Drill Rod Tool Steels 86216306 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 86216306 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require close-tolerance stock for fabricating punches, dies, jigs, and fixtures. This flat stock measures 0.25 inches thick by 3 inches wide by 18 inches long and weighs approximately 3.83 pounds. A2 tool steel is known for its balanced combination of wear resistance and toughness after air hardening, making it a reliable choice for medium-run tooling applications where dimensional stability during heat treatment is critical.

This flat stock is suited for machine shops, tool and die operations, and maintenance departments in industrial and manufacturing environments. The 18-inch length is a common drop size used for blank stock prior to milling, grinding, or EDM operations. Typical installers and users are toolmakers, CNC machinists, and die shop technicians working to close tolerances. The consistent cross-section and tight tolerance spec make it well-suited for parts requiring predictable stock removal during finish grinding.

Key Features

• AISI A2 air-hardening tool steel composition for dimensional stability during heat treat
• Thickness tolerance held to plus or minus 0.001 inches for consistent stock removal
• Width tolerance of plus 0.000 to minus 0.005 inches for tight fit-up on precision tooling
• Length tolerance of plus or minus 0.062 inches suitable for saw-cut blanks
• Square tolerance of plus or minus 0.003 inches for reliable setup and clamping
• Ready-to-machine flat stock format reduces setup time versus round or irregular bar

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for general toolmaking, die making, and fixture fabrication applications requiring air-hardening grade material.

Installation Notes

Machining and heat treating of tool steel should be performed by qualified toolmakers or machinists familiar with A2 steel handling procedures. Always follow established shop safety practices when sawing, milling, or grinding tool steel, including the use of appropriate PPE and coolant. Heat treatment of A2 steel requires controlled atmosphere or vacuum furnace conditions to achieve specified hardness; consult the material data sheet for austenitizing and tempering guidance. Secure workpieces properly before machining to prevent movement and maintain tolerance accuracy.
