Drill Rod Tool Steels 57876 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57876 is an O1 oil-hardening tool steel flat stock bar designed for toolmaking, die work, jigs, fixtures, and precision machining applications. Conforming to AISI Type O1 specification, this flat stock measures 3/32 inches thick, 6 inches wide, and 36 inches long, with a weight of 5.8 pounds. The tight thickness tolerance of plus or minus 0.001 inches makes it suitable for work requiring close dimensional control. Machinists, tool-and-die makers, and fabricators working in job shops or production environments are the primary users of this material.

O1 tool steel is a general-purpose oil-hardening steel commonly used in cold-work tooling applications. This flat bar is well suited for blanking dies, forming tools, gauges, punches, and similar components where moderate wear resistance and good machinability in the annealed state are required. The 36-inch length provides a standard stock dimension that allows multiple parts to be cut from a single piece with minimal waste. This material is supplied in the annealed condition and is intended to be machined, then heat-treated by the end user.

Key Features

• AISI Type O1 oil-hardening tool steel construction for reliable cold-work tooling performance

• Width tolerance of plus 0.005 inches to minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Supplied in annealed condition for machining prior to heat treatment

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for cold-work tooling, die making, gauging, and precision fixture applications where this material specification is required.

Installation Notes

This material is typically processed by machinists and tool-and-die makers using conventional milling, grinding, and sawing equipment. Heat treatment, including oil quenching, should be performed by a qualified heat treater following established practices for AISI O1 tool steel. Always follow appropriate shop safety procedures when cutting and grinding tool steel, including use of proper PPE. Verify final dimensions after machining and before heat treatment to account for any distortion during the hardening process.
