Drill Rod Tool Steels 57805 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57805 is an O1 oil-hardening tool steel flat stock bar cut to 5/8 inch thick, 1-1/2 inches wide, and 18 inches long. O1 is a general-purpose tool steel valued for its consistent oil-hardening response, good dimensional stability during heat treatment, and ease of machining in the annealed state. This flat stock is used to fabricate dies, punches, gauges, jigs, fixtures, and cutting tools. Machinists, toolmakers, and die makers work with this material in job shops, toolrooms, and production environments where tight-tolerance stock is required.

O1 tool steel flat stock in this size is a standard starting blank for hand tools, stamping dies, form tools, and wear components. The 18-inch length allows multiple shorter blanks to be cut from a single piece, reducing material waste on typical toolroom jobs. The 5/8 inch thickness is a common profile for medium-duty die plates and punch blanks. The material ships in the annealed condition, ready for machining before heat treatment.

Key Features

• AISI Type O1 oil-hardening tool steel, annealed condition for machinability

• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.250 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Weight of 4.84 pounds per piece

Compatibility

Designed as a standard O1 oil-hardening tool steel flat stock blank suitable for toolroom fabrication of dies, punches, gauges, and related components where oil-hardening tool steel is specified.

Installation Notes

Machining and heat treatment of O1 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling. Always follow established shop safety practices when cutting, grinding, or heat-treating tool steel stock. Oil hardening requires controlled quenching in the appropriate quench medium - consult the material data sheet for proper hardening and tempering temperatures before processing. Wear appropriate PPE when machining or handling sharp-edged stock.
