Starrett Precision Ground Flat Stock Tool Steel

Starrett Precision Ground Flat Stock is AISI O1 oil-hardening tool steel, also called gage stock or ground flat stock. It is made for toolmakers, machinists, and fabricators who need accurate, ready-to-use material for tooling and fixtures.

Key Features:

• AISI O1 tool steel: This general-purpose oil-hardening grade machines well and heat treats predictably.
• Precision ground surfaces: Ground faces and edges give consistent thickness and flatness. This reduces the finishing work needed before use.
• Heat-treatable: You can harden the steel after machining to get good wear resistance and edge retention.
• Starrett quality: Starrett has made precision tools and measuring equipment in the USA for generations.

Common Applications:

• Punches and dies
• Jigs and fixtures
• Gauges and templates
• Shims, wear plates, and general tool room work

The product line comes in many thickness and width options, so you can choose the stock that suits your project. Pick the exact size you need from the available variants.
