Value Collection 35574508 D2 Tool Steel Round Bar 1-1/4 in

Product Description

The VALUE COLLECTION 35574508 is a decarb-free D2 air-hardening tool steel round bar intended for toolmaking, die work, and precision machining applications. Supplied at 1-1/4 inches in diameter and 3 feet in overall length, this round stock arrives without a decarburized surface layer, which means the outer material retains the same carbon content as the core. That matters when grinding or machining close to final dimensions. D2 is a high-carbon, high-chromium tool steel known for excellent wear resistance and dimensional stability during heat treatment. It is suited for work where abrasion resistance and edge retention are priorities.

This round bar is used in tool and die shops, machine shops, and maintenance departments that fabricate punches, dies, gauges, forming tools, and wear parts. The stock length format makes it practical for sawing to custom blanks before rough machining and heat treatment. D2 in round bar form is a common starting stock for air-hardening applications where distortion during hardening must be minimized. Licensed machinists, tool and die makers, and industrial maintenance technicians are the typical end users.

Key Features

• Decarb-free surface retains full carbon content to the outer diameter, reducing material removal requirements before heat treat
• D2 grade air-hardening tool steel provides high wear resistance and good dimensional stability through the hardening cycle
• 1-1/4 inch diameter round bar in 3-foot stock length suits a range of blank sizes without excessive saw loss
• Diameter tolerance of +0.005 to -0.015 inches supports consistent fitment in standard tool holder and fixture setups
• Single-piece minimum order quantity allows procurement of individual lengths without a volume commitment

Compatibility

Suited for use as raw stock in fabrication of punches, dies, gauges, and wear components where D2 air-hardening tool steel is specified. Compatible with conventional machining, EDM, and grinding operations standard to tool and die production.

Installation Notes

Cutting and machining of tool steel round bar should be performed by qualified machinists using appropriate personal protective equipment and properly rated cutting tools. Secure workpieces firmly in a vise or chuck before sawing or turning to prevent movement. Heat treatment of D2 steel, including austenitizing and tempering, should follow the material manufacturer's published thermal processing guidelines and is typically performed by a qualified heat treater. Allow material to reach ambient temperature before performing finish grinding or tight-tolerance operations.
