Drill Rod Tool Steels 03719705 A2 Flat Stock 3/8x6x36

Product Description

The DRILL ROD TOOL STEELS 03719705 is an A2 air-hardening tool steel flat stock bar measuring 3/8 inch thick, 6 inches wide, and 36 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment, moderate toughness, and good wear resistance. This flat stock is used to fabricate dies, punches, gauges, and tooling components. It ships in the annealed condition, ready for machining prior to heat treat. Weight is approximately 24.08 pounds per piece. Thickness tolerance runs from plus 0.010 to 0.015 inches, and the bar is machined to close tolerances on all faces.

This flat stock is suited for tool and die shops, machine shops, and industrial fabrication environments where consistent cross-section and predictable air-hardening response are required. Typical applications include blanking dies, forming dies, trim dies, precision gauges, and wear-resistant tooling components. The 36-inch length provides flexibility for multiple part blanks from a single bar. Installation and fitment are job-specific based on the tooling design being produced.

Key Features

• AISI A2 air-hardening tool steel - stable dimensions during hardening, reduced distortion risk versus oil-hardening grades
• Annealed flat stock ready for machining and subsequent heat treatment
• Thickness tolerance: plus 0.010 to 0.015 inches for consistent stock removal allowance
• Width tolerance: plus 0.010 to 0.015 inches
• Length tolerance: plus 0.250 to 0.500 inches
• Square tolerance: plus or minus 0.003 inches for right-angle accuracy across faces

Compatibility

Designed as a standard AISI A2 tool steel flat stock suitable for cold-work tooling and die-making applications requiring air-hardening steel in a 3/8 x 6 x 36 inch flat bar form.

Installation Notes

Machining and heat treatment should be performed by qualified tool and die makers or machinists familiar with A2 tool steel procedures. All cutting, grinding, and EDM operations should be completed prior to hardening. Follow the steel manufacturer's published heat treat parameters for austenitizing temperature, soak time, and air-cool procedure to achieve target hardness. Grinding after hardening should use adequate coolant to prevent surface tempering.
