Starrett 54110 Precision Ground Flat Stock 5/16" x 3-1/2" x 18" AISI O1 Tool Steel

The Starrett 54110 is a precision ground flat stock made from AISI O1 oil-hardening tool steel, measuring 5/16" thick x 3-1/2" wide x 18" long. This high-quality tool steel is ideal for toolmaking, die work, and precision machining applications requiring dimensional stability and hardness.

Key Features:

• AISI O1 oil-hardening tool steel for superior wear resistance and edge retention
• Precision ground to tight tolerances for consistent dimensions
• Dimensionally stable during heat treatment with minimal warping
• Excellent machinability in the annealed state
• Suitable for intricate work including thin sections with minimal cracking risk
• Can be hardened to Rockwell C 57-62 when properly heat treated

O1 tool steel is a versatile, economical choice for making cutting tools, punches, dies, gauges, and machine parts where high hardness and wear resistance are required. The precision ground finish eliminates additional stock removal for most applications.
