Value Collection NS06164008 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06164008 is an O1 oil-hardening tool steel flat stock bar measuring 1 inch thick, 1 inch wide, and 18 inches long. O1 tool steel is a cold-work, oil-quench grade known for its excellent edge retention, dimensional stability during heat treatment, and machinability in the annealed state. This flat stock is supplied to close tolerances and is intended for use by machinists, tool-and-die makers, and fabricators producing dies, punches, gauges, cutting tools, and precision fixtures. The piece weighs 5.17 pounds and is sold as a single unit.

This flat stock is suited for job-shop and production toolroom applications requiring a readily available O1 bar that can be machined to near-net shape before hardening. Typical uses include blanking dies, forming tools, woodworking blades, jigs, and wear components where a through-hardened tool steel with moderate toughness is appropriate. The 18-inch length provides enough stock for most single-tool applications without requiring a band-saw cutdown from a longer bar.

Key Features

• AISI Type O1 oil-hardening tool steel for controlled heat-treat response and good wear resistance
• Tight thickness tolerance of plus or minus 0.001 inches supports precision layout and grinding
• Width tolerance of plus 0.005 inches minus 0.000 inches for consistent stock removal planning
• Length tolerance of plus 0.25 inches allows for facing or parting to final dimension
• Squareness held to 0.003 inches per inch on edges and 0.004 inches per inch on ends
• Single-piece packaging with a minimum order quantity of one — no bulk commitment required

Compatibility

Designed as a standard O1 oil-hardening tool steel flat bar suitable for general toolroom, die-making, and precision-fixture applications where AISI Type O1 material specification is required.

Installation Notes

O1 tool steel flat stock is machined and ground in the annealed condition using standard toolroom practices before hardening and tempering. Heat treatment should follow established AISI O1 procedures performed by a qualified heat-treater or experienced machinist; improper quench rates or uneven heating can cause distortion or cracking. Use appropriate personal protective equipment when cutting, grinding, or handling sharp-edged stock. Inspect all dimensions against print tolerances before committing to final machining operations.
