Drill Rod Tool Steels 839614 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 839614 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require a precision-ground blank ready for heat treatment. Manufactured to AISI Type O1 specification, this flat stock measures 3/16 inches thick, 3/8 inches wide, and 18 inches long, with a weight of 0.36 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for close-tolerance tooling applications where dimensional accuracy before hardening is critical.

O1 tool steel flat stock is widely used in general-purpose tooling applications including punches, dies, gauges, knives, and small cutting tools. This bar is sized for benchtop and small-shop work where a short, narrow blank is needed. It ships in the annealed condition, allowing the machinist to finish-grind and machine before performing oil-quench hardening. Suitable for both job shop and production toolroom environments.

Key Features

• AISI Type O1 oil-hardening tool steel for general-purpose tooling and die work
• Precision flat stock with thickness tolerance of plus or minus 0.001 inches
• Width tolerance of plus 0.005 inches, minus 0.000 inches for consistent stock removal planning
• Length tolerance of plus 0.250 inches for usable overcut on each bar
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Annealed condition allows machining and grinding prior to oil-quench hardening

Compatibility

Designed as a standard O1 oil-hardening flat stock blank suitable for general toolroom use wherever AISI Type O1 tool steel in a 3/16 x 3/8 inch cross-section is specified.

Installation Notes

Machining and grinding of O1 tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting fluids and abrasive wheels rated for tool steel. Heat treatment, including oil quenching and tempering, should follow AISI O1 guidelines and be performed in a controlled environment with proper protective equipment. Deburr all edges before hardening to reduce risk of stress cracking. Do not attempt to cold-bend or straighten this material after hardening.
