Trending 9/16″ X 1 1/2″ X 18″ Starrett Precision Ground Flat Stock AISI O-1 Oil Hardened Steel 54170

9/16″ X 1 1/2″ X 18″ Starrett Precision Ground Flat Stock | AISI O-1 Oil Hardened Steel | 54170 is Starrett precision ground flat stock, supplied ground flat, square and parallel in aisi o-1 oil hardened steel so it goes straight into layout, fixturing and machining work without further surfacing.

Precision ground surface ensures consistent flatness along the entire length for accurate machining and finishing.

AISI O-1 oil hardened steel offers a balance of hardness and machinability; oil hardened heat treatment provides dimensional stability during cutting operations.

One piece stock eliminates joints, reducing risk of misalignment in custom tooling and fixtures.

Ideal for blade stock, punches, dies, jigs, and general metalworking fabrications where a stable, straight stock is required.

Stated dimensions facilitate straightforward stock shaping, drilling, and milling without pre-fitting work.
