Drill Rod Tool Steels 03720141 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03720141 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require a dimensionally consistent, warp-resistant steel blank ready for machining and heat treatment. This piece measures 0.75 inches thick, 4 inches wide, and 36 inches long, and ships at approximately 31.54 pounds. A2 tool steel is an air-hardening grade known for its good dimensional stability during hardening, moderate toughness, and wear resistance, making it a standard choice for dies, punches, forming tools, and similar toolroom applications.

This flat stock is suited for job shops, tool and die operations, and maintenance machining environments where stock must be cut to size, machined to a near-net shape, and then heat treated. The 36-inch bar length provides practical yield for multiple tool blanks from a single piece. The pre-ground flat stock format reduces initial stock removal time compared to hot-rolled bar. It is appropriate for both short-run production tooling and one-off prototype tooling applications.

Key Features

• A2 air-hardening tool steel grade for reduced distortion during heat treatment compared to oil-hardening grades
• Thickness tolerance of +0.010 to +0.015 inches for consistent stock removal planning
• Width tolerance of +0.010 to +0.015 inches
• Length tolerance of +0.250 to +0.500 inches
• Square tolerance of +/- 0.003 inches for reliable squareness reference during layout
• Single-piece minimum order quantity for low-volume toolroom procurement

Compatibility

Designed as a standard A2 tool steel flat stock blank suitable for dies, punches, gauges, forming tools, and other toolroom components requiring air-hardening tool steel per AISI A2 material specification.

Installation Notes

Machining and heat treatment of A2 tool steel flat stock should be performed by qualified machinists and tool and die makers familiar with tool steel handling procedures. Follow the material manufacturer's recommended preheat, austenitizing, and tempering cycle for A2 grade before placing hardened tooling into service. Always allow the bar to reach thermal equilibrium before precision layout or grinding operations. Proper personal protective equipment, including eye and hand protection, is required when cutting or grinding tool steel stock.
