Value Collection 35574276 A2 Tool Steel Round Bar 1-1/8 in

Product Description

The VALUE COLLECTION 35574276 is a decarb-free A2 air-hardening tool steel round bar stocked at 3 feet in length with a 1-1/8 inch diameter. Decarb-free stock means the outer surface retains the same carbon content as the core, eliminating the need to grind away a decarburized layer before use. A2 tool steel offers a balanced combination of wear resistance, toughness, and dimensional stability during air hardening, making it a reliable choice for toolmakers, machinists, and die shops working to close tolerances. Diameter tolerance is held to +0.005 to -0.015 inch.

This round bar is suited for fabrication of punches, dies, gauges, knives, and general tooling components in machine shops and tool rooms. The stock length format makes it practical for job-shop use where material is cut to finished blank dimensions before machining and heat treatment. It is commonly specified in applications where air-hardening characteristics reduce distortion risk compared to oil-hardening grades.

Key Features

• Decarb-free surface — no material removal required to reach full-carbon stock
• A2 air-hardening tool steel grade for reduced distortion during heat treatment
• 1-1/8 inch diameter with tight tolerance of +0.005 to -0.015 inch
• 3-foot stock length ready for cut-to-blank machining operations
• Suitable for punches, dies, gauges, and precision tooling components

Compatibility

Designed as a standard stock-length A2 tool steel round bar for use in general toolmaking, die making, and machining applications requiring air-hardening material at 1-1/8 inch diameter.

Installation Notes

Cutting and machining of tool steel round bar should be performed by qualified machinists using appropriate cutting speeds and tooling for hardened or semi-hardened stock. Heat treatment of A2 tool steel should follow established metallurgical procedures for air-hardening grades, including proper austenitizing temperature and controlled cooling. Personal protective equipment appropriate for metal cutting and grinding operations is required. Consult applicable shop safety standards before cutting or processing.
