Drill Rod Tool Steels 85999316 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999316 is an A2 air-hardening tool steel flat stock bar measuring 3/32 inches thick, 2-1/2 inches wide, and 36 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good balance of hardness and toughness. This flat stock is precision-ground to tight tolerances, making it suitable for fabricating punches, dies, gauges, fixtures, and other tooling components. Machinists, tool-and-die makers, and industrial fabricators work with this material to produce custom tooling from bar stock.

This flat stock is used in tool-and-die shops, maintenance departments, and machine shops where cold-work tooling must hold close dimensional tolerances after hardening. Its air-hardening characteristic reduces distortion compared to oil- or water-hardening grades, making it a practical choice for thin or complex cross-section tooling. The 36-inch length provides ample stock for cutting multiple blanks from a single piece.

Key Features

• AISI A2 air-hardening tool steel for reduced distortion during heat treat
• Precision flat stock ground to plus or minus 0.001 inch thickness tolerance
• Width tolerance held to plus 0.000 to 0.005 inch for consistent fit in fixtures
• Length tolerance of plus or minus 0.250 to 0.500 inch on 36-inch bar
• Squareness: edge 0.003 inch and ends 0.004 inch per inch of thickness
• Ready-to-machine bar stock for punches, dies, gauges, and tooling blanks

Compatibility

Designed as a general-purpose A2 air-hardening tool steel flat bar for cold-work tooling applications in tool-and-die, machining, and fabrication environments where AISI A2 material specification is required.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool-and-die makers using appropriate coolant to prevent edge burning. Heat treatment to full hardness should follow AISI A2 recommended austenitizing and air-quench procedures; consult your heat treating facility for specific cycles. Always wear appropriate PPE when cutting or grinding hardened or semi-hardened tool steel. Deburr all edges before use in tooling assemblies.
