Value Collection 35574664 S-7 Tool Steel Round 1/2 in 3 Ft

Product Description

The VALUE COLLECTION 35574664 is a decarburization-free S-7 Hi-Shock tool steel round bar stocked in a 3-foot length at 1/2 inch diameter. Decarb-free processing means the outer surface retains the same carbon content and hardness potential as the core, eliminating the need to machine away a sacrificial outer layer before hardening. S-7 is an air- or oil-hardening shock-resisting tool steel known for its high impact toughness and moderate wear resistance. It is widely used in toolmaking, die shops, and industrial maintenance applications where impact loading is a primary concern. The bar ships at a 3-foot stock length and carries a diameter tolerance of +0.005 to -0.015 inches.

This round bar is suited for fabricating punches, chisels, drivers, forming dies, and other tooling that must absorb repeated impact without chipping or cracking. Machine shops, tool-and-die makers, and industrial maintenance teams stock S-7 bar for both new tooling builds and replacement inserts. The 1/2 inch diameter and 3-foot stock length allow efficient blanking of multiple tool blanks from a single piece with minimal material waste.

Key Features

• Decarb-free surface preserves full carbon content for consistent through-hardening response
• S-7 Hi-Shock grade delivers high impact toughness suitable for repeated shock loading
• Diameter tolerance of +0.005 to -0.015 inches supports close-tolerance blank preparation
• 3-foot stock length allows multiple blanks to be cut from a single bar
• Air- or oil-hardening grade compatible with standard tool steel heat treatment practices

Compatibility

Designed as a stock tool steel bar for general toolmaking and die-shop applications requiring S-7 Hi-Shock grade material at 1/2 inch round diameter.

Installation Notes

Cutting, grinding, and machining of tool steel bar stock should be performed by qualified machinists or tool-and-die makers using appropriate coolant to prevent localized overheating. All heat treatment operations including hardening and tempering should follow established S-7 metallurgical guidelines and be performed by personnel trained in tool steel processing. Wear appropriate PPE when cutting or grinding. Verify finished tool dimensions and surface condition before placing tooling into service.
