Drill Rod Tool Steels 816018 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 816018 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, jig and fixture fabrication, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 2 inches thick by 4 inches wide by 18 inches long and weighs 42.25 pounds. O1 tool steel offers good wear resistance and machinability in the annealed state, then achieves high hardness after oil quenching. Thickness tolerance is held to plus or minus 0.001 inches, making this stock suitable for applications requiring tight dimensional control before and after heat treat.

This flat stock is used in tool and die shops, mold-making operations, and general metalworking environments where a reliable, oil-hardening grade is specified. Typical applications include blanking dies, forming punches, gauges, and cutting tools. The 18-inch length provides useful workable stock for single-piece or short-run toolmaking. Width and length tolerances allow for cleanup stock when machining to final dimensions. Installation is performed by machinists, toolmakers, and skilled trades professionals working with precision steel stock.

Key Features

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 specification.

Installation Notes

Handling and cutting of tool steel flat stock is performed by qualified machinists or toolmakers using appropriate metal-cutting equipment. Stock should be inspected for squareness and surface condition before layout and machining operations begin. When heat treating, follow the O1 oil-quench procedure per the material supplier guidelines and applicable shop safety protocols. Always use proper lifting equipment when moving stock of this weight.
