Drill Rod Tool Steels 811750 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 811750 is an O1 oil-hardening tool steel flat stock bar intended for precision toolmaking, die work, and machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 0.219 inches thick, 0.219 inches wide, and 18 inches long, with a weight of 0.25 pounds. O1 tool steel is known for its consistent response to oil-hardening heat treatment and its machinability in the annealed state, making it a standard material choice for punches, dies, gauges, and cutting tools in job shops and tool rooms.

This flat stock is suited for professional machinists, toolmakers, and die makers working in job shop, production, or maintenance environments. The 18-inch length is a common cut suitable for small to medium tooling applications. The tight dimensional tolerances make it appropriate for applications where close fits are required before grinding to final dimensions.

Compatibility

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

Installation Notes

O1 tool steel flat stock is machined and ground by skilled toolmakers using conventional milling, turning, and surface grinding equipment. Heat treatment, including oil quenching, should be performed by qualified personnel following AISI O1 heat treat guidelines. Always follow shop safety protocols when cutting or grinding tool steel, including use of appropriate PPE and coolant. Material should be stored flat and dry to prevent corrosion prior to use.
