Drill Rod Tool Steels 57836 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57836 is an O1 oil-hardening tool steel flat stock bar sized at 1 inch thick, 1-1/4 inches wide, and 18 inches long. AISI Type O1 is a general-purpose oil-hardening tool steel known for its machinability in the annealed state and its ability to achieve high hardness after heat treatment. This flat stock is used by tool and die makers, machinists, and metalworking shops for fabricating punches, dies, gauges, bushings, and similar tooling components. Tight dimensional tolerances make it suitable for precision applications where consistent stock dimensions matter before and after machining.

This flat bar stock is a standard choice for job shops, maintenance toolrooms, and manufacturing facilities that need reliable O1 tool steel in small quantities. It ships as a single piece at 18 inches long, making it practical for prototyping, short-run tooling, and replacement die components. Metalworking tradespeople and tool and die machinists are the primary installers and end users of this material.

• Single-piece quantity suitable for small-batch tooling and prototype work

Compatibility

Designed as a general-purpose O1 tool steel flat stock suitable for fabrication of punches, dies, gauges, and similar precision tooling components in standard metalworking and tool-and-die applications.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists using appropriate metalworking equipment. O1 tool steel is typically worked in the annealed condition prior to heat treatment. Heat treatment, including hardening and tempering, should follow established metallurgical procedures for AISI O1 and should be performed by personnel familiar with tool steel processing. Always wear appropriate personal protective equipment when cutting or grinding steel stock.
