Drill Rod Tool Steels 86224102 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 86224102 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Measuring 0.375 inches thick by 1 inch wide by 18 inches long, this flat stock ships in an annealed condition ready for machining before heat treatment. A2 tool steel is known for its dimensional stability during air-hardening, making it a practical choice for punches, dies, gauges, and cutting tools. The bar holds a thickness tolerance of plus or minus 0.001 inches and a length tolerance of plus or minus 0.062 inches, meeting close-tolerance shop requirements without additional stock removal.

This flat stock is suited for machine shops, tool and die shops, and maintenance facilities where precision steel bar stock is needed for fabricating or replacing tooling components. The 18-inch length provides a useful starting blank for most bench or mill work. A2 material is commonly specified where moderate toughness and good wear resistance are required after heat treat, particularly in low-to-medium production tooling scenarios. Machinists and tool makers typically work this stock in its annealed state before sending parts to heat treat.

Key Features

• A2 air-hardening tool steel offers good dimensional stability during heat treatment
• Tight thickness tolerance of plus or minus 0.001 inches for close-tolerance tooling work
• Width tolerance of plus 0.000 to minus 0.005 inches supports precise fit-up
• Length tolerance of plus or minus 0.062 inches on 18-inch bar
• Square tolerance of plus or minus 0.003 inches across the section
• Ships as single bar with no minimum order quantity above one piece

Compatibility

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

Installation Notes

Machining and grinding of A2 tool steel flat stock should be performed in the annealed condition prior to hardening. Heat treatment including austenitizing and air quench should be performed by a qualified heat treater following recognized procedures for AISI A2 tool steel. Use appropriate personal protective equipment when cutting, grinding, or machining steel bar stock. Consult applicable shop safety standards for handling sharp-edged bar stock.
