Drill Rod Tool Steels 85997674 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85997674 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, die makers, and machine shops requiring close-tolerance steel stock. This flat bar measures 0.5 inches thick, 2 inches wide, and 72 inches long, and weighs 20.64 pounds. A2 tool steel is an air-hardening, cold-work die steel known for good dimensional stability during heat treatment, moderate wear resistance, and toughness. This stock is supplied in the annealed condition, ready for machining, grinding, and subsequent hardening by a qualified tool room technician or heat treater.

This flat stock is suited to fabrication of punches, dies, forming tools, gauges, and fixtures in both job-shop and production tool room environments. The 72-inch bar length allows multiple blanks to be cut from a single piece, reducing material waste. Thickness is held to a tolerance of plus or minus 0.001 inches, width to plus 0.000 to 0.005 inches, and length to plus or minus 1 inch, making it appropriate for precision tooling applications where consistent stock dimensions are required before finish grinding.

Key Features

• AISI A2 air-hardening tool steel composition for stable heat treatment and good toughness
• Tight thickness tolerance of plus or minus 0.001 inches for precision tool room use
• Width tolerance of plus 0.000 to 0.005 inches for consistent stock sizing
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• 72-inch length provides flexibility for cutting multiple blanks per bar
• Supplied annealed for ease of machining prior to hardening

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for use in general tool room, die making, and fixture fabrication applications requiring cold-work tool steel material.

Installation Notes

This material is handled and processed by machinists, toolmakers, and die makers using conventional metal cutting and grinding equipment. Follow established shop practices for cutting, sawing, and grinding tool steel bar stock. Heat treatment, including hardening and tempering of A2 tool steel, must be performed by a qualified heat treater following the material specification requirements. Always use appropriate personal protective equipment when cutting or machining steel stock.
