Drill Rod Tool Steels 57764 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57764 is an O1 oil-hardening tool steel flat bar cut to 3/8 inches thick, 1-3/4 inches wide, and 18 inches long. O1 tool steel is a general-purpose oil-hardening grade known for good wear resistance, machinability, and dimensional stability during heat treatment. This flat stock ships in an annealed condition, ready for machining to a finished tool profile before hardening. Machinists, toolmakers, and die makers commonly use this stock to fabricate punches, dies, gauges, bushings, and other precision tooling components. The piece weighs 3.39 pounds.

This flat stock is suited for short-run tooling and fixture work in job shops, tool rooms, and maintenance departments. The 18-inch length provides enough material for multiple tool blanks or a single longer component. The pre-cut flat format reduces setup time compared to round or square bar when the finished part calls for a flat cross-section. It is appropriate for both manual machining and CNC milling operations prior to heat treatment.

Key Features

• AISI Type O1 oil-hardening tool steel with good wear resistance and machinability
• Tight thickness tolerance of plus or minus 0.001 inches supports precision layout work
• Width tolerance of plus 0.005 inches, minus 0.000 inches ensures stock is never undersize
• Length tolerance of plus 0.25 inches provides working allowance for facing cuts
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Single-piece package suitable for low-quantity tooling projects

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat stock suitable for general toolmaking, die making, and precision fixture fabrication applications requiring oil-quench heat treatment.

Installation Notes

O1 tool steel flat stock is machined by qualified toolmakers or machinists before hardening. All rough machining, drilling, and grinding should be completed in the annealed state prior to oil quench and temper heat treatment. Follow recognized heat treatment procedures and applicable shop safety standards when hardening. Handle freshly hardened pieces with care, as untempered tool steel is brittle.
