Drill Rod Tool Steels 81174732 Alloy Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 81174732 is an AISI/SAE Type 4142 alloy steel pre hardened flat stock bar measuring 18 inches long, 1 inch wide, and 5/8 inch thick. This material is supplied in a pre hardened condition, making it ready for applications that demand higher strength and wear resistance than standard mild steel. It is used by machinists, tool and die makers, fabricators, and maintenance technicians who need a reliable, dimensionally consistent steel flat for cutting, machining, or custom fabrication work. The bar ships at 3.17 pounds, offering a manageable size for bench and machine work alike.

This flat stock is well suited for tooling fixtures, jigs, wear plates, machine components, and general maintenance applications in industrial and manufacturing environments. The pre hardened 4142 alloy grade provides good toughness and machinability in the hardened state, making it a practical choice where through-hardened material is needed without additional heat treatment. It is typically stocked and used in machine shops, maintenance repair operations, and fabrication facilities.

Installation Notes

Cutting and machining of pre hardened 4142 alloy steel requires carbide tooling and appropriate speeds and feeds for hardened material. Always wear appropriate personal protective equipment when cutting, grinding, or machining steel stock. Follow your facility safety plan and applicable OSHA guidelines when handling and processing steel bar stock. Deburr all cut edges before use in fixtures or assemblies.
