5/8″ X 4″ X 18″ Starrett Oversize Precision Ground Flat Stock AISI O-1 Oil Hardened Steel 57039 Bargain

Oversize precision ground flat stock crafted from AISI O-1 oil hardened steel. This single piece stock provides a stable blank for tooling, blades, and fixtures that require tight flatness and consistent thickness.

Precision ground flat faces deliver consistent thickness and surface straightness, reducing setup time during milling, grinding, or broaching.

AISI O-1 oil hardened steel offers balanced machinability and edge retention for tool blanks and die making.

Oversize stock provides material for final shaping and finishing while preserving tool-facing surfaces from initial rough work.

One piece construction eliminates seams or welds, improving rigidity for jigs and fixtures.

Suitable for secondary operations such as grinding, shaping, and polishing to achieve final specifications.
