Drill Rod Tool Steels 02631067 A2 Flat Stock 3/8x12x36

Product Description

The DRILL ROD TOOL STEELS 02631067 is an A2 air-hardening tool steel flat stock bar measuring 3/8 inch thick, 12 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 and good wear resistance. This flat stock ships in an annealed condition ready for machining, and then hardens by cooling in still air after austenitizing. It is used by tool and die makers, machinists, and fabrication shops that require a reliable, versatile cold-work steel with tight dimensional tolerances. At 46.38 pounds, this is a full-size bar suitable for large die plates, punches, and fixtures.

A2 flat stock in this size is commonly used in the fabrication of blanking dies, forming dies, trimming dies, and wear-resistant fixtures in industrial and production shop environments. The 3/8 inch thickness makes it practical for medium-duty die plates and tooling components that require close flatness and squareness tolerances. This bar suits both small job shops and production tool rooms where consistent, repeatable results after heat treat are a priority.

Key Features

• A2 air-hardening tool steel - hardens in still air, minimizing distortion versus oil-hardening grades
• Thickness tolerance of plus or minus 0.001 inches for precise fitment in close-tolerance tooling
• Width tolerance of plus 0.000 to plus 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Square tolerance of plus or minus 0.003 inches
• Full 36-inch length suitable for large die sections or multiple blanks from a single bar

Compatibility

Designed as a standard AISI Type A2 air-hardening tool steel flat bar suitable for cold-work tooling applications including die plates, punches, and wear components requiring air-hardening heat treatment.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified tool and die makers or machinists familiar with cold-work die steels. Material should be stress-relieved before finish machining when close tolerances are required after hardening. Always follow the steel manufacturer's recommended austenitizing and tempering temperature ranges for A2 grade. Proper eye and hand protection must be used when cutting, grinding, or machining tool steel bar stock.
