Drill Rod Tool Steels 57710 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57710 is an O1 oil-hardening tool steel flat stock bar conforming to AISI Type O1 material specification. It measures 1/16 inches thick, 1-3/4 inches wide, and 18 inches long, with a weight of 0.56 pounds. O1 tool steel is a manganese-chromium-tungsten alloy known for its excellent machinability in the annealed state and its ability to hold a sharp edge after hardening. This flat stock is supplied in the soft, annealed condition and is intended for machining, grinding, and fabrication prior to heat treatment. Toolmakers, machinists, and die shops are the primary users of this material.

This flat stock is suited for producing punches, dies, gauges, knives, woodworking tools, and other precision tooling components where tight dimensional tolerances are required before hardening. The 18-inch length provides a practical starting blank for most bench-scale toolmaking applications. Its relatively thin cross-section at 1/16 inches thick makes it appropriate for flat tooling blanks, shim stock applications, and thin cutting tools. Machine shops and tool-and-die operations working in both prototype and short-run production environments will find this size useful for a range of small-part fabrication tasks.

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat stock suitable for general toolmaking, die-making, and precision machining applications requiring oil-quench heat treatment.

Installation Notes

This material is worked by machinists and toolmakers using conventional milling, turning, drilling, and surface-grinding equipment. Always follow established heat-treatment procedures for O1 tool steel, including proper preheat, austenitizing, and oil-quench sequences, before any finish grinding to final dimension. Wear appropriate PPE when cutting or grinding tool steel. Consult applicable shop safety codes and the material supplier data sheet for full heat-treatment parameters.
