Drill Rod Tool Steels 03718525 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718525 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die shop professionals who require tight dimensional tolerances and predictable heat-treat performance. This bar measures 0.5 inches thick, 2.5 inches wide, and 36 inches long, weighing approximately 12.75 pounds. A2 tool steel is known for its excellent dimensional stability during air hardening, making it well suited for punches, dies, forming tools, and precision fixtures where minimal distortion after heat treatment is critical. Thickness tolerance is held to plus or minus 0.001 inches, and square tolerance is held to plus or minus 0.003 inches.

This flat stock is used in tool-and-die shops, machine shops, and industrial manufacturing environments for fabricating cutting tools, blanking dies, trim dies, gauges, and similar precision components. The 36-inch bar length provides a practical starting cut for a wide range of tooling applications. It is appropriate for both prototype and production tooling work where controlled heat treating and machinability are required before final hardening.

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for tooling, die-making, and precision machining applications that call for A2 grade material.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting fluids and carbide tooling. Heat treating should follow AISI A2 guidelines and is typically performed in a controlled atmosphere furnace to minimize scaling and decarburization. Always wear appropriate PPE when cutting or grinding tool steel. Follow applicable shop safety standards when handling stock of this weight and size.
