Drill Rod Tool Steels 57765 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57765 is an O1 oil-hardening tool steel flat bar cut to 3/8 inches thick, 2-1/2 inches wide, and 18 inches long. O1 is a general-purpose oil-hardening tool steel known for its dimensional stability during heat treat, good machinability in the annealed state, and ability to hold a sharp edge after hardening. This flat stock ships in the soft, annealed condition and is ready for machining, grinding, or layout work before hardening. Machinists, toolmakers, and die makers use this material to fabricate punches, dies, gauges, knives, and other precision tooling components where consistent tolerances are critical.

This flat stock suits job shop, toolroom, and production environments that require a reliable supply of pre-sized O1 tool steel in manageable bar lengths. The 18-inch length is practical for single-piece blanks or can be cut down for smaller tooling. The 2-1/2-inch width and 3/8-inch thickness cover a wide range of flat tool applications including stripper plates, shim stock blanks, and forming dies. Professionals working to tight dimensional requirements will find the close thickness and squareness tolerances beneficial for fit-up and final grinding operations.

Key Features

• AISI Type O1 oil-hardening tool steel in annealed flat bar form, ready for machining before heat treatment
• Thickness tolerance of plus or minus 0.001 inches for precise fit-up and grinding allowance
• Width tolerance of plus 0.005 inches, minus 0.000 inches, ensuring stock is never undersize on width
• Length tolerance of plus 0.25 inches, providing sufficient material for facing or squaring the ends
• Squareness tolerance of plus or minus 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Package quantity of 1 piece, sold individually with no minimum order beyond one unit

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for toolroom and die shop applications requiring oil-quench heat treatment and close dimensional tolerances.

Installation Notes

Machining and grinding of O1 tool steel should be performed by qualified toolmakers or machinists using appropriate cutting fluids and tooling rated for tool steel. Heat treatment - including hardening and tempering - must follow established metallurgical procedures and should be performed by personnel familiar with oil-quench processes and associated fire and burn hazards. Always allow stock to reach ambient temperature before performing precision measurement. Proper handling procedures for sharp-edged flat bar stock should be observed throughout fabrication.
