1-3/4" Diam Tool Steel A-2 Air Hardening Drill Rod MPN:40100448

The A-2 air-hardening drill rod, composed of medium carbon steel, is ideal for crafting cutting tools like drill bits, taps, dies, and broaches among other machine tool applications due to its ability to attain a higher hardness rating when heat treated. Its 1-3/4 inches diameter is perfect for creating precision machined components with its coldwork properties suitable for steel, alloy or stainless steel making it indispensable in the tool and die industries, manufacturing sectors where drilling, reaming, and cutting operations are a requirement. The air-hardening aspect offers greater durability under impact stress when used on materials such as mild steel while being capable of resharpening when worn, making it cost-effective and ideal for the aerospace, construction, automotive and general manufacturing industries needing high precision cutting tools.
