Tool Steel Drill Rod O1

Description
Technical Info

O1 tool steel drill rod is a general purpose, oil hardening tool steel valued for its fine grain structure, excellent machinability, and reliable dimensional accuracy during heat treatment. While it does not offer the wear resistance of A2 or D2, O1 provides superior control over size and shape with significantly reduced distortion. Ground and polished to a 16 Ra surface finish and fully free of decarburization, O1 drill rod is ideal for precision tooling and components requiring predictable hardening behavior.

Applications: Gauges, punches, shear components, knives, tooling fixtures, precision shafts.

Finish / Condition: Ground & Polished (16 Ra, Decarb Free)
