Drill Rod Tool Steels 57784 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57784 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, gauges, fixtures, and precision machined components requiring tight dimensional tolerances. Manufactured to AISI Type O1 specification, this flat stock measures 7/16 inches thick, 4 inches wide, and 18 inches long, and weighs 9.02 pounds. Thickness tolerance is held to plus or minus 0.001 inches, width tolerance is plus 0.005 minus 0.000 inches, and length tolerance is plus 0.25 inches. O1 tool steel responds well to oil quench hardening, making it a reliable choice where moderate toughness and good wear resistance are required after heat treatment.

This flat stock is suited for machine shops, toolrooms, and fabrication environments where precision stock is cut, ground, or machined into finished tooling. Typical applications include blanking dies, punches, forming tools, jigs, and wear plates. The 18-inch length allows multiple parts to be cut from a single piece in low-volume toolroom production. This material is intended for use by machinists, tool-and-die makers, and fabricators who require consistent pre-hardened or anneal-state stock that can be finish-machined and then hardened to specification.

Key Features

• AISI Type O1 oil-hardening tool steel - hardens by oil quench for good wear resistance and moderate toughness
• Thickness held to plus or minus 0.001 inches for tight fitment in precision tooling applications
• Width tolerance of plus 0.005 minus 0.000 inches and length tolerance of plus 0.25 inches
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Square tolerance of plus or minus 0.003 inches across flat surfaces
• Single-piece minimum order quantity - no bulk commitment required

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat stock suitable for toolroom and machine shop applications where AISI Type O1 material specification is required.

Installation Notes

Material should be cut, ground, or machined in the annealed state before heat treatment. Oil hardening requires controlled furnace heating and a proper oil quench - this work should be performed by a qualified heat treat technician or tool-and-die professional. Use appropriate personal protective equipment when cutting or grinding tool steel. Follow your facility safety plan and applicable OSHA guidelines when handling and machining steel stock.
