verify final dimensions after heat treatment, as some minor movement may still occur.
