Drill Rod Tool Steels 58010 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 58010 is an O1 oil-hardening tool steel flat stock bar measuring 1 inch thick, 6 inches wide, and 36 inches long. Conforming to AISI Type O1 specifications, this flat stock is machined and ground to tight dimensional tolerances, making it suitable for toolmakers, machinists, and die makers who need a reliable starting blank for punches, dies, gauges, and cutting tools. At 61.86 pounds, this is a full-size bar intended for shop use where dimensional accuracy and consistent hardenability are required. The O1 grade is widely recognized for its good machinability in the annealed state and predictable response to oil-quench hardening.

O1 tool steel flat stock at this size is used primarily in tool and die shops, maintenance shops, and manufacturing facilities. Typical applications include fabricating blanking dies, stamping tools, jigs, fixtures, and precision gauges. This bar is supplied in the annealed condition, allowing it to be machined to near-final dimensions before hardening and tempering. The 36-inch length provides sufficient stock for multiple parts or a single large tooling component.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable, controlled hardening response
• Thickness tolerance of plus or minus 0.001 inches for precise dimensional control
• Width tolerance of plus 0.005 inches to minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness tolerance of plus or minus 0.003 inches on edges; 0.004 inches per inch of thickness on ends
• Supplied in annealed condition for machinability prior to heat treatment

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat bar suitable for general tool and die fabrication applications requiring a 1 inch by 6 inch cross-section blank.

Installation Notes

Machining and heat treatment of O1 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel processing procedures. Always follow shop safety protocols when cutting, grinding, or handling large steel bar stock of this weight. Heat treatment, including hardening and tempering cycles, should follow established metallurgical guidelines for AISI O1 steel and must be performed with appropriate furnace equipment. Secure the bar properly during machining operations to prevent movement due to its weight.
