Need some tough, precise round stock for your workshop projects? This set of 5 High-Speed Steel (HSS) rods is perfect. Each rod is 5.4mm in diameter (about 0.21 inches) and 100mm long (roughly 3.93 inches). HSS is known for its excellent hardness (around HRC 61-63) and red hardness, meaning it keeps its edge even when it gets hot from friction – great for tools. You can use these for all sorts of things: making custom lathe tools, small shafts, gears, drill bits, boring bars, miniature axles, pins, or even craft projects. The surface is smooth and they're easy to machine or cut to your desired length. A quick heads-up: because they're slender and hardened, they might have a slight warp or bend (it's normal for HSS rods this size), so they're not ideal for super high-precision applications where perfect straightness is critical. Store them with a bit of oil to prevent rust. For hobbyists, machinists, and DIYers, these are versatile, affordable blanks to have on hand.
