Value Collection O1D266 O-1 Tool Steel Drill Rod

Product Description

The VALUE COLLECTION O1D#266 is an O-1 oil hardening tool steel drill rod measuring 0.146 inches in diameter and 36 inches in length. Drill rod stock in O-1 grade is a general-purpose tool steel valued for its ability to be precision-ground to tight tolerances before hardening. It machines well in the annealed state and achieves excellent hardness and wear resistance after oil quenching. This rod is used by machinists, toolmakers, and die makers to fabricate punches, dies, gauges, pins, and other tooling components. At 0.171 pounds, it is a single-piece cut suited for light tooling and small component work.

O-1 drill rod at this diameter suits applications requiring tight dimensional accuracy in the stock condition. It is a common starting material in tool and die shops, maintenance machining environments, and trade training programs. The 36-inch length provides enough stock for multiple shorter tool blanks or a single long-form component such as a punch guide or alignment pin. This size corresponds to a Number 26 drill size diameter of 0.146 inches, making it a direct match for applications where that specific bore or shaft dimension is required.

Key Features

• O-1 oil hardening grade tool steel for predictable hardening response and minimal distortion during quench
• Precision-ground to 0.146 inches diameter for close-tolerance tooling work
• 36-inch overall length provides versatile stock for multiple tool blanks
• Annealed condition allows machining, drilling, and grinding prior to heat treatment
• Lightweight at 0.171 pounds for easy handling and workholding

Compatibility

Designed as a general-purpose O-1 oil hardening tool steel drill rod for use in tool and die fabrication, punch and die sets, gauge pins, and similar machined tooling components requiring a 0.146-inch diameter stock diameter.

Installation Notes

Cutting, grinding, and machining of tool steel rod should be performed by a qualified machinist or toolmaker using appropriate cutting fluids and personal protective equipment. Heat treatment and oil quenching of O-1 steel should follow established metallurgical procedures for this grade and be performed in a controlled shop environment. All grinding and cutting operations should comply with applicable shop safety standards. Avoid bending or over-stressing the rod in the annealed condition, as it is intended for machined-component use rather than structural load bearing.
