Drill Rod Tool Steels 812618 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 812618 is an O1 oil-hardening tool steel flat bar used in toolmaking, jig building, die work, and precision machining applications. Conforming to AISI Type O1 specification, this flat stock measures 9/32 inches thick, 1-1/2 inches wide, and 36 inches long, with a weight of 4.36 pounds. O1 tool steel offers good machinability in the annealed state and responds predictably to oil-quench hardening, making it a standard choice for punches, dies, gauges, and cutting tools where dimensional stability after heat treatment is required. Machinists, toolmakers, and die makers are the primary users of this material.

This flat stock is suited for both job shop and production toolroom environments. The 36-inch length allows for multiple blanks to be cut from a single piece, reducing waste in short-run tooling operations. The 9/32-inch thickness and 1-1/2-inch width are common sizing for small punch blanks, wear plates, and flat die components. This material is supplied in the annealed condition and must be hardened and tempered by the end user to achieve working hardness.

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat bar suitable for toolroom fabrication of punches, dies, gauges, blades, and other precision tooling components requiring a standard AISI O1 material specification.

Installation Notes

Machining should be completed prior to heat treatment, as hardened O1 steel requires grinding for final dimensioning. Oil-quench hardening and tempering should be performed by a qualified heat treater or experienced toolmaker following recognized metallurgical procedures for AISI O1. Use appropriate personal protective equipment when cutting, grinding, or heat treating tool steel. Follow applicable shop safety codes when operating cutting or grinding equipment.
