Drill Rod Tool Steels 869116 O1 Flat Stock 5/32x3/8x36in

Product Description

The DRILL ROD TOOL STEELS 869116 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a precision-ground blank ready for layout, machining, and heat treatment. The bar measures 5/32 inches thick, 3/8 inches wide, and 36 inches long, with a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.005 minus 0.000 inches. AISI Type O1 material hardens in oil quench, making it well suited for punches, dies, gauges, and small cutting tools where dimensional stability after heat treat is critical.

This flat stock is a general-purpose tool steel bar used in job shops, maintenance departments, and toolrooms for fabricating custom tooling from a soft-annealed blank. The 36-inch length allows multiple pieces to be cut from a single bar. It is appropriate for applications requiring moderate toughness, good wear resistance, and fine-grain structure after hardening. Typical end uses include forming dies, jig components, scrapers, and wear strips in both light industrial and precision machining environments.

Key Features

• AISI Type O1 oil-hardening tool steel - annealed stock ready for machining and subsequent heat treatment
• Tight thickness tolerance of plus or minus 0.001 inches supports precise blank sizing
• Width tolerance of plus 0.005 minus 0.000 inches and length tolerance of plus 0.5 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• 36-inch bar length allows multiple part blanks from a single piece

Compatibility

Designed as a standard AISI Type O1 oil-hardening flat stock bar suitable for general toolmaking applications where O1 tool steel is specified.

Installation Notes

Cutting, grinding, and machining should be performed by a qualified machinist using appropriate tooling for hardened or annealed tool steel. Heat treatment including oil quench and tempering should follow established metallurgical procedures and be performed by qualified personnel with proper equipment. Wear appropriate PPE when cutting or grinding. Verify final dimensions after machining and before hardening, as heat treatment will cause minor dimensional change.
