Drill Rod Tool Steels 85999654 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999654 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, die makers, machinists, and fabricators who require tight-tolerance steel stock for cutting tools, punches, dies, and similar precision components. Measuring 0.25 inches thick by 0.375 inches wide by 36 inches long and weighing 0.97 pounds, this bar is produced to AISI A2 specifications with a thickness tolerance of plus or minus 0.001 inches. A2 tool steel offers excellent dimensional stability during air hardening, making it a preferred choice where distortion control matters.

This flat stock is suited for machine shops, tool and die operations, and maintenance departments that need ready-to-use bar stock for fabricating precision tooling. The 36-inch length provides enough material to cut multiple blanks for punches, form tools, or gauge blocks. It is appropriate for both low-volume prototype work and higher-volume tool room production. The tight width and thickness tolerances reduce the amount of grinding required before heat treat.

Key Features

• AISI A2 air-hardening tool steel for low-distortion heat treatment
• Thickness tolerance of plus or minus 0.001 inches for precision fitment
• 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
• Single 36-inch bar per package, no minimum order beyond one piece

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for general tool and die applications requiring tight dimensional tolerances.

Installation Notes

Cutting, grinding, and heat treating of tool steel should be performed by qualified machinists or toolmakers familiar with A2 tool steel procedures. Always use appropriate personal protective equipment when cutting or grinding. Heat treating should follow established AISI A2 austenitizing and air-quench procedures; consult the material manufacturer for full heat treat parameters. Secure workpieces properly during machining to maintain the close tolerances this stock is supplied to.
