Drill Rod Tool Steels 57835 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57835 is an O1 oil-hardening tool steel flat stock bar cut to 7/8 inch thick, 6 inches wide, and 18 inches long. O1 is a general-purpose oil-hardening tool steel conforming to AISI Type O1 specification, widely used in toolmaking, die work, and precision machining applications. It offers predictable heat treat response, good dimensional stability after hardening, and excellent machinability in the annealed state. Weighing approximately 27.06 pounds per piece, this flat stock ships ready for layout, machining, or heat treatment. Toolmakers, machinists, and die makers are the primary users of this material.

This flat stock is suited for job shops, tool and die operations, and maintenance departments that require a reliable oil-hardening steel in a ready-to-use bar form. Typical applications include making punches, dies, gauges, jigs, fixtures, and cutting tools. The annealed condition allows for conventional milling, drilling, grinding, and EDM operations prior to hardening. The 18-inch length is a standard off-the-shelf size that accommodates a wide range of toolroom projects without requiring further bar saw operations for shorter workpieces.

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for general toolroom, die-making, and precision machining applications where O1 material specification is required.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate tooling for hardened or annealed steel. Heat treatment, including oil quenching, should follow established metallurgical procedures for AISI O1 tool steel and be performed by personnel familiar with proper quench media, temperature control, and temper cycles. Always wear appropriate PPE when cutting, grinding, or heat treating steel bar stock. Secure workpiece firmly in a vise or fixture before any material removal operation.
