Drill Rod Tool Steels 811014 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 811014 is an O1 oil-hardening tool steel flat stock bar designed for precision toolmaking, jig and fixture fabrication, and die work. Conforming to AISI Type O1 specification, this flat stock measures 9/64 inches thick by 1/2 inches wide by 36 inches long and weighs 0.73 pounds. Thickness tolerance is held to plus or minus 0.001 inches, width tolerance is plus 0.005 inches and minus 0.000 inches, and length tolerance is plus 0.5 inches. These tight tolerances make it suitable for applications where dimensional accuracy is critical before heat treatment. Machinists, tool and die makers, and metalworking shops are the primary users of this stock.

O1 tool steel flat stock at this size is commonly used in the fabrication of cutting tools, punches, dies, gauges, and small machine parts. The 9/64 by 1/2 inch cross-section is well suited to thin blade-style tooling blanks and flat wear parts. This bar is supplied in the annealed condition, ready for machining to final geometry before oil-quench hardening. It is appropriate for both light production tooling and prototype work in machine shops, tool rooms, and metal fabrication environments.

Key Features

• AISI Type O1 oil-hardening tool steel - responds to oil quench for hardening after machining
• Thickness held to plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.005 inches and minus 0.000 inches supports reliable stock removal to final dimension
• Edge squareness tolerance of 0.003 inches per inch of thickness; end squareness 0.004 inches per inch of thickness
• 36-inch bar length with a plus 0.5-inch length tolerance provides full usable stock
• 0.73 pounds per bar - manageable for bench and manual machining operations

Compatibility

Designed as a general-purpose O1 tool steel flat bar for use in standard tool room and metalworking applications requiring oil-hardening material at a 9/64 x 1/2 inch cross-section.

Installation Notes

Machining and heat treatment of tool steel stock should be performed by qualified machinists or tool and die makers familiar with O1 steel properties. Wear appropriate personal protective equipment when cutting, grinding, or hardening. Oil-quench heat treatment should follow the steel supplier's recommended austenitizing temperature range and quench procedure. Consult applicable shop safety standards before beginning any heat treatment operation.
