Drill Rod Tool Steels 85999258 A2 Flat Stock 3/32x1/2x36 in

Product Description

The DRILL ROD TOOL STEELS 85999258 is an A2 air-hardening tool steel flat stock bar measuring 3/32 inches thick, 1/2 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 punches, dies, gauges, fixtures, and cutting tools. Machinists, tool-and-die makers, and industrial fabricators work with this material in tool rooms and job shops where repeatable accuracy and hardenability are required.

This flat stock is used in the production of cold-work tooling components across a wide range of industrial and manufacturing applications. Typical uses include die sections, form tools, jigs, and precision wear components. The 36-inch length allows multiple parts to be cut from a single bar, reducing setup time. The air-hardening characteristic of A2 steel means less distortion on hardening compared to oil-hardening grades, which makes it a preferred choice where tight finished tolerances must be held after heat treatment.

Key Features

• A2 air-hardening tool steel per AISI material specification for stable, low-distortion heat treatment
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal calculations
• Width tolerance of plus 0.000 to plus 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Squareness: edge 0.003 inches and ends 0.004 inches per inch of thickness
• Square tolerance of plus or minus 0.003 inches for accurate layout and fit-up

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock suitable for tool-and-die, fixture-making, and precision machining applications where AISI A2 cold-work tool steel is specified.

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. Wear proper personal protective equipment when cutting or grinding. Heat treatment of A2 tool steel requires controlled furnace equipment and should follow the material manufacturer's hardening and tempering guidelines. Always de-burr and inspect dimensions after cutting to length before use in a tool or fixture application.
