Drill Rod Tool Steels 85999340 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999340 is an A2 air-hardening tool steel flat stock bar measuring 3/32 inches thick, 5 inches wide, and 36 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its good dimensional stability during heat treatment, moderate toughness, and wear resistance. This flat stock is used by toolmakers, machinists, and die makers to fabricate punches, dies, gauges, forming tools, and other precision tooling components. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where close dimensional control before and after hardening is required.

This flat stock is suited for cold-work tooling applications in machine shops, tool and die operations, and maintenance departments. Typical uses include blanking dies, forming dies, trimming tools, and precision gauges where dimensional stability during air hardening is a priority. The 36-inch length and 5-inch width provide sufficient material for multiple tooling blanks from a single piece. No specific compatible equipment models are listed in the product data.

Key Features

• A2 air-hardening tool steel offers good dimensional stability during heat treatment compared to oil-hardening grades
• Tight thickness tolerance of plus or minus 0.001 inches supports precision layout and machining work
• Width tolerance held to plus 0.000 to plus 0.005 inches for consistent stock sizing
• Length tolerance of plus or minus 0.250 to 0.500 inches is standard for flat stock bar
• Squareness tolerance of 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• AISI Type A2 material specification for traceability in toolmaking and die-making applications

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for cold-work tooling fabrication in machine shop and tool and die environments.

Installation Notes

A2 tool steel flat stock is typically cut, ground, and machined by toolmakers or machinists before hardening. Rough machine the part to near-final dimensions before heat treatment, leaving stock for finish grinding after hardening. Air-hardening steel requires controlled atmosphere or vacuum heat treatment to minimize decarburization; follow the material supplier or heat treater guidelines for proper austenitizing and tempering temperatures. Always wear appropriate PPE when cutting or grinding tool steel.
