Starrett 54333 O1 Tool Steel Flat Stock 5/32" x 3-1/2" x 36"

The Starrett 54333 is a precision-ground flat stock made from AISI O1 oil-hardening tool steel, measuring 5/32" thick by 3-1/2" wide by 36" long. This high-quality tool steel is ideal for manufacturing custom cutting tools, punches, dies, gauges, and other precision tooling applications.

Key Features:

• AISI O1 oil-hardening tool steel for superior wear resistance and edge retention
• Precision-ground to tight tolerances for accurate machining
• Dimensionally stable during heat treatment with minimal distortion
• Excellent for intricate work and thin sections with minimal risk of cracking
• Can be hardened to Rockwell C 57-62 for maximum durability
• Suitable for cutting tools, gauges, jigs, fixtures, and custom tooling

O1 tool steel is one of the most versatile and widely-used tool steels, offering an excellent balance of toughness, wear resistance, and machinability. The oil-hardening process provides uniform hardness and allows for precise dimensional control, making it the preferred choice for precision toolmaking and instrument components.
