Product Details

The Starrett 54109 is a precision-ground flat stock made from AISI O1 oil-hardening tool steel, measuring 5/16 inch thick by 3 inches wide by 18 inches long. This premium tool steel is ideal for manufacturing cutting tools, gauges, jigs, fixtures, and other precision tooling applications.

Key Features:

  • AISI O1 oil-hardening tool steel composition for excellent wear resistance
  • Dimensionally stable during heat treatment, minimizing distortion
  • Suitable for intricate work and thin sections with minimal risk of cracking
  • Precision-ground flat stock for accurate dimensions
  • Hardens to Rockwell C 57-62 when properly heat treated
  • Excellent machinability in the annealed condition

O1 tool steel is one of the most popular and versatile tool steels available, offering a balanced combination of toughness, wear resistance, and ease of heat treatment. This flat stock can be machined, drilled, and shaped to your specifications before hardening, making it an excellent choice for custom tooling and precision components.

Amazing prices and shipping rates

I'm very satisfied with my purchase for the 2nd time. I will be making more purchases in a few months.

Your selection and service is great. The only issue i had was knowing if the product i was ordering was a stock item. I had to contact your customer service about three days after ordering to get an estimated delivery time, would have been nice to know sooner.

Best pricing and super easy checkout!

Fast service and shipping.
