Drill Rod Tool Steels 58022 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 58022 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require a machinable, warp-resistant steel that responds predictably to oil-quench hardening. Measuring 1-1/4 inches thick, 2-1/2 inches wide, and 36 inches long, this flat stock ships at 32.24 pounds per piece. O1 tool steel is a manganese-chromium-tungsten alloy known for its excellent dimensional stability during heat treatment, making it a preferred choice for punches, dies, gauges, and cutting tools where tight finished tolerances are critical.

This flat stock is suited for machine shop and toolroom applications where stock must be rough-machined, hardened, and finish-ground to final dimensions. Typical uses include blanking dies, forming punches, jig components, and precision gauges. The 36-inch length provides enough material for multiple workpieces from a single bar, reducing handling and setup time in production toolroom environments.

Key Features

• AISI Type O1 oil-hardening tool steel construction for predictable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal in finish grinding
• Width tolerance of plus 0.005 to minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Single-piece minimum order quantity - no pallet minimums required

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat stock suitable for conventional toolroom machining, heat treating, and grinding operations wherever AISI Type O1 material specification is called out.

Installation Notes

Machining and heat treating of O1 tool steel should be performed by qualified toolmakers or machinists familiar with oil-quench hardening procedures. Always use appropriate personal protective equipment when cutting or grinding tool steel, and ensure heat-treating equipment is rated for the required austenitizing temperatures. Allow bars to reach ambient temperature before performing precision layout or measurement. Follow applicable shop safety codes and equipment manufacturer guidelines when operating surface grinders, milling machines, or heat-treat furnaces.
