Drill Rod Tool Steels 58064 O1 Flat Stock 3/8x2x18 in

Product Description

The DRILL ROD TOOL STEELS 58064 is an O1 oil-hardening tool steel flat bar cut to 3/8 inch thick, 2 inches wide, and 18 inches long. O1 is an AISI-standard oil-hardening tool steel widely used in toolmaking, die making, and precision machining applications where consistent dimensional tolerances and reliable hardening response are required. This flat stock ships at a weight of 3.82 pounds and holds thickness tolerances of +0.010 to +0.015 inches, making it suitable for applications demanding close dimensional control before heat treatment. Machinists, tool and die makers, and metalworking shops are the primary users of this material.

This flat stock is used in fabrication of punches, dies, cutting tools, gauges, jigs, and fixtures in job shops and production machine shops. The 18-inch length and 2-inch width make it practical for short-run tooling blanks where stock can be cut to net shape prior to hardening. It is suited to both manual and CNC machining operations before the oil-quench hardening cycle. Applications are typically industrial and commercial metalworking environments rather than residential trade work.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable hardening response in oil quench
• Thickness tolerance of +0.010 to +0.015 inches for consistent pre-machining stock allowance
• Width tolerance of +0.010 to +0.015 inches
• Length tolerance of +0.250 inches
• Squareness held to 0.003 inches per inch of thickness on edges and 0.004 inches per inch of width on ends
• Ready-to-machine flat bar format - no additional saw cutting required for standard tooling blanks

Compatibility

Designed as a general-purpose O1 tool steel flat stock blank suitable for tooling, die, gauge, and fixture fabrication wherever AISI Type O1 oil-hardening material is specified.

Installation Notes

Machining and heat treatment of tool steel flat stock is performed by qualified machinists and tool and die makers. Follow standard shop safety procedures when sawing, milling, or grinding O1 steel. Oil-quench hardening operations should be conducted in accordance with the material manufacturer's recommended austenitizing temperature and quench sequence. Always allow stock to reach ambient temperature before final inspection of dimensions.
