Value Collection PR01.25X12 A2 Tool Steel Round 1.25x12 in

Product Description

The VALUE COLLECTION PR01.25X12 is a decarb-free A2 air-hardening tool steel round bar stocked for toolmakers, die makers, and machine shops that need ready-to-machine stock. At 1.25 inches in diameter and 12 inches in overall length, this round ships with an oversize diameter tolerance of +0.010 to +0.020 inches, which preserves a full surface layer free of decarburization so machinists can cut directly to finish dimensions without first grinding away a degraded skin. A2 tool steel offers a balanced combination of wear resistance, toughness, and dimensional stability during air hardening, making it a practical choice for punches, dies, gauges, and fixtures.

This round bar is suited for job shops, tool-and-die operations, and maintenance departments that need short-run stock for prototype or replacement tooling. The 12-inch stock length covers a wide range of small-part applications. Because the diameter is held to a consistent oversize tolerance, the bar is compatible with standard lathe turning and surface grinding workflows without the need for preliminary skin passes to remove decarburized material. Industrial supply distributors and machine shop consumable buyers are the primary purchasers of this item.

Key Features

• Decarb-free surface — oversize diameter tolerance of +0.010 to +0.020 inches eliminates the need to remove a decarburized skin before finish machining
• A2 air-hardening tool steel grade — offers good dimensional stability and wear resistance after heat treatment
• 1.25-inch diameter, 12-inch overall length — convenient stock size for punches, dies, and small fixture components
• Length tolerance of +0.250 to -0.000 inches — stock length guaranteed at nominal or longer
• Single-piece minimum order quantity — no mandatory bulk purchase required

Compatibility

Designed as a standard stock-length A2 tool steel round bar suitable for machining, grinding, and heat-treat applications typical of tool-and-die and general machine shop use.

Installation Notes

Cutting and machining of tool steel round bar should be performed by qualified machinists using appropriate feeds, speeds, and cutting fluids for high-carbon alloy steel. Heat treatment of A2 tool steel requires controlled atmosphere or vacuum furnace equipment to maintain the decarb-free condition; consult the material manufacturer heat-treat data sheet for austenitizing temperatures and quench procedures. Wear appropriate PPE when cutting or grinding. Verify bar dimensions against your drawing tolerance before machining to final size.
