Drill Rod Tool Steels 85997237 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85997237 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require precise, consistent stock for fabricating punches, dies, fixtures, and cutting tools. It measures 0.125 inches thick, 2 inches wide, and 72 inches long, and weighs 5.06 pounds per piece. A2 tool steel offers excellent dimensional stability during air hardening, making it a preferred grade where distortion after heat treatment must be minimized. This stock arrives in the annealed condition, ready for machining, grinding, and subsequent heat treatment by a qualified tool and die shop or heat treater.

This flat stock is suited for both job shop and production environments where A2 grade is specified. Typical applications include blanking dies, forming dies, trim dies, gauges, and precision fixtures. The 72-inch length allows multiple blanks to be cut from a single piece, reducing material waste. The close thickness tolerance of plus or minus 0.001 inches and the controlled width tolerance of plus 0.000 to 0.005 inches support accurate machining without requiring excessive stock removal to reach final dimensions.

Key Features

• AISI A2 air-hardening tool steel grade - excellent stability and wear resistance after hardening
• Thickness tolerance held to plus or minus 0.001 inches for consistent stock removal
• Width tolerance of plus 0.000 to 0.005 inches minimizes rework on tight-tolerance parts
• Length tolerance of plus or minus 1 inch - verify actual length before final layout
• Squareness: edge 0.003 inches and ends 0.004 inches per inch of thickness
• 72-inch full-length bar allows multiple blanks per piece, improving yield

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for applications that specify A2 grade material in flat bar form.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by a qualified machinist using appropriate carbide or high-speed tooling rated for tool steel. Always follow established heat-treatment procedures for A2 grade - including proper austenitizing temperature, air-quench method, and double-temper cycle - when hardening this material. Wear appropriate PPE including eye protection and cut-resistant gloves when handling and cutting bar stock. Consult the material specification sheet for full heat-treatment parameters before processing.
