Drill Rod Tool Steels 85999894 A2 Flat Stock 5/8x5x36 in

Product Description

The DRILL ROD TOOL STEELS 85999894 is a precision-ground A2 air-hardening tool steel flat stock bar used in toolmaking, die-making, and precision machining applications. Measuring 0.625 inches thick, 5 inches wide, and 36 inches long, this flat stock is manufactured to tight dimensional tolerances, including plus or minus 0.001 inches on thickness. A2 tool steel is known for its excellent dimensional stability during heat treatment and good wear resistance after air hardening, making it a reliable choice for punches, dies, gauges, and fixture components. This piece weighs approximately 32.22 pounds and conforms to AISI A2 material specification.

This flat stock is suited for machine shops, tool-and-die operations, and precision fabrication environments where controlled heat treatment and tight tolerances are required. A2 grade material is commonly selected for applications that demand moderate toughness combined with good wear resistance. The 36-inch length and 5-inch width provide stock that can be sawn, milled, or ground to final dimensions before hardening. Machinists and toolmakers working in both job-shop and production-shop settings regularly work with this stock format.

Key Features

• AISI A2 air-hardening tool steel for dimensional stability during heat treat
• Thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Squareness tolerance of 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Ready-to-machine flat stock format at 0.625 x 5 x 36 inches

Compatibility

Designed as a standard-format A2 tool steel flat stock suitable for toolmaking, die-making, punch fabrication, and precision fixture applications requiring air-hardening material.

Installation Notes

Machining and grinding of A2 tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate cutting fluids and carbide or high-speed steel tooling. Heat treatment, including hardening and tempering, should follow recognized metallurgical guidelines for AISI A2 and be performed by a qualified heat-treating professional or facility. Always allow the material to reach ambient temperature before precision grinding to final tolerances. Appropriate eye and hand protection should be worn during all cutting, grinding, and handling operations.
