Starrett 54495 AISI O1 Tool Steel Flat Stock 7/8" x 2" x 36"

The Starrett 54495 is a precision flat stock bar made from AISI O1 oil-hardening tool steel, measuring 7/8 inch thick by 2 inches wide by 36 inches long. This high-quality tool steel is ideal for fabricating custom cutting tools, gauges, jigs, fixtures, and precision tooling components.

Key Features:

• AISI O1 oil-hardening tool steel composition for superior edge retention and wear resistance
• Dimensionally stable during heat treatment with minimal distortion
• Excellent machinability in annealed condition
• Ideal for intricate work and thin sections with minimal risk of cracking
• Can be hardened to Rockwell C 57-62 for demanding applications
• Precision ground flat stock with tight dimensional tolerances

O1 tool steel is a versatile, general-purpose grade that offers an excellent balance of toughness, wear resistance, and ease of heat treatment. It is commonly used for cutting tools, dies, gauges, bushings, and machine parts where dimensional stability and hardness are critical. The oil-quenching process provides uniform hardness with minimal warpage, making it suitable for precision tooling applications.
