Drill Rod Tool Steels 81175283 Flat Stock 36x7/8x1/8 in

Product Description

The DRILL ROD TOOL STEELS 81175283 is an AISI/SAE Type 4142 alloy steel pre hardened flat stock bar measuring 36 inches long, 7/8 inch wide, and 1/8 inch thick. Type 4142 is a chromium-molybdenum alloy steel known for high tensile strength, toughness, and wear resistance in the pre hardened condition. This flat stock ships ready for machining, grinding, or fabrication without requiring additional heat treatment. It is suited for tool and die makers, machinists, maintenance technicians, and industrial fabricators who need a reliable, tight-tolerance steel bar for precision applications.

This flat stock is used in machine shops, maintenance repair operations, and industrial fabrication environments. Typical applications include fixture components, tooling plates, wear strips, guides, brackets, and general-purpose structural or mechanical parts where moderate hardness and dimensional consistency are required. The pre hardened state makes it a practical choice when hardening after machining is not practical or desired. At 1.11 pounds per piece, it is a manageable single-piece bar for bench or mill work.

Key Features

• Square tolerance of 0.003 inches for consistent flatness and squareness across the stock
• Nominal dimensions of 36 inches long x 7/8 inch wide x 1/8 inch thick
• Ships as a single piece, minimum order quantity of 1

Compatibility

Designed as a general-purpose flat stock bar for use in machine shop, tooling, and industrial fabrication applications where AISI/SAE Type 4142 alloy steel pre hardened material is specified.

Installation Notes

This material is intended for machining, grinding, or fabrication by qualified machinists or toolmakers using appropriate metalworking equipment. Pre hardened stock is harder than annealed steel and may require carbide tooling for machining operations. Follow standard shop safety procedures including eye protection and secure workholding when cutting or grinding. No heat treatment is required before use, but any welding or re-hardening should follow established procedures for 4142 alloy steel.
