Drill Rod Tool Steels 06312128 A2 Flat Stock 3/16x1-1/4x18in

Product Description

The DRILL ROD TOOL STEELS 06312128 is an A2 air-hardening tool steel flat stock bar cut to 3/16 inch thick, 1-1/4 inches wide, and 18 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 in the annealed condition, ready for machining, grinding, and heat treating to finished tooling dimensions. Machinists, tool and die makers, and industrial maintenance technicians use this material to fabricate punches, dies, fixtures, blades, and precision tooling components where tight tolerances and predictable hardening response are required. The piece weighs approximately 1.73 pounds.

This flat stock is suited for tool rooms, job shops, and maintenance departments working on cold-work tooling applications. Typical uses include blanking dies, forming dies, shear blades, and gauges where moderate toughness combined with good wear resistance is needed. The 18-inch length provides sufficient stock for most single-part or short-run tooling jobs without requiring additional cutting from longer bar stock.

Key Features

• AISI A2 air-hardening tool steel for dimensional stability during heat treat
• Thickness tolerance of plus 0.010 to 0.015 inches for consistent fit in close-tolerance applications
• Width tolerance of plus 0.010 to 0.015 inches
• Length tolerance of plus 0.062 inches
• Square tolerance of plus or minus 0.003 inches
• Supplied annealed and ready for machining prior to hardening

Compatibility

Designed as a standard A2 air-hardening tool steel flat bar suitable for cold-work tooling, die making, and precision fixture fabrication applications requiring AISI A2 material specification.

Installation Notes

Machining and grinding should be completed in the annealed condition before heat treatment. A2 tool steel is air-hardened and requires controlled atmosphere or vacuum furnace hardening followed by immediate double tempering to relieve stress. All heat treating operations should be performed by a qualified heat treater familiar with AISI A2 procedures. Handle ground and hardened pieces carefully to avoid chipping edges prior to final grinding.
