Drill Rod Tool Steels 03718400 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718400 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require consistent dimensional accuracy in raw stock material. Measuring 0.375 inches thick, 1.5 inches wide, and 36 inches long, this bar ships at approximately 5.74 pounds. A2 tool steel is valued for its balanced combination of wear resistance and toughness after air-hardening heat treatment, making it a widely used choice for punches, dies, gauges, and cutting tools that demand dimensional stability through the hardening process.

This flat stock is suited for fabrication shops, tool and die operations, and maintenance departments that machine or grind raw bar stock into finished components. The 36-inch length provides enough material for multiple shorter blanks depending on the final part geometry. Close-tolerance ground surfaces minimize stock removal before final sizing. Applications include blanks for form dies, trim dies, punches, and precision fixtures in both production and prototype environments.

Key Features

• AISI A2 air-hardening tool steel for dimensional stability during heat treatment
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal planning
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Square tolerance of plus or minus 0.003 inches
• 36-inch bar length supports multiple blanks from a single piece

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock bar suitable for general tool and die fabrication applications where AISI A2 material specification is required.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with air-hardening steel procedures. Always follow established shop safety protocols when sawing, milling, or grinding tool steel bar stock. Heat treatment should follow published A2 hardening and tempering guidelines from a qualified heat treater. Wear appropriate personal protective equipment when handling or machining steel stock.
