Drill Rod Tool Steels 85998235 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85998235 is an A2 air-hardening tool steel flat stock bar used in tool and die making, fixture building, and precision machining applications. This piece measures 0.25 inches thick, 0.375 inches wide, and 18 inches long, with a shipping weight of 0.49 pounds. A2 tool steel offers good wear resistance and dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and other tooling components that require consistent hardness and tight tolerances after heat treatment. Machinists, toolmakers, and metalworking shops are the primary users of this stock material.

This flat stock is suited for both prototype and production tooling environments where precise blank dimensions are required prior to heat treating. The tight dimensional tolerances on thickness, width, and length allow for minimal stock removal during grinding and finishing operations. Typical applications include blanked die sections, form punches, cutting blades, and similar tool steel components fabricated in job shops or in-house maintenance departments.

Key Features

• AISI A2 air-hardening tool steel for consistent, low-distortion hardening
• Thickness tolerance of plus or minus 0.001 inches for precision fit-up
• Width tolerance of plus 0.000 to minus 0.005 inches for controlled sizing
• Length tolerance of plus or minus 0.062 inches
• Squareness: edge 0.003 inches and ends 0.004 inches per inch of thickness
• Ready-to-machine flat stock format - no additional profiling required before use

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat bar suitable for general tooling, die, and fixture fabrication applications across metalworking trades.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. Follow all shop safety protocols when sawing, grinding, or drilling this material. Heat treatment to achieve hardness should be performed by a qualified heat treater using documented A2 air-hardening procedures - do not attempt open-flame hardening without proper equipment and controls. Wear appropriate PPE including eye protection and cut-resistant gloves when handling sharp-edged stock.
