Drill Rod Tool Steels 03717840 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03717840 is an A2 air-hardening tool steel flat stock bar measuring 0.125 inches thick, 4 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 tool and die makers, machinists, and metalworking shops that require precision-ground stock for punches, dies, gauges, and similar tooling applications. At 5.1 pounds per piece, it is sized for bench work and CNC or manual machining operations.

This flat stock is suited for fabrication of cold-work tooling components in job shops, tool rooms, and maintenance departments. Typical applications include blanking dies, forming tools, trim dies, and precision gauges where moderate toughness and good wear life are required. The 36-inch length allows for multiple parts to be cut from a single bar, reducing material waste on production runs.

Key Features

• A2 air-hardening tool steel per AISI classification - good dimensional stability during heat treat
• Precision flat stock ground to tight thickness tolerance of plus or minus 0.001 inches
• Width tolerance of plus 0.000 to 0.005 inches for consistent fit in tooling setups
• Length tolerance of plus or minus 0.250 to 0.500 inches standard for bar stock
• Square tolerance of plus or minus 0.003 inches for accurate layout and machining
• 36-inch bar length supports multi-part yield in tool room applications

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for cold-work tooling, die making, and precision machining applications where A2 grade material is specified.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. A2 steel requires controlled heat treatment - austenitizing, air quenching, and tempering - performed in a calibrated furnace to achieve target hardness; do not attempt open-flame hardening. Always wear appropriate PPE including safety glasses and gloves when handling bar stock with sharp edges. Follow applicable shop safety codes when operating cutting or grinding equipment.
