Drill Rod Tool Steels 85999787 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999787 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require tight dimensional tolerances and predictable heat-treat performance. Measuring 0.5 inches thick, 1.75 inches wide, and 36 inches long, this flat stock ships ready for layout, machining, and hardening operations. A2 tool steel is an air-hardening grade known for its dimensional stability during heat treatment and good wear resistance, making it a reliable choice for dies, punches, gauges, and precision tooling components. The bar weighs 9.03 pounds and is held to a thickness tolerance of plus or minus 0.001 inches.

This flat stock is suited for job shops, tool-and-die operations, and maintenance departments that fabricate or repair tooling in-house. The 36-inch length provides enough material for multiple blanks depending on the finished part geometry. The A2 grade is appropriate for applications requiring moderate toughness alongside good wear resistance, and its air-hardening characteristic reduces the risk of warping that can occur with oil- or water-hardening grades. Licensed machinists and toolmakers typically select this stock for blanking dies, forming tools, and precision fixtures.

Key Features

• A2 air-hardening tool steel grade for dimensional stability during heat treatment
• Thickness tolerance of plus or minus 0.001 inches for tight fit-up in tooling applications
• Width tolerance of plus 0.000 to plus 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Single-piece minimum order quantity for low-volume and one-off tooling needs

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock suitable for general tooling, die making, and precision machining applications where AISI A2 material specification is required.

Installation Notes

Machining and heat treating of A2 tool steel should be performed by qualified toolmakers or machinists familiar with AISI A2 processing requirements. Always follow established shop safety practices when cutting, grinding, or handling tool steel stock. Heat treatment, including hardening and tempering, should be performed in controlled furnace environments per the material specification; consult published A2 heat-treat guidelines for soak times and temperatures. Personal protective equipment including eye protection and cut-resistant gloves is recommended when handling and machining this material.
