Drill Rod Tool Steels 03718863 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718863 is an A2 air-hardening tool steel flat stock bar sized at 0.125 inches thick, 1.25 inches wide, and 36 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 supplied in the annealed condition and is intended for fabrication of dies, punches, gauges, and cutting tools. Machinists, toolmakers, and die shops work with this material when close-tolerance tooling is required. The bar weighs approximately 1.82 pounds and carries tight dimensional tolerances that support precision layout and machining work.

This flat bar is suited to tool-and-die shops, maintenance and repair operations, and industrial fabrication environments where A2 air-hardening tool steel is specified. Typical applications include blanking dies, forming dies, slitters, and precision gauges where a balance of toughness and wear resistance is needed. The 36-inch length allows multiple smaller blanks to be cut from a single piece, reducing material waste. The toleranced dimensions support direct use as stock material for milling, grinding, and EDM operations prior to hardening.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate personal protective equipment. Material is supplied in the annealed condition and requires proper heat treatment per the A2 specification to reach working hardness. Follow established shop practices for cutting speeds and feeds when machining tool steel. Consult material safety data sheets for grinding dust and coolant handling requirements.
