Drill Rod Tool Steels 03719689 A2 Flat Stock 3/8x4.5x36

Product Description

The DRILL ROD TOOL STEELS 03719689 is a length of AISI A2 air-hardening tool steel flat stock cut to 3/8 inch thick, 4-1/2 inches wide, and 36 inches long. A2 tool steel is an air-hardening, cold-work grade known for its dimensional stability during heat treatment and good wear resistance after hardening. This flat stock is supplied in an annealed condition, ready for machining to final shape before hardening. It is used by tool and die makers, machinists, and maintenance shops to fabricate punches, dies, gauges, and precision tooling components. The piece weighs approximately 18.08 pounds.

A2 air-hardening flat stock at this size is a standard starting blank for cold-work tooling applications in job shops, production toolrooms, and maintenance-and-repair operations. The 36-inch length provides adequate material for multiple smaller blanks or a single full-length tool. The 3/8-inch thickness suits thin die plates, blade stock, and similar flat tooling. The 4-1/2-inch width accommodates moderately wide die sections without requiring profile grinding from a larger bar. This stock is intended for machining, grinding, and heat treating by qualified tool and die personnel or experienced machinists.

Key Features

• AISI A2 air-hardening tool steel - stable dimensions during heat treat with reduced warpage versus oil-hardening grades
• Thickness tolerance of plus 0.010 to 0.015 inches for consistent stock removal planning
• Width tolerance of plus 0.010 to 0.015 inches
• Length tolerance of plus 0.250 to 0.500 inches
• Square tolerance of plus or minus 0.003 inches for predictable setup on surface grinders and milling machines
• Supplied in flat stock form at a single piece quantity - no saw cutting required to break a longer bar

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat blank suitable for cold-work tooling, die making, gauging, and general precision toolroom applications where dimensional stability during air hardening is required.

Installation Notes

A2 tool steel flat stock is machined and ground by qualified machinists or tool and die makers before heat treatment. All rough machining should be completed prior to hardening; finish grinding is performed after hardening and tempering to final hardness. Follow the steel producer's recommended heat treatment cycle for AISI A2, including a proper preheat, hardening temperature, air-quench, and double-temper. Wear appropriate PPE and follow shop safety procedures when cutting, grinding, or heat treating tool steel.
