Starrett 54263 O1 Tool Steel Flat Stock 1/16x2x36 in

Product Description

The STARRETT 54263 is an O1 oil-hardening tool steel flat stock bar measuring 1/16 inch thick, 2 inches wide, and 36 inches long. Manufactured to AISI Type O1 material specification, this flat stock is held to tight dimensional tolerances: plus or minus 0.001 inches on thickness, 0.000 to minus 0.005 inches on width, and plus 0.015 inches on length. Edge squareness is held to 0.003 inches per inch. The stock ships in annealed condition, ready for machining, grinding, and custom tooling work. Machinists, tool and die makers, and industrial maintenance professionals use this material for fabricating punches, dies, gauges, and cutting tools.

O1 tool steel flat stock in this size is suited for light-duty tooling applications where a thin, wide profile is needed before hardening. Typical uses include making form cutters, blanking dies, scrapers, and precision templates. The 36-inch length provides sufficient material for multiple short blanks or one longer workpiece. Because O1 is oil-quenched during hardening, it exhibits lower distortion compared to water-hardening grades, making it a practical choice for close-tolerance toolroom parts fabricated in job shops and maintenance departments.

Key Features

• Thickness held to plus or minus 0.001 inches for consistent stock removal during grinding
• Edge squareness of 0.003 inches per inch on all edges
• Width tolerance of 0.000 to minus 0.005 inches ensures parts fit planned layouts
• 36-inch length yields multiple blanks from a single piece
• Sold individually, minimum order quantity of 1

Compatibility

Designed as a general-purpose O1 tool steel flat stock bar suitable for toolroom, die shop, and industrial maintenance applications requiring oil-hardening stock in a thin, wide flat profile.

Installation Notes

Cutting and grinding of tool steel flat stock should be performed by a qualified machinist using appropriate tooling for hardened or pre-hardened steel materials. Always wear eye protection and use proper workholding when sawing or surface grinding. Heat treatment, including oil quenching and tempering, should follow established AISI O1 procedures and be performed by personnel familiar with tool steel metallurgy. Verify final dimensions after heat treatment, as some dimensional change may occur during hardening.
