Drill Rod Tool Steels 03720109 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03720109 is an A2 air-hardening tool steel flat stock bar sized at 0.75 inches thick, 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 wear resistance. This flat stock is supplied to close tolerances and is intended for use by machinists, tool and die makers, and industrial fabricators who need a reliable, ready-to-machine blank for tooling, dies, punches, and fixture components. Weighing approximately 15.82 pounds per bar, it is sized for practical handling on most shop floors.

This flat stock is suited for cold-work tooling applications including dies, punches, forming tools, gauges, and precision fixture components. It is commonly used in tool rooms, job shops, and manufacturing facilities where controlled heat treatment and tight dimensional tolerances are required. The 36-inch length allows multiple blanks to be cut from a single bar, reducing material waste in production runs.

Key Features

• Width: 2 inches with tolerance of +0.010 to 0.015 inches
• Length: 36 inches with tolerance of +0.250 to 0.500 inches
• Square tolerance: +/- 0.003 inches for consistent cross-section geometry
• Ready-to-machine flat stock, no additional surface preparation required before layout

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for cold-work die and tooling applications where A2 material specification is required.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified machinists or tool and die makers familiar with cold-work die steels. Always follow established shop safety procedures when cutting, grinding, or heat treating tool steel. Heat treatment should be performed according to A2 material specifications using controlled atmosphere or vacuum furnaces to minimize decarburization. Allow proper soak and quench cycles as specified for A2 grade before any secondary machining or grinding operations.
