Drill Rod Tool Steels 57844 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57844 is an O1 oil-hardening tool steel flat stock bar measuring 1 inch thick, 8 inches wide, and 18 inches long. O1 tool steel is a general-purpose oil-hardening grade valued for its dimensional stability during heat treatment and its ability to hold a keen edge after hardening. This flat stock is supplied in the annealed condition, ready for machining before hardening. Machinists, toolmakers, and die makers rely on this grade for punches, dies, gauges, and cutting tools where tight dimensional tolerances and consistent material quality are required.

This flat stock is suited for job shop, toolroom, and production environments where O1 is the specified material. Typical applications include blanking dies, forming dies, cutting blades, woodworking tools, and precision gauges. The 1 inch thickness and 8 inch width make this bar appropriate for larger tooling components that require a substantial cross-section before machining. It is commonly stocked by tool and die shops and metal service centers for short-run fabrication.

Key Features

• AISI Type O1 oil-hardening tool steel - stable during heat treat with good wear resistance
• Tight thickness tolerance of plus or minus 0.001 inches for consistent stock removal planning
• Width tolerance of plus 0.005 inches, minus 0.000 inches for predictable fit in fixtures
• Length tolerance of plus 0.25 inches - allows for facing or squaring to final length
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Annealed condition supports machining prior to hardening and tempering

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat bar for use in toolroom and die-making applications where O1 material specification is required.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate carbide or high-speed steel tooling. Heat treatment - including hardening and tempering - should follow established procedures for AISI O1 and be performed in a controlled atmosphere or with appropriate anti-scale measures to maintain surface integrity. Always wear appropriate personal protective equipment when cutting, grinding, or heat treating tool steel. Verify final dimensions after any heat treatment cycle before committing stock to finish grinding.
