Drill Rod Tool Steels 809839 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 809839 is an O1 oil-hardening tool steel flat stock bar sized at 5/64 inches thick, 1-1/2 inches wide, and 18 inches long. Conforming to AISI Type O1 material specification, this flat stock is manufactured from tool steel and held to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus 0.005 inches on width, and plus 0.250 inches on length. Machinists, toolmakers, and metalworking trades use O1 flat stock as a starting material for punches, dies, gauges, cutting tools, and custom fixtures that will later be oil-quench hardened to achieve high wear resistance.

This flat stock is suited for job shop, maintenance, and production toolroom environments where close-tolerance blanks are needed before heat treatment. The 18-inch length provides sufficient stock for most die and punch blank applications. At 0.6 pounds, the piece is easy to handle at the bench or machine. Typical users include tool and die makers, general machinists, and fabrication shops requiring an oil-hardening grade steel that responds predictably to standard hardening and tempering cycles.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable hardening and tempering response
• Thickness tolerance held to plus or minus 0.001 inches for close-fit blanks
• Width tolerance of plus 0.005 inches, zero minus, allowing finish grinding to final size
• Squareness tolerance of plus or minus 0.003 inches on edges for accurate layout work
• 18-inch length with plus 0.250-inch length tolerance accommodates multiple blanks per bar
• Weighs 0.6 pounds, suitable for benchtop handling without rigging

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock blank for toolroom applications requiring oil-quench hardening.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate coolant and tooling rated for hardened or semi-hard steel stock. All heat-treating operations, including oil quenching and tempering, must be carried out in accordance with recognized metallurgical practices for AISI O1 tool steel. Wear appropriate PPE, including eye protection and heat-resistant gloves, when handling stock during or after thermal processing. Ensure work-holding equipment and fixtures are rated for the forces involved in sawing or milling this material.
