Drill Rod Tool Steels 809114 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 809114 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, die makers, and precision fabricators. Produced to AISI Type O1 specifications, this flat stock measures 1/64 inch thick, 2-1/2 inches wide, and 18 inches long. O1 tool steel offers good machinability in the annealed state and responds well to oil-quench hardening, making it a reliable choice for punches, dies, gauges, and cutting tools. Thickness tolerance is held to plus or minus 0.001 inch, supporting close-tolerance work where dimensional consistency is critical before heat treatment.

This flat stock is suited for job shop, toolroom, and prototype applications where small-section O1 material is needed in manageable lengths. The 18-inch length allows for multiple blanks to be cut from a single piece. Width tolerance is plus 0.005 inch, minus 0.000 inch, and length tolerance is plus 0.250 inch, giving fabricators a consistent oversize allowance for finish grinding. Licensed machinists and tool-and-die professionals working in general manufacturing, mold making, and precision metalworking are the primary users of this stock.

Key Features

• AISI Type O1 oil-hardening tool steel meets standard material specification for predictable heat-treat response
• Thickness held to plus or minus 0.001 inch tolerance for close-tolerance toolroom work
• Width tolerance of plus 0.005 inch, minus 0.000 inch provides consistent grinding stock
• Squareness maintained to 0.003 inch on edges and 0.004 inch per inch of thickness on ends
• 18-inch length allows multiple blanks per piece, reducing material waste
• Lightweight at 0.2 pounds, practical for bench and manual handling in small-lot toolroom use

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat stock suitable for toolroom, die-making, and precision machining applications requiring small-section flat bar material.

Installation Notes

Cutting and machining should be performed in the annealed condition using appropriate metalworking tools rated for tool steel. Heat treatment, including oil quenching and tempering, must be performed by qualified personnel following established metallurgical procedures for AISI O1 steel. Always wear appropriate PPE when cutting, grinding, or heat-treating tool steel. Follow applicable shop safety codes and equipment manufacturer guidelines for hardening operations.
