Drill Rod Tool Steels 816244 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 816244 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and fabricators who need a precision-ground blank ready for heat treatment and finishing. Conforming to AISI Type O1 material specification, this flat stock measures 0.25 inches thick, 6 inches wide, and 18 inches long. Thickness tolerance runs from +0.0100 to +0.0150 inches, width tolerance from +0.0100 to +0.0150 inches, and length tolerance is +0.2500 inches. Squareness on the edge is held to 0.003 inches per inch of thickness, and 0.004 inches per inch of width on the ends. At 7.65 pounds, this is a substantial blank suitable for producing dies, punches, gauges, and tooling fixtures.

O1 tool steel flat stock is commonly used in job shops, tool and die operations, and maintenance machining environments. This bar is sized for applications requiring a wide, thin plate form factor - useful for flat dies, stripper plates, wear plates, and similar tooling components. It ships in the annealed condition, ready for machining, then oil quench hardening to achieve working hardness. Installers and machinists working with this stock should plan for heat treatment by a qualified heat treater or in-house furnace operation per AISI O1 recommendations.

Key Features

• AISI Type O1 oil-hardening tool steel - machines well in annealed state and achieves high hardness after oil quench

• Tight thickness tolerance of +0.0100 to +0.0150 inches for consistent stock removal during machining
• Squareness held to 0.003 inches per inch of thickness on edges and 0.004 inches per inch of width on ends
• Ships as a single piece at 7.65 pounds - no cutting charge or minimum footage required

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for general toolmaking, die making, and precision machining applications where O1 grade material is specified.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified machinists and heat treaters familiar with AISI O1 procedures. Always machine in the annealed condition before hardening. Use appropriate personal protective equipment when cutting, grinding, or handling tool steel stock. Follow established shop safety practices and applicable OSHA standards when operating machine tools or heat treatment equipment.
