Drill Rod Tool Steels 57750 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57750 is an O1 oil-hardening tool steel flat stock bar conforming to AISI Type O1 material specification. It measures 0.25 inches thick, 14 inches wide, and 18 inches long, and weighs 18.04 pounds. O1 tool steel is a versatile, oil-quenched grade known for its dimensional stability during heat treatment, making it a standard choice for dies, punches, gauges, and cutting tools. Machinists, toolmakers, and metalworking shops stock this material as a ready-to-machine blank for precision tooling and fixture applications.

This flat stock is suited for job shops, tool and die operations, and maintenance machine shops requiring a reliable, pre-cut O1 tool steel blank. The generous 14-inch width and 18-inch length provide enough material to lay out multiple tooling components from a single piece. Its tight thickness and squareness tolerances make it appropriate for applications where dimensional accuracy before heat treat is critical.

Installation Notes

Cutting, grinding, and heat treating of tool steel should be performed by qualified machinists or toolmakers familiar with O1 oil-hardening procedures. Always wear appropriate PPE when machining or cutting tool steel stock. Follow established heat treatment procedures for O1 grade, including proper preheat, hardening temperature, and oil quench, using equipment rated for the application. Allow material to reach ambient temperature before final dimensional inspection.
