Drill Rod Tool Steels 03720075 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03720075 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require a reliable, dimensionally consistent steel blank. A2 tool steel offers good wear resistance, moderate toughness, and minimal distortion during air-hardening heat treatment. This flat stock measures 0.75 inches thick by 1.25 inches wide by 36 inches long and weighs approximately 9.94 pounds. It ships in a ready-to-machine condition, making it suitable for fabricating punches, dies, gauges, and cutting tools where tight dimensional control is required before and after hardening.

This flat stock is used in tool and die shops, machine shops, and maintenance departments for manufacturing and repair of tooling components. Typical applications include blanking dies, forming dies, trim dies, stripper plates, and wear pads. The air-hardening characteristic of A2 steel reduces warping during heat treat, making it a preferred choice over oil-hardening grades when dimensional stability after hardening is a priority. It suits both one-off tooling builds and short-run production tooling.

Key Features

• A2 air-hardening tool steel with minimal distortion during heat treatment compared to oil-hardening grades
• Thickness of 0.75 inches, width of 1.25 inches, length of 36 inches in a single flat bar
• Thickness tolerance of +0.010 to 0.015 inches for consistent stock removal planning
• Width tolerance of +0.010 to 0.015 inches
• Length tolerance of +0.250 to 0.500 inches
• Square tolerance of +/- 0.003 inches for reliable reference surfaces during layout and machining

Compatibility

Designed as a standard A2 tool steel flat stock blank suitable for use in any application calling for AISI A2 air-hardening tool steel in 0.75 inch by 1.25 inch cross-section bar form.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified machinists or toolmakers familiar with A2 steel properties. Always follow established shop safety practices when cutting, grinding, or milling tool steel, including use of appropriate PPE and machine guarding. Heat treatment, including hardening and tempering, should follow the material manufacturer's published guidelines for AISI A2 steel and be performed in a controlled atmosphere furnace where possible to minimize decarburization. Allow the bar to normalize to room temperature before precision layout or finish grinding.
