Drill Rod Tool Steels 466 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 466 is an A2 air-hardening tool steel flat stock cut to 5/8 inches thick, 5/8 inches wide, and 36 inches long. A2 tool steel is a chromium-molybdenum alloy known for its dimensional stability during air hardening and its balance of toughness and wear resistance. This flat stock ships in annealed condition, ready for machining before heat treatment. It is used by tool and die makers, machinists, and metalworking professionals who need precision-tolerance stock for punches, dies, gauges, and cutting tools. The piece weighs approximately 3.98 pounds.

A2 flat stock in this 5/8 x 5/8 x 36-inch size is a standard blank for fabricating small-to-medium stamping dies, form blocks, and precision cutting tools. It is suited for both job shop and in-house toolroom applications where controlled air hardening minimizes distortion. The 36-inch length allows multiple blanks to be cut from a single piece, reducing material waste in short-run toolmaking operations.

Key Features

• A2 air-hardening tool steel for minimal distortion during heat treatment
• Tight thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Square tolerance of plus or minus 0.003 inches
• Ships in annealed condition, machinable before hardening

Compatibility

Designed as a standard A2 air-hardening tool steel flat bar for general toolroom and die shop use where AISI A2 material specification is required.

Installation Notes

Cutting and grinding should be performed before heat treatment. Air hardening requires proper soak temperature and controlled cooling per AISI A2 guidelines - consult a certified heat treater or published A2 heat treat data for time and temperature parameters. Use appropriate personal protective equipment and coolant when machining. Finished tooling should be inspected dimensionally after hardening to confirm tolerance compliance.
