Tight-Tolerance Easy-to-Machine W1 Tool Steel Rods

Yield Strength: 50,000 psi
Hardness: Rockwell B95 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C65
Specifications Met: ASTM A686

These rods, also called drill rod, are ground and held to strict diameter and straightness tolerances. They are ready to be turned in a lathe. With lower amounts of alloy elements than other tool steels, W1 offers excellent machinability. This water-hardening material is often used for hammers, files, taps, and reamers. These rods are decarb-free for a uniform surface that will consistently accept heat treating.
