Drill Rod Tool Steels 809362 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 809362 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, jig fabrication, and precision machining applications. Conforming to AISI Type O1 specification, this flat bar measures 3/64 inches thick, 6 inches wide, and 18 inches long, weighing 1.45 pounds. O1 tool steel is a manganese-chromium-tungsten alloy known for its dimensional stability during oil quench hardening, making it a standard material choice for blanking dies, punches, and fixture plates that require a hardened, wear-resistant surface.

This flat stock is suited for machine shops, tool-and-die operations, and fabrication environments where pre-cut O1 blanks reduce material prep time. The 6-inch width and 18-inch length provide a usable blank for moderate-sized tooling components without requiring initial shearing from larger stock. It ships at annealed hardness, ready for machining before the final oil-hardening heat treatment cycle.

Key Features

• AISI Type O1 oil-hardening tool steel for consistent response to heat treatment
• Dimensions: 3/64 inches thick x 6 inches wide x 18 inches long
• Thickness tolerance of +/- 0.001 inches for tight dimensional control
• Width tolerance of +0.005 / -0.000 inches
• Length tolerance of +0.250 inches
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• Annealed condition as supplied - machinable before hardening

Compatibility

Designed as a standard O1 oil-hardening tool steel flat blank compatible with general toolmaking, die making, and precision fixture applications requiring AISI Type O1 material specification.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified machinists or tool-and-die technicians familiar with O1 oil-hardening procedures. Material should be fully machined and finished to near-final dimensions before the hardening cycle, as post-hardening material removal is limited to grinding. Follow the steel manufacturer's recommended austenitizing temperature and quench media guidelines for O1 alloy. Always use appropriate PPE when handling hot steel and quench oil.
