Value Collection OR07.0X1 Tool Steel Round 7 in O-1

Product Description

The VALUE COLLECTION OR07.0X1 is a decarb-free O-1 oil-hardening tool steel round bar stocked in a 7-inch diameter by 1-inch length configuration. O-1 is a general-purpose tool steel known for its excellent machinability, good wear resistance after hardening, and dimensional stability during oil-quench heat treatment. The decarb-free condition means the outer surface has been ground or turned to remove the decarburized layer that forms during mill processing, giving machinists a clean, consistent surface to work from without additional stock removal. This bar weighs 12.8 pounds and carries a diameter tolerance of plus 0.070 to plus 0.150 inches with a length tolerance of plus 0.250 to minus 0.000 inches.

This tool steel round is suited for tool and die shops, machine shops, and maintenance facilities that fabricate punches, dies, gauges, jigs, fixtures, and cutting tools. The stock length format makes it practical for short-run tooling work where minimal parting or facing is needed before machining to final form. It is appropriate for both prototype and production tooling applications where oil-hardening heat treatment will be applied after rough machining.

Key Features

• Decarb-free condition eliminates the need to remove an oxidized surface layer before machining
• O-1 oil-hardening grade provides good wear resistance and dimensional stability during heat treatment
• 7-inch diameter supports large-diameter tooling, die blanks, and fixture components
• Diameter tolerance of plus 0.070 to plus 0.150 inches is typical for oversize ground rounds, leaving cleanup stock
• Stock length format at 1 inch minimizes material waste for short-section tooling applications
• Weight Per Foot rated at 137.30 pounds, consistent with standard tool steel density at this cross-section

Compatibility

Designed as a standard O-1 oil-hardening tool steel round for general toolmaking and machining applications where decarb-free bar stock is specified.

Installation Notes

Machining and heat treatment of tool steel rounds should be performed by qualified tool and die makers or machinists familiar with O-1 steel requirements. Appropriate personal protective equipment and machine guarding must be in place when sawing, turning, or grinding this material. Heat treatment including hardening and tempering should follow established metallurgical procedures for O-1 steel and be performed in controlled furnace equipment. Handle with care given the 12.8-pound weight of this piece.
