Value Collection 35574045 O-1 Tool Steel Round Bar 1 in 3 Ft

Product Description

The VALUE COLLECTION 35574045 is a decarburization-free O-1 oil-hardening tool steel round bar intended for toolmakers, machinists, and die shops that require a ready-to-machine blank with a clean, scale-free surface. At 1 inch in diameter and 3 feet in stock length, this bar ships at a finished 9.6 pounds and holds a ground tolerance of +0.005 to -0.015 inch across the diameter. O-1 tool steel offers excellent edge retention and ease of oil-quench hardening, making it a standard choice for punches, dies, gauges, and cutting tools where dimensional stability after heat treatment is critical.

This round bar is suited for general toolroom use in manufacturing, maintenance, and fabrication shops. It is commonly cut to length on a horizontal band saw or cold saw before turning, milling, or grinding to final dimensions. The decarb-free condition means the outer surface has not lost carbon during mill processing, so material removal to finished size is reduced compared to standard hot-rolled stock. Typical applications include custom punches, drill bushings, form dies, and small fixture components in both job-shop and production environments.

Key Features

• Decarburization-free surface condition reduces stock removal before heat treat
• O-1 oil-hardening grade provides predictable, low-distortion hardening response
• Diameter tolerance held to +0.005 to -0.015 inch for close-tolerance blanks
• 3-foot stock length allows multiple parts per bar with standard shop saws
• 9.6-pound bar weight suitable for bench or vise handling without lifting equipment

Compatibility

Designed as a standard O-1 oil-hardening tool steel round stock suitable for general toolroom, die-making, and machining applications where an oil-quenched, decarb-free steel blank is required.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or toolmakers following established shop safety practices. Secure the bar firmly in a vise or chuck before cutting to prevent movement. When hardening, follow the steel supplier recommended oil-quench procedure for O-1 grade and allow the part to temper before placing it in service. Personal protective equipment including eye protection and heat-resistant gloves is required during any hot-work operations.
