Drill Rod Tool Steels 03717766 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03717766 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die shops requiring close-tolerance stock for fabrication of punches, dies, gauges, and fixtures. Measuring 0.125 inches thick, 0.75 inches wide, and 36 inches long, this flat bar ships in an unfinished, unhardened condition ready for machining prior to heat treatment. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional consistency before hardening is critical. Weight is approximately 0.96 pounds per bar.

A2 air-hardening tool steel is a general-purpose cold-work grade well suited for cutting tools, forming dies, blanking tools, and precision fixtures in both job-shop and production environments. This flat stock is commonly machined to net shape or near-net shape, then air hardened in a controlled atmosphere furnace to minimize distortion. It is appropriate for applications demanding moderate wear resistance and good toughness in the hardened state.

Key Features

• Width tolerance: plus 0.000 to 0.005 inches
• Length tolerance: plus or minus 0.250 to 0.500 inches
• Square tolerance: plus or minus 0.003 inches
• Single-bar quantity available - MOQ of 1

Compatibility

Designed as a standard-format A2 tool steel flat stock bar suitable for use in toolmaking, die making, and precision machining applications requiring AISI A2 air-hardening grade material.

Installation Notes

Machining and heat treatment of tool steel flat stock should be performed by qualified toolmakers or machinists familiar with A2 air-hardening grades. The bar should be fully machined to final geometry before hardening. Air hardening must be performed in a controlled atmosphere or vacuum furnace to prevent decarburization of critical surfaces. Always allow the bar to reach room temperature uniformly before final measurement and inspection post-quench.
