Drill Rod Tool Steels 85999274 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999274 is an A2 air-hardening tool steel flat stock bar measuring 3/32 inches thick, 1 inch 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 precision-ground to tight tolerances, making it suitable for fabricating dies, punches, gauges, and other tooling components. Machinists, tool and die makers, and metalworking shops are the primary users of this material.

This flat stock is used in tool and die shops, machine shops, and industrial fabrication environments where consistent dimensional accuracy is required before and after hardening. Its air-hardening characteristic reduces distortion compared to oil- or water-hardening grades, making it a practical choice for components that must hold tight fits after heat treatment. Typical applications include die plates, forming tools, and precision fixtures in light industrial and heavy manufacturing settings.

Key Features

Compatibility

Designed as a standard A2 air-hardening tool steel flat bar suitable for general tool and die fabrication applications requiring AISI Type A2 cold-work tool steel material.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. Heat treatment to full hardness requires a controlled atmosphere or vacuum furnace to prevent decarburization; consult a qualified heat treater for proper austenitizing and tempering procedures. Always wear appropriate personal protective equipment when cutting or grinding tool steel. Follow applicable shop safety standards and equipment manufacturer guidelines during all machining and heat-treatment operations.
