Drill Rod Tool Steels 03720125 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03720125 is an A2 air-hardening tool steel flat bar supplied in a ready-to-machine blank. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good balance of toughness and wear resistance. This flat stock measures 0.75 inches thick, 3 inches wide, and 36 inches long, and weighs approximately 23.68 pounds per piece. It is used by tool and die makers, machinists, and metalworking shops that need a reliable starting blank for punches, dies, gauges, and similar precision tooling components.

This flat stock is suited for cold-work tooling applications in job shops, production tool rooms, and fabrication facilities. The air-hardening characteristic of A2 steel makes it appropriate for applications where tight dimensional control through the hardening process is required. Typical end uses include blanking dies, forming dies, trim dies, punches, and wear-resistant fixtures. The 36-inch length provides standard saw-cut blanks that can be further machined to final dimensions before heat treatment.

Key Features

• A2 air-hardening tool steel offers good dimensional stability during heat treatment
• Thickness tolerance of plus 0.010 to 0.015 inches allows for finish grinding to final size
• Width tolerance of plus 0.010 to 0.015 inches on the 3-inch face
• Length tolerance of plus 0.250 to 0.500 inches on the 36-inch dimension
• Square tolerance of plus or minus 0.003 inches for consistent cross-section geometry
• Single-piece minimum order quantity suits low-volume tooling and prototype work

Compatibility

Designed as a standard AISI A2 tool steel flat stock blank suitable for cold-work tooling applications where air-hardening die steel stock is specified.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified machinists or tool and die makers familiar with cold-work die steels. Always follow established shop safety practices when sawing, grinding, or milling tool steel, including appropriate PPE and machine guarding. Heat treatment should be performed per AISI A2 specifications by a qualified heat treater. Allow the stock to reach ambient temperature before measuring final dimensions after any thermal process.
