Drill Rod Tool Steels 57874 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57874 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, jig fabrication, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 3/32 inches thick, 4 inches wide, and 36 inches long, and weighs 3.87 pounds. O1 tool steel offers excellent machinability in the annealed state and responds well to oil-quench hardening, making it a standard choice for punches, dies, gauges, and cutting tools. Machinists and toolmakers working in job shops or maintenance departments will find this bar sized for direct use with minimal material removal.

This flat stock is suited for general toolroom use in both job-shop and production environments. Typical applications include blanking dies, forming punches, drill bushings, gauges, and fixtures where dimensional stability after heat treatment is required. The 36-inch length allows single-piece blanking for most common toolroom components without a full bar saw-down. It is appropriate for shops holding AISI O1 as a standard stock material for on-demand toolmaking.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable response to oil-quench heat treatment
• Tight thickness tolerance of plus or minus 0.001 inches for consistent stock removal and fit-up
• Width tolerance of plus 0.005 inches to minus 0.000 inches maintains minimum material guarantee
• Length tolerance of plus 0.5 inches allows for facing and squaring without undersize risk
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• 36-inch bar length suits common toolroom blanking without full-bar handling

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock for toolroom, die shop, and precision machining applications requiring oil-quench hardenable material in a flat bar form.

Installation Notes

O1 tool steel flat stock is typically cut, ground, and machined by toolmakers or machinists using conventional metalworking equipment. All heat treatment - including annealing, hardening, and tempering - should be performed by qualified personnel following AISI O1 guidelines; never attempt hardening without proper furnace equipment and quench media. Wear appropriate PPE when sawing or grinding tool steel. Deburr all cut edges before handling or further machining.
