Drill Rod Tool Steels 57771 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57771 is an O1 oil-hardening tool steel flat stock bar measuring 3/8 inch thick, 7 inches wide, and 18 inches long. O1 tool steel is a general-purpose, oil-quenched cold-work steel widely used in toolmaking, die-making, and precision machining applications where dimensional stability and good wear resistance after hardening are required. This flat stock ships in the annealed condition and is ready for machining, grinding, and heat treating. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for precision tool and die work where tight dimensional control is critical. Machinists, toolmakers, and die makers are the primary users of this material.

This flat stock is suited for fabricating punches, dies, gauges, blanking tools, knives, and similar toolroom components in both job shop and production environments. The 3/8 inch by 7 inch by 18 inch size is a practical off-the-shelf dimension for medium-format tooling blanks that require further machining or grinding to final size. This bar is appropriate for job shops, tool and die facilities, and maintenance departments requiring a reliable O1 flat stock in a standard size without committing to full-length bar stock.

Key Features

• AISI Type O1 oil-hardening tool steel for good wear resistance and dimensional stability after heat treatment
• Tight thickness tolerance of plus or minus 0.001 inches for precision toolroom applications
• Width tolerance of plus 0.005 inches, minus 0.000 inches for predictable material allowance
• Length tolerance of plus 0.25 inches for safe saw-cut oversize delivery
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Annealed condition allows straightforward machining and grinding before oil-quench hardening

Compatibility

Designed as a standard off-the-shelf O1 oil-hardening tool steel flat stock for use in general toolmaking, die-making, and precision machining applications requiring AISI Type O1 material specification.

Installation Notes

Cutting, grinding, and heat treating of tool steel should be performed by qualified machinists or toolmakers following established shop safety practices. Always power down and lock out any machine tool before securing the workpiece. Oil-hardening heat treatment requires a controlled furnace and an appropriate quench oil tank - follow the steel manufacturer's published heat treat data for O1 for austenitizing temperature and soak time. Wear appropriate PPE including heat-resistant gloves and face protection during quenching operations.
