Value Collection O1D346 O-1 Tool Steel Drill Rod 0.75 in

Product Description

The VALUE COLLECTION O1D346 is an O-1 oil hardening tool steel drill rod used in toolmaking, die work, and precision machining applications. The rod measures 0.75 inches in diameter and 36 inches in length, providing ample stock for cutting, turning, and grinding to final tool dimensions. O-1 tool steel offers good machinability in the annealed state and develops high surface hardness after oil quenching, making it a practical choice for punches, dies, gauges, and similar tooling. Machinists and toolmakers work with this material on manual and CNC lathes, surface grinders, and mill setups. At 4.54 pounds, the full-length rod is straightforward to handle and fixture.

This drill rod is suited for job shops, tool and die rooms, and maintenance departments that require a reliable, readily machinable tool steel blank. Typical applications include fabricating custom punches, taps, reamers, small dies, and fixture components where moderate wear resistance and good edge retention after hardening are needed. The 36-inch length allows multiple tool blanks to be cut from a single rod, reducing material waste in low-volume production or prototype work.

Key Features

• O-1 oil hardening grade provides good machinability before heat treatment and high hardness after quenching
• 0.75 inch diameter stock suits a wide range of punch, die, and gauge applications
• 36 inch length yields multiple blanks from a single piece
• Ground to close diameter tolerance for use as a dimensional reference or precision blank
• At 4.54 pounds, the rod is manageable for bench and machine setup without lifting aids

Compatibility

Designed as a general-purpose O-1 tool steel drill rod blank for use wherever 0.75 inch diameter oil hardening stock is specified in toolmaking and machining applications.

Installation Notes

Cutting and machining of tool steel rod should be performed by qualified machinists or toolmakers using appropriate personal protective equipment. Secure the workpiece firmly in a chuck or collet before any turning, milling, or cutting operation to prevent kickback. Heat treatment, including oil quenching and tempering, should follow established metallurgical procedures appropriate to O-1 steel and be performed in a controlled environment with proper quench tanks and safety measures. Always allow the rod to reach a stable temperature before beginning precision grinding or finishing operations.
