Drill Rod Tool Steels 03718848 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718848 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require consistent dimensions and reliable heat-treat response. Measuring 0.125 inches thick, 0.75 inches wide, and 36 inches long, this flat stock ships in annealed condition ready for machining before hardening. A2 tool steel is an air-hardening, medium-alloy cold-work steel known for its good dimensional stability during heat treatment, moderate toughness, and wear resistance. It is commonly used to fabricate punches, dies, gages, and cutting tools where through-hardening with minimal distortion is required.

This flat stock suits a wide range of cold-work tooling applications in job shops, tool and die operations, and maintenance machining environments. The 36-inch bar length allows multiple blanks to be cut from a single piece, reducing material waste. Licensed machinists and toolmakers working to close-tolerance part prints will find the published thickness, width, and length tolerances useful for pre-machining stock allowance planning.

Compatibility

Designed as a standard A2 tool steel flat stock bar for use in cold-work tooling, die making, punch fabrication, and precision gage work where AISI A2 material specification is required.

Installation Notes

A2 tool steel flat stock is machined and ground by toolmakers or machinists prior to heat treatment. All grinding, drilling, and profiling operations should be completed in the annealed state before hardening and tempering. Heat treatment of A2 tool steel requires controlled atmosphere or vacuum furnace equipment and should be performed by qualified heat treaters following the material manufacturer guidelines. Handle bar stock with care on machining tables to avoid nicking finished reference surfaces.
