Drill Rod Tool Steels 85998375 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85998375 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require tight-tolerance, ready-to-machine steel in a standard flat profile. Measuring 0.5 inches thick, 3.5 inches wide, and 18 inches long, this piece ships at approximately 9.02 pounds. A2 tool steel offers good dimensional stability during air hardening, moderate wear resistance, and high toughness - making it a common choice for dies, punches, forming tools, and gauges. The thickness tolerance is held to plus or minus 0.001 inches, supporting precision layout work straight from stock.

This flat stock is suited for job shops, tool-and-die operations, and maintenance departments that fabricate or repair cutting tools, blanking dies, and stamping components. The 18-inch length allows multiple blanks to be cut from a single piece with minimal waste. The ground flat stock profile reduces setup time when squareness and flatness are critical to the finished tool geometry.

Key Features

• AISI A2 air-hardening tool steel - stable dimensions through heat treat cycle

• Ships as a single piece - no minimum order beyond one unit

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock for use in general tool-and-die, stamping, and precision machining applications where AISI A2 material specification is required.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by a qualified machinist or toolmaker familiar with A2 steel processing requirements. Air hardening must be performed in a controlled atmosphere or with appropriate anti-scale compound to prevent surface decarburization. Always allow the workpiece to reach ambient temperature before taking final measurements. Follow applicable shop safety standards when cutting or grinding hardened steel.
