Drill Rod Tool Steels 86210408 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 86210408 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. It measures 5/32 inches thick, 4 inches wide, and 18 inches long, with a thickness tolerance of plus or minus 0.001 inches for consistent fitment in close-tolerance setups. At 3.19 pounds, the bar ships as a single piece and is ready for annealed-state machining before hardening. A2 tool steel is known for its balanced wear resistance, toughness, and dimensional stability through the air-hardening process, making it a reliable choice for punches, dies, gauges, and cutting tools.

This flat stock is suited for job shops, tool and die makers, and maintenance machinists who need a predictable, machinable blank ahead of heat treatment. The 18-inch length provides enough material for most short-run tooling blanks or can be cut down to yield multiple smaller components. The 4-inch width supports wider die sections or plate-style tooling without the need for edge welding or joining.

Key Features

• A2 air-hardening tool steel for dimensional stability and reduced distortion during heat treat
• Thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.000 to minus 0.005 inches for controlled sizing
• Length tolerance of plus or minus 0.062 inches
• Square tolerance of plus or minus 0.003 inches
• Supplied in annealed condition for ease of machining prior to hardening

Compatibility

Designed as a standard A2 tool steel flat stock blank suitable for toolmaking, die fabrication, and general precision machining applications requiring air-hardening material.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified tool and die makers or machinists familiar with A2 steel requirements. Follow the material manufacturer's recommended annealing, hardening, and tempering temperature ranges for A2 tool steel. Proper personal protective equipment is required when cutting, grinding, or heat treating. Consult applicable shop safety standards and equipment guidelines before processing.
