Drill Rod Tool Steels 57916 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57916 is an O1 oil-hardening tool steel flat stock sized at 0.25 inches thick, 8 inches wide, and 36 inches long. Conforming to AISI Type O1 material specification, this flat stock is manufactured from tool steel and held to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.005 inches to 0.000 inches. At 20.62 pounds per piece, it is suited for toolmakers, machinists, and fabricators who require a reliable, machinable steel blank that responds well to oil-hardening heat treatment. It is a standard choice when consistent stock dimensions and predictable hardening behavior are required.

O1 tool steel flat stock of this size is used in job shops, tool-and-die operations, and precision fabrication environments. Common applications include the production of punches, dies, gauges, jigs, fixtures, and cutting tools where the stock must be machined to close tolerances before hardening. The 36-inch length provides sufficient material for multiple workpieces from a single bar, and the 8-inch width accommodates a broad range of tooling blanks without the need to join narrower stock.

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat stock suitable for use in tool-and-die, mold-making, and precision machining applications where AISI Type O1 material specification is required.

Installation Notes

Machining and heat treatment of O1 tool steel flat stock should be performed by qualified machinists or toolmakers familiar with tool steel handling procedures. Always power down and lock out cutting or grinding equipment before securing the workpiece. Oil-hardening heat treatment must follow appropriate thermal cycling procedures per the material specification; consult applicable shop standards or the material data sheet before hardening. Cutting operations should use appropriate speeds, feeds, and coolants suitable for tool steel to avoid work hardening or surface damage.
