Drill Rod Tool Steels 85999878 A2 Flat Stock 5/8x3x36 in

Product Description

The DRILL ROD TOOL STEELS 85999878 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. AISI A2 tool steel offers excellent dimensional stability during heat treatment and strong wear resistance after hardening. This flat stock measures 5/8 inch thick, 3 inches wide, and 36 inches long, with a weight of 19.34 pounds per piece. The air-hardening characteristic of A2 reduces the risk of warping and cracking during the hardening process, making it a reliable choice for close-tolerance tooling components. Licensed machinists and tool-and-die makers are the primary users of this material.

This A2 flat stock is suited for fabrication of punches, dies, jigs, fixtures, gauges, and forming tools in both shop and industrial environments. Its tight thickness tolerance of plus or minus 0.001 inch and controlled width and length tolerances make it appropriate for precision work where dimensional consistency from the stock material matters before any secondary machining. It is typically stocked and cut to size for use in tool rooms and machine shops handling medium to high production tooling needs.

Key Features

• AISI A2 air-hardening tool steel for reduced distortion during heat treat
• Thickness tolerance of plus or minus 0.001 inch for consistent stock sizing
• Width tolerance of plus 0.000 to plus 0.005 inch
• Length tolerance of plus or minus 0.250 to 0.500 inch
• Squareness: edge 0.003 inch and ends 0.004 inch per inch of thickness
• Ready-to-machine flat stock requiring no initial straightening in most applications

Compatibility

Designed as a general-purpose A2 tool steel flat stock suitable for tool-and-die, punch, gauge, and fixture fabrication applications where AISI A2 air-hardening material is specified.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists using appropriate tooling rated for hardened or pre-hardened steel. Handle with care to avoid nicking precision-ground surfaces prior to secondary operations. Heat treatment should follow established AISI A2 hardening procedures and is typically performed by a certified heat treating facility. Always follow applicable shop safety standards when working with tool steel bar stock.
