Drill Rod Tool Steels 57794 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57794 is an O1 oil-hardening tool steel flat stock bar sized at 0.5 inches thick, 12 inches wide, and 18 inches long. Manufactured to AISI Type O1 specification, this flat stock is intended for toolmaking, die work, jigs, fixtures, and precision machining applications where tight dimensional tolerances and consistent hardening response are required. At 30.92 pounds, this is a substantial piece suited to professional shop environments. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where close stock removal and predictable heat treatment are critical.

O1 tool steel flat stock of this size is typically used in machine shops, tool-and-die operations, and industrial fabrication settings. The 12-inch width and 18-inch length make it practical for blanking out large die plates, wear plates, or precision fixtures. Machinists and toolmakers working with oil-quench heat treatment processes will find this stock dimensionally consistent and ready for layout and rough machining before hardening.

Compatibility

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

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. O1 tool steel requires oil quench heat treatment; follow established metallurgical procedures and consult material safety data for handling during heat treat operations. Use proper lifting equipment when handling pieces of this weight. Secure workpieces firmly before any machining or cutting operation.
