Drill Rod Tool Steels 57795 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57795 is an O1 oil-hardening tool steel flat stock bar conforming to AISI Type O1 material specification. This piece measures 0.5 inches thick, 14 inches wide, and 18 inches long, and weighs 35.7 pounds. O1 tool steel is a general-purpose oil-hardening grade known for consistent dimensional stability and good machinability in the annealed state. It is used across toolmaking, die making, and precision machining applications where tight tolerances and predictable heat-treat response are required. Machinists and tool-and-die makers are the primary installers and fabricators working with this material.

This flat stock is suited for fabricating punches, dies, gauges, jigs, fixtures, and cutting tools in job shops, tool rooms, and precision manufacturing environments. The 14-inch width and 18-inch length provide substantial stock for layout and profiling operations. The annealed condition allows for machining, grinding, and EDM operations prior to heat treatment. Stock of this size is typically sourced for medium to large tooling projects where a full-thickness section is needed before rough or finish machining.

• Length tolerance of plus 0.25 inches
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Ready for machining, grinding, or EDM in annealed condition prior to hardening

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat stock suitable for toolmaking, die making, and precision fixture fabrication applications requiring AISI Type O1 material.

Installation Notes

Cutting, machining, and grinding of tool steel flat stock should be performed by qualified machinists or tool-and-die makers using appropriate tooling rated for hardened or semi-hard steel. Always secure the workpiece properly before any cutting or grinding operation. Oil hardening requires controlled quench procedures following applicable heat-treatment guidelines for O1 tool steel. Inspect dimensions against print tolerances before beginning rough machining to account for the stated length and width tolerances.
