Drill Rod Tool Steels 57896 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57896 is an O1 oil-hardening tool steel flat bar cut to 3/16 inches thick, 3-1/2 inches wide, and 36 inches long. AISI Type O1 is a general-purpose oil-hardening tool steel valued for its dimensional stability during heat treatment, good machinability in the annealed state, and strong wear resistance after hardening. This flat stock is supplied in the annealed condition, ready for machining, grinding, or layout work before hardening. Toolmakers, die makers, and machine shop technicians are the primary users. At 6.77 pounds per piece, it is a practical single-piece order for prototyping or tool repair applications.

O1 flat stock in this size is commonly used in toolroom and job-shop environments for fabricating punches, dies, jigs, fixtures, gauges, and cutting tools. Its 3/16-inch thickness makes it well-suited for thin die plates, small fixture components, and blanking or forming tooling. This stock can be shaped and finished on conventional mills and surface grinders before oil quenching to achieve working hardness. It is appropriate for both low-volume production tooling and one-off repair work across manufacturing, metalworking, and industrial maintenance settings.

Key Features

• AISI Type O1 oil-hardening tool steel - stable dimensions during oil quench, suitable for precision tooling
• Annealed condition - machines and grinds cleanly before hardening
• Tight thickness tolerance of plus or minus 0.001 inches for consistent stock removal and fit-up
• Width tolerance of plus 0.005 to minus 0.000 inches maintains minimum material for final grinding
• Length tolerance of plus 0.5 inches ensures full usable length after facing
• Edge squareness held to 0.003 inches per inch of width; end squareness to 0.004 inches per inch of thickness

Compatibility

Designed as a standard AISI Type O1 oil-hardening flat stock suitable for general toolroom fabrication, die making, and fixture building applications where oil-quench heat treatment will be performed.

Installation Notes

Machining, grinding, and heat treatment of O1 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling. Always wear appropriate PPE when cutting, grinding, or handling sharp-edged flat stock. Heat treatment including oil quenching must follow established metallurgical procedures for AISI O1 and should be performed in a controlled environment with proper quench oil and fire safety measures in place. Do not attempt hardening operations without appropriate furnace equipment and quench setup.
