Drill Rod Tool Steels 03717774 A2 Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03717774 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 0.125 inches thick, 1 inch wide, and 36 inches long, this flat stock is ground to close tolerances and delivered in the annealed state, ready for machining before heat treatment. A2 tool steel offers good dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and cutting tools where tight tolerances matter. Licensed machinists, tool and die makers, and precision fabricators are the primary users of this material.

This flat stock is suited for shops producing tooling components that require moderate wear resistance and good toughness after hardening. The 36-inch length accommodates most standard die and punch blanks without additional material waste. A2 air-hardening steel is commonly selected over oil-hardening grades when reduced distortion during heat treat is a priority. The stock ships in annealed condition and is machinable with conventional tooling before the hardening cycle.

Key Features

• A2 air-hardening tool steel with good dimensional stability through the heat treat cycle
• Ground flat stock with tight thickness tolerance of plus or minus 0.001 inches
• Width tolerance held to plus 0.000 to 0.005 inches for precise fitment
• Length tolerance of plus or minus 0.250 to 0.500 inches on 36-inch bar
• Square tolerance of plus or minus 0.003 inches ensures consistent cross-section geometry
• Delivered in annealed condition, machinable before hardening

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock suitable for punches, dies, gauges, and general toolroom applications where AISI A2 material specification is required.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate tooling for hardened or semi-hardened materials. Heat treatment, including air hardening and tempering, should follow the material supplier recommendations for AISI A2 tool steel and be performed by personnel familiar with applicable procedures. Always wear appropriate PPE when cutting, grinding, or heat treating tool steel. Verify dimensional tolerances after machining and before hardening, as some minor movement may occur during the heat treat cycle.
