Drill Rod Tool Steels 57785 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57785 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 7/16 inches thick, 6 inches wide, and 18 inches long, with a weight of 13.53 pounds. O1 is a general-purpose oil-hardening tool steel known for good dimensional stability during heat treatment, making it a standard choice for jigs, fixtures, gauges, punches, and cutting tools. This material is supplied in the annealed condition and is intended for further processing by machinists and toolmakers.

This flat stock is used in job shops, tool and die facilities, and maintenance departments where precision stock material is required. Its combination of machinability in the annealed state and consistent hardening response makes it suitable for short-run tooling, blanks, and wear components. Sold in single-piece quantity, this bar is appropriate for both individual project work and as part of a larger material order by trade professionals requiring reliable O1 flat stock in this specific size.

Installation Notes

Machining and heat treatment of O1 tool steel flat stock should be performed by qualified machinists or toolmakers familiar with oil-hardening steel procedures. Always follow established shop safety protocols when cutting, grinding, or heat treating tool steel. Hardening and tempering operations require controlled furnace temperatures and a proper quench medium - consult the material manufacturer or a qualified metallurgist for heat treatment parameters. Use appropriate personal protective equipment when handling and processing this material.
