Value Collection SR.75X12 S-7 Tool Steel Round 0.75x12 in

Product Description

The VALUE COLLECTION SR.75X12 is a decarburization-free tool steel round bar machined to S-7 shock-resistant (Hi-Shock) grade specifications. Measuring 0.75 inches in diameter and 12 inches in overall length, this bar stock is held to a diameter tolerance of +0.010 to +0.020 inches, giving machinists and toolmakers a reliable, oversized starting point for grinding to final dimension. S-7 tool steel is valued for its combination of high impact toughness and moderate wear resistance, making it well suited for tooling that must absorb repeated shock loading without fracturing. The decarb-free condition means the outer surface retains its full carbon content, reducing the need for additional stock removal before heat treatment or precision grinding.

This round stock is intended for use in tool and die shops, maintenance machining operations, and industrial fabrication environments where S-7 material is specified. Typical applications include punches, chisels, hot-work tooling components, and shock-loaded die inserts. The 12-inch stock length suits short-run tooling work and prototype part production. This material is worked by machinists, tool and die makers, and maintenance technicians with access to appropriate metal-cutting and grinding equipment.

Key Features

• Decarb-free surface condition preserves carbon content for consistent heat-treat response
• S-7 (Hi-Shock) grade provides high impact toughness for shock-loaded tooling applications
• Diameter tolerance of +0.010 to +0.020 inches allows grinding to final size
• Length tolerance of +0.250 to -0.000 inches ensures stock length meets or exceeds nominal
• 0.75 inch diameter by 12 inch length suits punches, chisels, and short-run die components
• Sold as individual piece with no minimum quantity beyond single-unit ordering

Compatibility

Designed as a general-purpose S-7 grade tool steel round bar suitable for tool and die applications requiring shock-resistant material in 0.75 inch diameter stock form.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool and die makers using appropriate personal protective equipment. Follow established shop procedures and relevant ANSI or OSHA guidelines for metal cutting operations. Allow the bar to reach ambient temperature before taking critical measurements, as thermal expansion affects dimensional readings. Post-machining heat treatment, if required, should follow the material manufacturer's recommended cycles for S-7 grade steel.
