Starrett Precision Ground Flat Stock A2 Tool Steel

Starrett Precision Ground Flat Stock in A2 tool steel (also called A2 air-hardening ground flat stock or ground tool steel bar) is made for toolmakers, machinists and die shops. It is ground straight and parallel, so it is ready for layout, fixturing and machining work. Starrett also uses its own ground flat stock for many of its precision tool parts.

Key Features:

• A2 air-hardening tool steel: contains about 5% chromium and offers high wear and abrasion resistance.
• Dimensionally stable: holds close dimensional accuracy through heat treating. The wide hardening range makes the process forgiving.
• Precision ground: ground straight and parallel for accurate, repeatable setups.
• Full-length identification: marking along the bar helps avoid mix-ups with other steels.
• Long tool life: the chromium content suits punches and dies in long production runs.

Typical Applications:

• Punches and dies
• Gauges, fixtures and jigs
• Precision tooling components, shims and spacers

Starrett A2 ground flat stock gives shops a consistent, reliable starting material for precision tooling and machining projects.
