Value Collection 06095640 S-7 Tool Steel Drill Rod 1x36 in

Product Description

The VALUE COLLECTION 06095640 is a 1-inch diameter, 36-inch long drill rod machined from S-7 tool steel, a shock-resisting grade known for high impact toughness combined with good hardness after heat treatment. S-7 is an air-hardening steel, meaning it reaches its hardened state by cooling in still or forced air rather than quench media, which reduces the risk of distortion and cracking during the hardening process. This rod stock is used by machinists, toolmakers, and die makers to fabricate punches, chisels, forming tools, and other tooling components that must absorb repeated impact loads without fracturing. The stock weighs approximately 8.01 pounds per piece.

S-7 drill rod is a standard choice in tool and die shops, maintenance departments, and industrial fabrication environments where high-shock resistance is the primary requirement. Typical applications include impact tools, heavy-duty punches, plastic injection mold components, and pneumatic tool parts. The air-hardening characteristic makes it well suited for complex shapes where dimensional stability during heat treat is critical. This rod is supplied in the annealed condition and requires heat treatment by a qualified professional to achieve final hardness for production tooling use.

Key Features

• S-7 shock-resisting tool steel grade offers high impact toughness with good wear resistance after hardening
• Air-hardening process minimizes distortion and quench cracking compared to oil or water-hardening grades
• 1-inch nominal diameter machined to consistent tolerances for reliable fitment in standard toolholders and fixtures
• 36-inch length provides ample stock for multiple tooling blanks or extended punch applications
• Supplied in annealed condition for ease of initial machining before final heat treatment

Compatibility

Designed as a standard-format drill rod blank suitable for use in tool and die applications requiring S-7 grade shock-resisting tool steel at 1-inch diameter.

Installation Notes

Machining and grinding of S-7 tool steel should be performed by a qualified machinist using appropriate cutting tools rated for tool steel stock. Heat treatment to achieve final hardness must be carried out by a qualified heat treater following established procedures for S-7 air-hardening steel. Always wear appropriate PPE when cutting, grinding, or handling drill rod stock. Consult applicable shop safety standards before processing this material.
