Drill Rod Tool Steels 85997955 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85997955 is an A2 air-hardening tool steel flat stock bar sized at 0.125 inches thick, 0.25 inches wide, and 18 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good wear resistance. This flat stock is precision-ground to tight tolerances, making it suitable for toolmakers, machinists, and die makers who need consistent stock for fabricating punches, dies, gauges, and similar toolroom components. The piece weighs approximately 0.16 pounds and ships as a single unit.

This flat stock is used in machine shops, toolrooms, and manufacturing environments where close-tolerance raw material is required before final machining and heat treatment. Common applications include the fabrication of custom cutting tools, fixture components, small dies, and precision gauges. At 0.125 inches thick and 0.25 inches wide, this bar is suited to small-section tool and die work where tight width and thickness tolerances are critical to final part performance.

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for general toolroom and die-making applications requiring cold-work tool steel in small flat-bar form.

Installation Notes

A2 tool steel flat stock is worked by machinists and toolmakers using conventional milling, grinding, and EDM equipment. Heat treatment should follow AISI A2 guidelines for austenitizing, air quenching, and tempering and is typically performed by a qualified heat treater. Always wear appropriate personal protective equipment when cutting or grinding tool steel. Inspect stock dimensions before machining to confirm they meet your application tolerances.
