Drill Rod Tool Steels 57932 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57932 is an O1 oil-hardening tool steel flat stock designed for precision toolmaking, die work, jigs, fixtures, and general machining applications where consistent dimensional tolerances are critical. Conforming to AISI Type O1 specification, this flat stock measures 3/8 inch thick, 3 inches wide, and 36 inches long, weighing 11.6 pounds. O1 tool steel offers excellent machinability in the annealed state and responds well to oil-quench hardening, making it a standard choice for toolmakers and machinists who need predictable heat-treat response without the complexity of water-hardening grades.

This flat stock is suited for machine shops, tool and die operations, and industrial fabrication environments. It is commonly used to produce punches, dies, gauges, knives, and similar precision tools. The 36-inch length provides enough stock for multiple parts to be cut from a single piece, reducing waste in high-turnover shop environments. Machinists working in both job-shop and production settings will find this a reliable, in-spec bar for demanding applications.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable heat-treat response
• Tight thickness tolerance of plus or minus 0.001 inches for consistent stock removal
• Width tolerance of plus 0.005 inches, minus 0.000 inches for reliable fit-up
• Length tolerance of plus 0.5 inches ensures full usable length
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• 36-inch length suitable for cutting multiple blanks from a single piece

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat bar for general toolmaking, die making, and precision machining applications requiring oil-quench heat treatment.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate metal-cutting equipment and coolant. All heat-treating operations, including oil quenching and tempering, should follow established metallurgical procedures for AISI O1 and be performed by qualified personnel. Wear appropriate PPE including eye protection and heat-resistant gloves when handling and processing tool steel stock. Secure workpieces properly before cutting to prevent movement and ensure accurate dimensions.
