Drill Rod Tool Steels 58102 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 58102 is an O1 oil-hardening tool steel flat stock bar conforming to AISI Type O1 material specification. It measures 5/16 inches thick, 1-3/4 inches wide, and 36 inches long, with a shipping weight of 5.64 pounds. O1 tool steel is a general-purpose oil-hardening grade known for its dimensional stability during heat treatment, good machinability in the annealed state, and ability to hold a sharp edge after hardening. This flat stock is cut to a standardized bar form ready for machining, grinding, and heat treatment by toolmakers, machinists, and die makers working in production or job-shop environments.

This flat stock is suited for fabricating cutting tools, punches, dies, gauges, jigs, and fixtures where moderate toughness and good wear resistance are required. The annealed condition allows straightforward machining before oil-quench hardening. Typical applications include tool-and-die shops, machine shops, and maintenance departments requiring a reliable stock material for custom tooling. The 36-inch length provides usable stock for multiple smaller blanks or a single longer component without additional splicing.

Installation Notes

Machining and heat treatment of O1 tool steel should be performed by qualified toolmakers or machinists familiar with oil-hardening procedures. Always anneal the stock before heavy material removal and follow established quenching protocols using the appropriate oil medium to avoid cracking. Wear appropriate PPE during cutting, grinding, and heat treatment operations. Consult the material safety data sheet and relevant shop safety standards before processing.
