Drill Rod Tool Steels 66794 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 66794 is an O1 oil-hardening tool steel flat stock bar conforming to AISI Type O1 material specification. It measures 1/16 inch thick, 2 inches wide, and 36 inches long, and weighs 1.29 pounds. O1 tool steel is a general-purpose oil-hardening grade valued for its dimensional stability during heat treatment, good machinability in the annealed state, and ability to hold a sharp edge after hardening. This flat stock is used by machinists, toolmakers, die makers, and metalworking professionals who need a precision-ground blank ready for layout, machining, and subsequent heat treatment.

O1 flat stock in this size range is commonly used in tool and die shops, maintenance departments, and machine shops for fabricating punches, dies, gauges, jigs, fixtures, blades, and cutting tools. The 2-inch width and 36-inch length make it well suited for medium-format tool blanks or can be cut to length for smaller components. It is appropriate for both one-off prototype tooling and short-run production of precision parts where tight dimensional tolerances are required prior to hardening.

Key Features

• AISI Type O1 oil-hardening tool steel construction for predictable heat treatment response
• Thickness tolerance of plus or minus 0.001 inches for tight dimensional control
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness tolerance of plus or minus 0.003 inches on edges; 0.004 inches per inch of thickness on ends
• Ships as a single 36-inch bar with no minimum order quantity beyond one piece

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 this material specification is required.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting fluids and tooling rated for tool steel. Eye protection and proper machine guarding are required during all cutting and grinding operations. Oil hardening heat treatment should be carried out in a controlled atmosphere or salt bath furnace by personnel familiar with O1 heat treatment procedures to avoid decarburization or distortion. Always allow the workpiece to reach ambient temperature before final inspection of dimensions.
