Value Collection 07181 D-2 Tool Steel Drill Rod 5/16in X 36in

Product Description

The VALUE COLLECTION 07181 is a D-2 air hardening tool steel drill rod sized at 5/16 inches in diameter and 36 inches in length. D-2 tool steel is a high-carbon, high-chromium cold-work steel known for excellent wear resistance and dimensional stability during heat treatment. Air hardening means the rod hardens through controlled air cooling rather than quenching in oil or water, which reduces the risk of warping and cracking during the hardening process. This drill rod stock is used by machinists, tool and die makers, and fabrication shops as raw material for punches, dies, gauges, and custom tooling applications. It weighs 0.78 pounds per piece.

D-2 drill rod in this diameter and length is a standard choice for small-diameter tooling blanks in job shops and production toolmaking environments. The 5/16 inches diameter suits applications requiring precise, ground-to-tolerance round stock that can be machined, ground, and then heat treated to final hardness. It is commonly used in the fabrication of forming dies, cutting tools, and wear components where long tool life under abrasive conditions is required.

Key Features

• D-2 tool steel grade with high wear resistance suitable for cold-work tooling applications
• Air hardening alloy minimizes distortion and cracking risk during heat treatment
• Ground round stock at 5/16 inches diameter for close-tolerance machining and grinding
• 36 inches overall length provides sufficient stock for multiple tooling blanks per rod
• Lightweight at 0.78 pounds for easy handling and storage

Compatibility

Designed as a standard D-2 air hardening tool steel drill rod blank suitable for general toolmaking and die-making applications where close-tolerance round stock is required.

Installation Notes

Cutting and machining of tool steel drill rod should be performed by qualified machinists using appropriate cutting tools and speeds for high-alloy steel. Heat treatment, including hardening and tempering of D-2 steel, should be carried out by a qualified heat treater following the steel manufacturer's recommended thermal cycles. Always use appropriate personal protective equipment when cutting, grinding, or machining tool steel stock. Secure the rod properly in a vise or chuck before cutting to prevent movement.
