Drill Rod Tool Steels 03718293 A2 Flat Stock 5/16x1-3/4x36in

Product Description

The DRILL ROD TOOL STEELS 03718293 is an A2 air-hardening tool steel flat stock bar measuring 5/16 inches thick, 1-3/4 inches wide, and 36 inches long. A2 tool steel is an air-hardening, cold-work grade known for excellent dimensional stability during heat treatment and good wear resistance. This flat stock is precision-ground to tight tolerances, making it suitable for tool and die makers, machinists, and fabricators who require consistent stock for cutting tools, punches, dies, fixtures, and gauges. At 5.58 pounds, it is a manageable single-length bar ready for layout, machining, or heat treatment.

This flat stock is used in tool rooms, machine shops, and fabrication facilities where cold-work tooling applications demand a stable, machinable steel before hardening. A2 grade is a common choice for blanking dies, forming dies, trim dies, and precision fixtures in both job-shop and production environments. It is appropriate for applications requiring moderate toughness combined with good abrasion resistance after hardening. Machinists and tool and die makers typically work this material in the annealed condition before sending it through air-hardening heat treatment.

Key Features

• AISI A2 air-hardening tool steel - stable dimensions during heat treatment compared to oil-hardening grades
• Tight thickness tolerance of plus or minus 0.001 inches for precision tooling applications
• Width tolerance of plus 0.000 to plus 0.005 inches for consistent fit in die sets and fixtures
• Length tolerance of plus or minus 0.250 to 0.500 inches on the 36-inch bar
• Square tolerance of plus or minus 0.003 inches ensures flat, true stock straight from the bar
• Single-piece minimum order quantity - no bulk commitment required

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock for cold-work tooling applications including dies, punches, gauges, and fixtures where AISI A2 material specification is required.

Installation Notes

A2 tool steel flat stock is machined and fabricated by qualified tool and die makers or machinists using appropriate metal-cutting equipment. Material should be worked in the annealed condition prior to heat treatment. Air hardening requires controlled furnace heating and still-air or fan-assisted cooling - do not quench in oil or water. Always follow applicable shop safety procedures and heat-treatment equipment manufacturer guidelines when processing tool steel.
