Drill Rod Tool Steels 58032 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 58032 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require a reliable, machinable blank ahead of heat treatment. Conforming to AISI Type O1 specification, this flat stock measures 1.5 inches thick by 3.5 inches wide by 36 inches long and weighs 53.55 pounds. O1 tool steel offers excellent machinability in the annealed state and hardens predictably in an oil quench, making it a standard choice for punches, dies, gauges, jigs, and cutting tools fabricated in-shop.

This flat stock is suited for machine shops, tool-and-die operations, and industrial maintenance departments that produce or repair tooling components. The 36-inch length provides a full working bar that can be cut to multiple blanks on a bandsaw or cold saw. The combination of 1.5-inch thickness and 3.5-inch width covers a wide range of die block, punch holder, and fixture plate applications where stock removal is performed prior to hardening and tempering.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches for close-tolerance blanks
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Full 36-inch bar length suitable for multiple blanks per stick

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general tooling, die making, punch fabrication, and fixture applications requiring a stock blank that will be machined and heat treated to final size.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate metalworking equipment such as bandsaws, milling machines, and surface grinders. Heat treatment, including hardening and oil quenching, should follow established metallurgical procedures for AISI O1 and should be performed by personnel familiar with tool steel processing. Always wear appropriate PPE when cutting or grinding tool steel. Handle the 53.55-pound bar with proper lifting equipment or assistance to prevent injury.
