Drill Rod Tool Steels 03718426 A2 Flat Stock 3/8x2x36

Product Description

The DRILL ROD TOOL STEELS 03718426 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require a reliable, dimensionally consistent blank for cutting tools, punches, dies, and fixtures. Cut to 0.375 inches thick, 2 inches wide, and 36 inches long, this flat stock ships in a ground condition with tight tolerances on all four faces. The A2 grade offers good wear resistance and minimal distortion during air-hardening heat treatment, making it a practical choice for medium-run tooling applications where dimensional stability after hardening matters.

A2 tool steel flat stock is used across job shops, tool and die operations, and maintenance departments in both light and heavy manufacturing environments. Typical applications include blanking dies, forming dies, gauges, punches, and precision fixtures. The 36-inch length provides sufficient material for multiple tool blanks from a single piece, reducing scrap and setup time. Installers and machinists working with this material will typically cut, grind, and machine to final form before sending out for heat treat or processing in-house.

Key Features

• A2 air-hardening tool steel provides low distortion during heat treatment compared to oil-hardening grades
• Ground flat stock with thickness tolerance of plus or minus 0.001 inches for tight dimensional consistency
• Width tolerance of plus 0.000 to plus 0.005 inches ensures predictable fit in close-clearance tooling setups
• Square tolerance of plus or minus 0.003 inches across the cross-section
• 36-inch bar length yields multiple blanks per piece, reducing material waste
• AISI A2 material specification meets standard tool steel classification requirements

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for general toolmaking, die making, and precision machining applications where A2 grade material is specified.

Installation Notes

Machining and grinding of A2 tool steel flat stock should be performed by qualified machinists using appropriate cutting fluids and tooling rated for hardened or semi-hard steels. Heat treatment, including hardening and tempering, should follow the material manufacturer's published parameters for AISI A2 and should be performed by a qualified heat treat facility or experienced in-house operator. Always wear appropriate PPE when cutting, grinding, or handling tool steel stock. Secure workpieces properly before any machining operation to prevent movement and injury.
