Drill Rod Tool Steels 85998722 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85998722 is an A2 air-hardening tool steel flat stock bar sized at 2 inches thick, 2.5 inches wide, and 18 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and its balance of toughness and wear resistance. This flat stock is supplied to tight tolerances - plus or minus 0.001 inches on thickness, plus 0.000 to 0.005 inches on width, and plus or minus 0.062 inches on length - making it appropriate for precision tooling, die making, and machined component fabrication. It is typically processed by tool and die makers, machinists, and metalworking shops.

This flat stock is suited for cold-work tooling applications including punches, dies, gauges, jigs, and fixtures where dimensional stability during hardening is a priority. A2 tool steel performs well in applications requiring moderate toughness combined with good abrasion resistance. At 18 inches in length, this bar supports single-component blanking or short-run tooling work without the need to cut down a longer stock piece. It is appropriate for both job shop and production tooling environments.

Key Features

• A2 air-hardening tool steel composition for excellent dimensional stability during heat treatment
• Thickness tolerance of plus or minus 0.001 inches for precision fitment in close-tolerance tooling
• Width tolerance of plus 0.000 to 0.005 inches for consistent mating to machined housings and die sets
• Squareness held to 0.003 inches edge and 0.004 inches per inch of thickness at ends
• Ready-to-machine flat stock format reduces prep time compared to round or irregular bar stock
• AISI A2 material specification meets standard cold-work tool steel requirements

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock suitable for cold-work die and tooling fabrication applications per AISI material specification A2.

Installation Notes

Machining, grinding, and heat treatment of A2 tool steel should be performed by qualified tool and die makers or machinists familiar with air-hardening steel procedures. Follow appropriate shop safety protocols when cutting or grinding, including eye and respiratory protection. Heat treatment cycles should reference the applicable A2 steel data sheet for austenitizing temperature and air-cool quench procedures. Do not attempt to flame-cut or weld without consulting A2-specific procedure guidelines, as improper thermal processing can compromise material properties.
