Drill Rod Tool Steels 860122 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 860122 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a reliable, dimension-controlled steel blank ready for layout, cutting, and heat treatment. Measuring 3/64 inches thick, 3/4 inches wide, and 36 inches long, this flat stock conforms to AISI Type O1 Oil Hardening material specification. Thickness tolerance is held to plus or minus 0.001 inches, giving precision-sensitive applications a consistent starting point before grinding or machining to final dimension. The bar ships at approximately 0.36 pounds per piece.

O1 tool steel flat stock is a shop staple for fabricating punches, dies, form tools, blades, gauges, and fixtures where moderate oil-quench hardening is required after machining. The 36-inch length accommodates most benchtop layout and blanking operations without additional cutting. The narrow 3/64-inch thickness makes this bar well suited for thin blade blanks, shim-stock tooling, and small die components in both job-shop and toolroom environments.

Key Features

• AISI Type O1 Oil Hardening tool steel - hardens with oil quench for consistent results
• Thickness held to plus or minus 0.001 inches for precision fitment before final grinding

• Length tolerance of plus 0.5 inches - allows clean squaring of ends
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• Weighs approximately 0.36 pounds - easy single-piece handling

Compatibility

Designed as a standard O1 oil-hardening tool steel flat bar for general toolroom and die-shop applications where AISI Type O1 material specification is required.

Installation Notes

Machining and heat treatment of O1 tool steel should be performed by a qualified machinist or toolmaker familiar with tool steel handling procedures. Always anneal stock before machining if hardness is unknown, and follow the material manufacturer's recommended preheat, hardening, and tempering cycles for AISI O1. Secure the workpiece properly in a vise or fixture before cutting. Personal protective equipment including eye protection and cut-resistant gloves is required when handling flat stock.
