Drill Rod Tool Steels 57995 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57995 is an O1 oil-hardening tool steel flat stock bar intended for toolmaking, die making, jig and fixture fabrication, and precision machining applications. Manufactured to AISI Type O1 specification, this flat bar measures 7/8 inch thick, 1 inch wide, and 36 inches long, with a weight of 9.04 pounds. Tight dimensional tolerances make it well suited for applications where consistent stock sizing is required before heat treatment or final machining. Machinists, tool-and-die makers, and metalworking shops are the primary users of this material.

O1 tool steel flat stock is commonly used in the fabrication of cutting tools, punches, dies, gauges, and general-purpose tooling where oil-hardening capability and dimensional stability are required. This bar arrives in the annealed condition, allowing it to be machined to near-final dimensions before oil quench hardening. It is appropriate for both short-run production tooling and one-off precision components in job shop and in-house tool room environments.

Key Features

• AISI Type O1 oil-hardening tool steel material specification
• Thickness tolerance of plus or minus 0.001 inches for consistent stock sizing
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• Ready for machining in annealed condition prior to heat treatment

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat bar suitable for general toolmaking, die making, and precision machining applications requiring oil-quench heat treatment.

Installation Notes

This material is typically machined by experienced machinists or tool-and-die makers using conventional cutting tools appropriate for annealed tool steel. Allow adequate stock for grinding after heat treatment, as oil-hardening steels may experience minor dimensional change during quench. Heat treatment should be performed by qualified personnel following established procedures for AISI O1 tool steel. Handle bar stock carefully to avoid surface nicks or burrs that can affect final tolerance.
