Drill Rod Tool Steels 810984 O1 Flat Stock 9/64x3x18 in

Product Description

The DRILL ROD TOOL STEELS 810984 is an O1 oil-hardening flat stock bar cut to 9/64 inches thick, 3 inches wide, and 18 inches long. Made from AISI Type O1 tool steel, this flat stock is suited for toolmaking, die work, jigs, fixtures, and precision machined components that require tight dimensional tolerances and a reliable oil-hardening response. It weighs approximately 2.18 pounds per piece and holds a thickness tolerance of plus or minus 0.001 inches, making it a practical choice where consistent stock dimensions are critical before heat treat and final grinding.

O1 oil-hardening tool steel flat stock is commonly used in machine shops, tool and die shops, and maintenance environments for fabricating punches, dies, blades, gauges, and general tooling. The 18-inch length suits bench-scale toolmaking as well as short-run production parts. This bar ships in annealed condition, ready for machining prior to oil-quench hardening. Licensed machinists, toolmakers, and maintenance technicians are the primary installers and users of this material.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable hardening response in oil quench
• Tight thickness tolerance of plus or minus 0.001 inches for consistent pre-grind stock removal
• 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 edge and 0.004 inches per inch of thickness on ends
• Supplied in annealed condition, ready for machining and subsequent heat treatment

Compatibility

Designed as a standard O1 oil-hardening tool steel flat bar for general toolmaking, die making, and precision machined component applications requiring AISI Type O1 material specification.

Installation Notes

Material should be machined in the annealed condition before oil-quench hardening. Operators should follow established shop safety practices when sawing, milling, or grinding tool steel, including proper machine guarding and coolant use. Heat treatment should be performed by qualified personnel following published O1 hardening and tempering procedures. Allow the bar to reach room temperature before measurement to avoid thermal expansion error.
