Drill Rod Tool Steels 66717 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 66717 is an O1 oil-hardening tool steel flat stock bar intended for toolmaking, jig and fixture fabrication, and precision machining applications. Manufactured to AISI Type O1 specifications, this flat stock measures 0.0625 inches thick, 0.5 inches wide, and 18 inches long, with a weight of 0.16 pounds. The tight thickness tolerance of plus or minus 0.001 inches makes it suitable for work requiring close dimensional control before and after hardening. Machinists, tool-and-die makers, and metalworking shops are the primary installers and end users of this material.

O1 tool steel is a general-purpose oil-hardening grade widely used in the production of cutting tools, punches, dies, gauges, and wear-resistant components. This flat stock format is suited to small-batch machining operations where bar stock is cut, shaped, and then heat-treated to final hardness. The 18-inch length provides a practical working blank for benchtop machining and grinding setups common in job shops and maintenance departments.
