DIYers and machinists, listen up! These uxcell round steel rods are made from High-Speed Steel (HSS), which means they're tough, heat-resistant, and perfect for all sorts of projects. Each rod is 3.9mm in diameter and 100mm long, and you get 5 pieces in a pack. They're great for making or replacing parts like shafts, gears, drills, lathe tools, and miniature axles. The surface is smooth, so they're easy to shape, cut, and form without cracking. Just a heads-up: there might be slight warping (about 0.25mm over 25mm), but for most general uses, it won't be an issue. They're not recommended for super high-precision coaxial work, but for everything else – like crafting, boring, turning, or milling – they're solid. HSS stays hard even at high temperatures (up to 500°C), so these rods can handle demanding jobs. Store them with a bit of oil to prevent rust, and you're set. Whether you're working on a lathe, boring machine, or a creative DIY project, these rods offer versatility and reliability. Grab a pack and start building!
