Drill Rod Tool Steels 03719663 A2 Flat Stock 3/8x3.5x36

Product Description

The DRILL ROD TOOL STEELS 03719663 is an A2 air-hardening tool steel flat stock bar measuring 0.375 inches thick, 3.5 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 is supplied in an annealed condition ready for machining, then hardened in air to minimize distortion. Machinists, toolmakers, and die makers use this material to fabricate punches, dies, cutting tools, and precision fixtures where tight post-heat-treat dimensional control is critical.

This A2 flat stock is suited for job shops, tool and die facilities, and in-house maintenance departments requiring cold-work tooling stock. The 36-inch length allows multiple blanks to be cut from a single bar, reducing scrap and setup time. The pre-ground flat surfaces support immediate layout and machining operations without additional surface prep. This material is appropriate for low- to medium-production tooling applications where toughness and moderate wear resistance are required.

• Supplied in annealed condition for straightforward machining prior to hardening

Compatibility

Designed as a general-purpose A2 air-hardening tool steel flat stock suitable for cold-work tooling, die components, punches, and precision fixtures where air-hardening material is specified.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment and personal protective equipment. Heat treatment should be performed by a qualified heat treater following the recommended austenitizing and air-quench cycle for AISI A2 tool steel. Always allow the bar to reach ambient temperature before measuring for final tolerances. Handle edges and ground faces carefully to avoid nicks that can initiate cracks during hardening.
