Drill Rod Tool Steels 57907 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57907 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require tight-tolerance stock material ready for machining and heat treatment. Conforming to AISI Type O1 specification, this flat bar measures 7/32 inches thick, 2 inches wide, and 36 inches long, weighing 4.46 pounds. O1 tool steel is a general-purpose oil-hardening grade known for its dimensional stability during heat treatment and its ability to hold a sharp, durable edge after hardening and tempering. This stock is suitable for fabricating punches, dies, gauges, and cutting tools.

This flat stock is used in machine shops, tool and die shops, and maintenance departments where precision blanks are needed for custom tooling. The 36-inch length provides sufficient material for multiple tool blanks from a single piece. Tight thickness tolerance of plus or minus 0.001 inches makes this bar suitable for applications where close dimensional control is required before finish grinding. It is typically purchased by tool and die makers, machinists, and industrial maintenance technicians.

Key Features

• AISI Type O1 oil-hardening tool steel - stable dimensionally through the hardening cycle
• Thickness tolerance of plus or minus 0.001 inches for close-tolerance machining
• Width tolerance of plus 0.005 inches / minus 0.000 inches

• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Ready-to-machine flat stock - no further surface prep required before layout and cutting

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general tool and die fabrication, gauges, punches, and similar applications requiring an oil-quench hardenable steel in flat bar form.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool and die makers familiar with O1 steel handling procedures. Always use appropriate coolant when grinding to avoid surface tempering. Heat treatment including hardening and tempering should follow recognized metallurgical procedures for AISI O1 tool steel. Wear appropriate PPE when cutting or machining tool steel stock.
