Value Collection 35574250 Tool Steel Round 7/8 in A2

Product Description

The VALUE COLLECTION 35574250 is a decarb-free A2 air-hardening tool steel round bar stock intended for toolmakers, machinists, and die makers who need a ready-to-machine blank with a clean, oxide-free surface. At 7/8 inch in diameter and 3 feet in overall length, this round bar ships at stock length and requires no additional surface preparation before grinding or machining to final dimension. A2 tool steel offers a balanced combination of wear resistance, toughness, and dimensional stability during heat treatment, making it a dependable choice for punches, dies, gages, and similar precision tooling applications.

This round bar is suited for job shops, tool and die operations, and maintenance departments that fabricate or repair custom tooling in-house. The decarb-free condition means the outer surface retains its full carbon content, eliminating the need to rough-machine away a decarburized layer before heat treatment. Typical applications include blanks for cold-work dies, form punches, drill bushings, and fixture components where close tolerances and post-heat-treat grinding are planned.

Key Features

• Decarb-free surface condition preserves full carbon content to the outer diameter
• A2 air-hardening grade provides good dimensional stability and reduced distortion during heat treatment compared to oil-hardening grades
• 7/8 inch diameter with a ground tolerance of +0.005 to -0.015 inch for consistent fitment in standard toolholders and bushings
• 3-foot stock length allows multiple blanks to be cut from a single bar
• Ready-to-use stock length format minimizes lead time for in-house tooling fabrication

Compatibility

Designed as a standard stock-length A2 tool steel round suitable for use in any toolmaking, die-making, or machining application that specifies 7/8 inch diameter air-hardening tool steel bar stock.

Installation Notes

Cutting and machining of tool steel round bar should be performed by a qualified machinist using appropriate cutting speeds and coolant for the material grade. Heat treatment of A2 tool steel requires controlled atmosphere or vacuum furnace equipment to maintain the decarb-free condition; consult the material manufacturer's heat treatment data sheet for austenitizing temperature and quench procedure. Always wear appropriate PPE when sawing or grinding tool steel. Follow applicable shop safety codes and procedures when handling bar stock of this length and weight.
