Drill Rod Tool Steels 85999662 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999662 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, die makers, and machinists who need a dimensionally accurate, ready-to-machine blank. AISI A2 is an air-hardening, medium-alloy cold-work tool steel known for good dimensional stability during heat treatment and solid wear resistance. This piece measures 0.25 inches thick by 3.5 inches wide by 36 inches long and weighs 9.02 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where close stock dimensions reduce secondary grinding time before hardening.

This flat stock is used in fabrication of punches, dies, blanking tools, forming tools, and general cold-work tooling in job shops and manufacturing facilities. The 36-inch length allows multiple blanks to be cut from a single piece. Air-hardening characteristics reduce distortion risk during the hardening cycle compared to oil- or water-hardening grades, which is why A2 is a common choice for flat tooling and gauges where dimensional control after heat treat is critical.

Key Features

• AISI A2 air-hardening tool steel for reduced distortion during heat treatment
• Thickness held to plus or minus 0.001 inches for close-tolerance machining stock
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Squareness: edge 0.003 inches and ends 0.004 inches per inch of thickness
• Single-piece minimum order quantity suits low-volume toolroom procurement

Compatibility

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

Installation Notes

Cutting and machining should be performed by qualified toolmakers using appropriate metalworking equipment. Heat treatment to harden A2 tool steel must be carried out by a qualified heat treater following the material manufacturer's recommended austenitizing and tempering temperatures. Always allow the material to reach ambient temperature before precision measurement. Follow applicable shop safety procedures when cutting, grinding, or handling tool steel stock.
