Value Collection 10220 O1 Tool Steel Flat Stock 10x30x1000mm

Product Description

The VALUE COLLECTION 10220 is an O1 oil-hardening tool steel flat stock bar commonly used in toolmaking, die making, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 10 mm thick, 30 mm wide, and 1000 mm long, with a package weight of 5.19 pounds. The tight dimensional tolerances — plus 0.05 mm on thickness, plus 0.2 mm on width, and plus 0.5 to 0.8 mm on length — make it suitable for applications where dimensional accuracy matters before and after heat treatment. Machinists and tool and die professionals are the primary users of this material.

O1 tool steel flat stock in this size range is well suited for fabricating punches, dies, blades, gauges, and general-purpose cutting tools. The oil-hardening characteristic of O1 minimizes distortion during the quench cycle compared to water-hardening grades, making it a practical choice for shop-machined tooling components. This bar stock is sold in individual lengths and is intended for further machining, grinding, or heat treatment as part of a production or prototype tooling workflow.

Compatibility

Designed as a general-purpose O1 tool steel flat bar for use in toolmaking, die making, and precision machining applications requiring AISI Type O1 oil-hardening material.

Installation Notes

This material is typically processed by machinists or tool and die makers using standard milling, grinding, and turning equipment. Heat treatment should be performed by qualified personnel following established procedures for AISI O1 tool steel, including proper preheat, austenitizing, and oil quench steps. Always allow the material to reach ambient temperature before precise measurement, and handle with appropriate personal protective equipment when edges are sharp after machining.
