Drill Rod Tool Steels 85999746 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999746 is an A2 air-hardening tool steel flat stock bar measuring 3/8 inch thick, 5 inches wide, and 36 inches long. A2 tool steel is a chromium-molybdenum alloy known for its dimensional stability during air hardening, good wear resistance, and moderate toughness. This flat stock is supplied in the annealed condition and is used for fabricating dies, punches, jigs, fixtures, and precision tooling components. Machinists and tool-and-die makers work with this material to produce tooling that requires a reliable hardening response and tight dimensional control after heat treatment.

This flat stock is suited for tool rooms, machine shops, and die-making operations that require consistent stock dimensions prior to rough machining and hardening. The 36-inch bar length accommodates a wide range of tooling blanks. Thickness tolerance is held to plus or minus 0.001 inch, making it appropriate for applications where close pre-machine stock allowance matters. Width tolerance is held to plus 0.000 to 0.005 inch, and length tolerance is plus or minus 0.250 to 0.500 inch.

Key Features

• AISI A2 air-hardening tool steel - stable dimensions during heat treatment compared to oil-hardening grades
• Thickness tolerance of plus or minus 0.001 inch for tight pre-machining allowance
• Width tolerance of plus 0.000 to 0.005 inch
• Square tolerance of plus or minus 0.003 inch per side
• Squareness held to 0.003 inch on edges and 0.004 inch on ends per inch of thickness
• 36-inch bar length suitable for a range of tooling blank applications

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock for use in tool-and-die, punch, fixture, and precision tooling fabrication applications requiring AISI A2 material specification.

Installation Notes

Machining, grinding, and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling procedures. Always follow the material manufacturer's recommended annealing, hardening, and tempering cycles for A2 grade steel. Use appropriate personal protective equipment when cutting, grinding, or machining. Consult applicable shop safety standards before beginning any heat-treat operations.
